Abstract

The number of motorised vehicles, according to the Central Statistics Agency, reached 94,373,324 in 2012, and there was an increase in 2013 to 104,118,986. This is influenced by increasingly rapid population growth and the increasing need for transportation. Used lubricating oil is categorised as B3 waste, which can be seen from its characteristics and its constituent components. Rice husks resulting from milling that are not utilised optimally are usually only used as ash, or the use of rice husks has so far been limited to just being thrown away. Research was carried out regarding the activated carbon test from rice husk waste to adsorb Pb in used lubricating oil using a sulfuric acid activator and determine the effectiveness of reducing Pb (lead). The mass ratio of rice husks before and after calcination is 1:2, where the initial weight of the husks before calcination is 250 grammes to 125 grammes after undergoing calcination. A mass of 10 grammes of adsorbent that has been activated using sulfuric acid and a stirring time of 60 minutes can reduce the lead content of the used lubricant from 49,569 ppm to 39,241 ppm.

Abstract

Petroleum fuel is still the main energy source today but causes environmental problems such as SOx gas emissions. The Oxidative Desulfurization (ODS) method removes sulfur from fuel under mild conditions. ZSM-5 is a catalyst framework considered promising in the ODS process but the small pores cause a steric barrier. The hydrophobic, mesoporous Fe-Co/ZSM-5Hierarchy catalyst was designed using the dealumination method with steam treatment to overcome the steric barrier and biphasic hindrances which are problems in this ODS process. The Fe-Co/ZSM-5Hierarchy catalyst is effective for the ODS process at a temperature of 45 °C, 45 min, the amount of catalyst used is 0.2 g, oxidant at an O/S ratio of 2, and without mass transfer agents. The embedded Fe-Co ratio shows effective mass activity by providing a TOF number of 205 h-1 on the Fe-Co(5)/ZSM-5 Hierarchy and 157 h-1 on the Fe-Co(15)/ZSM-5 Hierarchy catalyst.

Abstract

This research involved top-down dealumination and steam treatment methods to design the hierarchical pores of ZSM-5, which is then wet-impregnated with a Fe-Co. This method overcomes the steric barrier that hinders the oxidative desulfurization (ODS) process and makes the catalyst hydrophobic, thereby allowing it to overcome the biphasic hindrance caused by the difference in polarity between the fuel oil and the oxidant. Characterization of the catalyst's properties based on BET and BJH, XRF, and contact angle, as well as testing its performance on DBT model oil in n-hexadecane and Indonesian commercial diesel were conducted. Simulation of the reaction energy profile using density functional theory calculations was also carried out to deepen insight into the mechanism of the reaction. Results of this study show that the catalyst has excellent catalytic reactivity in the long-chain hydrocarbon ODS process, with a TOF number of 183 h−1.

Abstract

Industri kendaraan bermotor baik perakitan maupun pembuatan spare part tidak terlepas dari adanya limbah produksi, terutama limbah cair yang harus diolah sebelum dapat dibuang ke lingkungan. Bahan kimia sebagai koagulan seperti Poly Aluminium Chloride (PAC) dan Aluminium Sulfat (tawas) sudah banyak digunakan pada pengolahan limbah cair terutama untuk mengurangi partikel Total Suspended Solids (TSS) dalam rangka mengurangi kekeruhan air. Selain itu proses koagulan ini juga dapat menurunkan Chemical Oxygen Demand (COD) dan Biological Oxygen Demand (BOD).  Studi ini mengkombinasi koagulasi-flokulasi dengan jenis flok yaitu Poly Acrylamide Floculant (PAF), untuk membentuk flok yang mempercepat proses pengendapan semua partikel yang terlarut. Kombinasi ini menjadi kebaruan penelitian ini, karena masih belum banyak dikenal pada proses pengolahan limbah di pabrik sepeda motor, serta menemukan bahan koagulan yang terbaik. Metode pada studi ini yaitu One Group Pretest-Postest, dengan tujuan mengetahui efisiensi PAC dan tawas. Hasil menunjukkan data yang didapat dengan melakukan uji jar test yaitu pada penambahan koagulan, lama pengendapan, serta endapan yang terbentuk. Setelah proses jar test dapat dilihat hasil efisiensi penggunaan bahan-bahan koagulan yang digunakan dapat mempengaruhi limbah cair yang dihasilkan dari pengolahan koagulasi. Berdasarkan penelitian yang telah diuji coba koagulan yang paling baik menurunkan kadar COD, BOD, TSS adalah Poly Aluminium Chloride (PAC) dengan konsentrasi 10% menghasilkan penurunan BOD 94,16% dan COD 94,14% sedangkan penurunan kadar COD dan BOD menggunakan Aluminium Sulfat dengan dosis yang sama, menghasilkan penurunan BOD 83,22% dan COD 81,32%. Selain itu, menggunakan koagulan PAC tidak membuat limbah menjadi keruh dan terbilang aman bagi lingkungan bila pemakaian dosisnya berlebih.

Abstract

Background: Soursop, with the Latin name Annona muricata L, has become one of the herbal medicine materials under extensive development. One of the challenges faced in utilizing extracts from soursop leaves currently is the inefficiency of the solvents used. Methods: This study aims to determine the phenol content present in soursop leaves. The independent variable used is the process of drying soursop leaves before the soxhlet extraction process. The purpose of this process is to increase the phenol content in the concentrated soursop leaf extract after the soxhlet extraction process. Thus, this research involves two processes, namely the soxhlet extraction and distillation processes. Findings: The phenol content obtained from the FT-IR test is approximately 80-85% with an intensity at 3347.82 cm-1. Furthermore, the distillation process is carried out to obtain a distillate that will be tested using GC-MS instrument. The results of the GC-MS test show a value of approximately 1.723 with an area of 78.04. Conclusion: The longer the immersion