Abstract

The ultrasound-assisted depolymerization of κ-carrageenan has been studied at various temperatures and times. The κ-carrageenan with initial molecular weight of 545 kDa was dispersed in water to form a 5 g/L solution, which was then depolymerized in an ultrasound device at various temperatures and times. The viscosity of the solution was measured using Brookfield viscometer, which was then used to find the number-average molecular weight by Mark-Houwink equation. To obtain the kinetics of κ-carrageenan depolymerization, the number-average molecular weight data was treated using midpoint-chain scission kinetics model. The pre-exponential factor and activation energies for the reaction are 2.683×10-7 mol g-1 min-1 and 6.43 kJ mol-1, respectively. The limiting molecular weight varies from 160 kDa to 240 kDa, and it is linearly correlated to temperature. The results are compared to the result of thermal depolymerization by calculating the half life. It is revealed that ultrasound assisted depolymerization of κ-carrageenan is faster than thermal depolymerization at temperatures below 72.2°C. Compared to thermal depolymerization, the ultrasound-assisted process has lower values of Ea, ΔG‡, ΔH‡, and ΔS‡, which can be attributed to the ultrasonically induced breakage of non-covalent bonds in κ-carrageenan molecules.

Abstract

Octahedral manganese oxide molecular sieves (OMS-2) was prepared by precipitation method and modified by impregnation of titanium with different titanium/manganese (Ti/Mn) ratio. It was also discovered that Ti/Mn ratio of less than 0.5 still retains the original pure cryptomelane structure of OMS-2. However, for sample with Ti/Mn ratio of more than 0.5, some rutile phases of titania (TiO2) can be detected together with the cryptomelane phase. Lewis acid sites were also observed in the titanium modified OMS-2 (Ti-OMS-2). Ti-OMS-2 was then used as catalysts for the oxidation of cyclohexane, cyclohexene and styrene, where Ti-OMS-2 with Ti/Mn ratio of 0.67 was most active in all three of the oxidation reactions as compared to TiO2 and OMS-2. The results suggest that both titanium sites in framework and non-framework and the Lewis acidity created by the impregnation of Ti, increased the activity of OMS-2 in oxidation reactions. © 2014 by Authors, Published by BCREC Group.

Abstract

Di pabrik urea, konverter-hidrogen adalah satu reaktor yang berfungsi untuk mengkonversi hidrogen yang terikut dalam karbondioksida dengan cara mengoksidasi dengan udara, sehingga karbondioksida umpan reaktor urea itu hanya mengandung tidak lebih dari 100 ppm hidrogen. Konversi dilangsungkan pada tekanan 145 kg/cm2 dan suhu umpan reaktor 130°C, menggunakan katalis platinum berpenyangga alumina (0,3%Pt/Al2O3). Dalam dua tahun terakhir, terjadi kenaikan kandungan hidrogen dalam karbondioksida umpan konverter-hidrogen Kaltim-3 yang menyebabkan peningkatan temperatur keluaran konverter dari biasanya sekitar 152oC menjadi sekitar 190°C. Hasil analisis kadar Pt, luas permukaan katalis dan dispersi Pt terhadap katalis-baru dan katalis-terpakai menunjukkan bahwa katalis konverter-hidrogen Kaltim-3 telah terdeaktivasi. Oleh karena itu, pada kesempatan perbaikan-tahunan Juli 2006 yang lalu, katalis tersebut telah diganti dengan yang baru. Selain itu telah dilakukan pula perbaikan kondisi operasi di pabrik amoniak Kaltim-3, sehingga kadar H2 dalam aliran CO2 umpan pabrik urea Kaltim-3 menjadi normal kembali (0,4%). Dengan tindakan-tindakan tersebut, sejak Agustus 2006 yang lalu konverter hidrogen Kaltim-3 dapat beroperasi secara normal kembali. © 2007 by Authors, Published by BCREC Group.

Abstract

Thermally stable polyimides (PIs) were prepared by condensation technique at 160 ºC for 5 hours in N-methylpyrrolidone (NMP) medium under N2 atmosphere both in the presence and absence of metal (Ag) and metaloxide (MO) (V2O5) nanoparticles (NPs). The synthesized polymers are characterized by Fourier Transform Infra Red (FT-IR) spectroscopy, 1H Nuclear Magnetic Resonance (1H NMR) spectroscopy, Differential Scanning Calorimetry (DSC), Thermal Gravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Field Emission Scanning Electron Microscopy with Energy Dispersive X-Ray (FE-SEM and EDX). The FT-IR spectrum showed a peak at 1786 cm-1 corresponding to the C=O stretching of dianhydride. The aromatic proton signals appeared between 6.7 and 7.5 ppm in the 1H-NMR spectrum of the resultant PIs. The oxydianiline (ODA) based PI with Ag NP loaded system exhibited the highest Tg value. The apparent rate constant values for the adsorption and catalytic reduction of p-nitrophenol (PNP), Cr6+ and rhodamine 6G (R6G) dye were determined with the help of UV-visible spectrophotometer. Among the catalysts, the system loaded with V2O5 NP has higher kapp values. The experimental results are critically analyzed and compared with the previously available literature values. Copyright © 2020 by Authors, Published by BCREC Group.

Abstract

Reaction kinetics of esterification of propionic acid with 1-propanol to produce n-propyl propionate using Amberlyst-15 as a catalyst was investigated in this work. Effect of various parameters was studied. Initially, the efficacy of different catalysts was investigated which revealed that Amberlyst-15 can be suitably used for the reaction. This was followed by mass transfer exclusion which included effect of agitation speed, catalyst size and calculation of Weisz-Prater Criterion. Parameters selected for kinetic study were mole ratio of propionic acid to 1-propanol, temperature, catalyst loading and initial water concentration. Catalyst reusability was also verified. Aspen      Custom Modeler (ACM) was used to regress kinetic parameters and a good match was obtained. Reactive Distillation (RD) runs in the batch mode were performed which showed that RD is a better option for process intensification (PI) for this reaction.

Abstract

The development of a mathematical model for explaining the kinetics of flocculation and coalescence of emulsion droplets is essential to study the stability of an emulsion system of the kinetics of emulsion stability. Mathematic models was developed from the equation Van Den Tempel by modifying emulsion systems. The emulsion was made by mixing water-xylene and surfactant tert-butyl oleyl glycosides. This research studied the effect of stirrer speed on the value of flocculation rate constant (a) and coalescence rate constant (K). The model identified the emulsion development condition whether controlled by coalescence or flocculation. It was observed that under lower agitation speed (1000 rpm) the emulsion development was controlled by flocculation mechanism, while a faster agitation (2000 rpm or higher) exhibited coalescence controlled mechanism. The results confirmed that the 1st model was the most appropriate for water-xylene-TBOG emulsion system. From four models after fitting with experimental data, the most suitable model is 4th model, because it has the smallest error of 2.22 %.

Abstract

Oxidative desulfurization process (ODS), enhanced with a novel metal oxide (Ag ions) as an active component over nano-zeolite that has not been reported in the literature, is used here to improve the fuel quality by removing mercaptan (as a model sulfur compound in the light naphtha). Nano-crystalline (nano-support (Nano-zeolite)) composite is prepared by Incipient Wetness Impregnation method loaded with a metal salt to obtain 0.5, 1 and 1.5% of Ag2O3 over Nano-zeolite. The new homemade nano-catalysts (Ag2O3/Nano-zeolite) prepared are characterized by Brunauer–Emmett–Teller (BET) (surface area, pore volume and pore size), X-ray Diffraction (XRD), Fourier Transform Infra Red (FTIR), and Scanning Electron Microscopy (SEM) analysis. The ODS process is then used to evaluate the performance of the catalysts for the removal of sulfur at different reaction temperatures (80–140 °C) and reaction times (30–50 min) in a batch reactor using the air as oxidant. 87.4% of sulfur removal has been achieved using 1% silver oxide loaded on Nano zeolite (1% of Ag2O3/Nano-zeolite) giving a clear indication that our newly designed catalyst is highly efficient catalyst  in the removal of sulfur compound (mercaptan) from naphtha. A new mechanism of chemical reaction for sulfur removal by oxygen using the new homemade catalyst (Ag2O3/Nano-zeolite) prepared has been suggested in this study. The best kinetic model parameters of the relevant reactions are also estimated in this study using pseudo first order technique based on the experimental results.

Abstract

The preparation of CuAl LDH and biochar (BC) composite derived from rice husk and its application as a low-cost adsorbent for enhanced adsorptive removal of malachite green has been studied. The composite was prepared by a one-step coprecipitation method and characterized by X-ray Diffraction (XRD), Fourier Transform Infra Red (FTIR), Brunauer-Emmett-Teller (BET), and Scanning Electron Microscopy - Energy Dispersive X-ray (SEM−EDX). The result indicated that CuAl LDH was successfully incorporated with the biochar that evidenced by the broadening of XRD peak at 2θ = 24° and the appearance of a new peak at 1095 cm−1 on the FTIR spectra. The BET surface area analysis revealed that CuAl/BC composite exhibited a larger surface area (200.9 m2/g) that the original CuAl LDH (46.2 m2/g). Surface morphological changes also confirmed by SEM image, which showed more aggregated particles. The result of the adsorption study indicated the composite material was efficient in removing malachite green with Langmuir maximum adsorption capacity of CuAl/BC reaching 470.96 mg/g, which is higher than the original CuAl LDH 59.523 mg/g. The thermodynamic analysis suggested that the adsorption of malachite green occurs spontaneously (ΔG < 0 at all tested temperature) and endothermic nature. Moreover, the CuAl/BC composite showed strong potential as a low-cost adsorbent for cationic dye removal since it showed not only a high adsorption capacity but also good reusability. Copyright © 2020 by Authors, Published by BCREC Group.

Abstract

Medan orange peel (Mopl), which has been modified using cetyltrimethylammonium bromide (CTAB), has the potential to adsorb methyl orange (MO), and thus it can be used as a supporting material for ZnO. The ZnO is a photocatalytic material that is environmentally friendly, inexpensive, non-toxic, and has a wide band gap value. This study aims to determine the effect of calcination temperature on ZnO and ZnO characteristics due to modification using Mopl-CTAB and its effect on the degradation of MO. This research was carried out by synthesizing ZnO and ZnO/Mopl-CTAB materials using impregnation method and varying the calcination temperatures at 150, 250, 350, and 450 °C. The solid material powder obtained was characterized by using Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDX), Brunauer–Emmett–Teller (BET), Fourier Transform Infra Red (FTIR), X-ray Diffraction (XRD), and Diffuse Reflectance Spectroscopy (DRS). Based on the results of the characterization, greater calcination temperature can affect the characteristics of the photocatalyst, including its morphology, functional groups, crystal structure, crystal lattice, crystallinity, surface area, pore size, pore volume, and energy band gap. The MO photodegradation activity test using the synthesized material was conducted under dark and light conditions. The results of the test revealed that the best or optimum material to be used in degrading MO is a calcined material at 450 °C under light conditions. ZnO material using Mopl-CTAB is better in degrading ZnO/Mopl-CTAB 450 °C than ZnO 450 °C. This study found that ZnO material using Mopl-CTAB  had a percent removal of 78% in 50 min, while ZnO 450 °C only had a percent removal of 53% in 40 min. The reaction kinetics in dark and light conditions follow the pseudo-second-order kinetic model. Copyright © 2023 by Authors, Published by BCREC Group.
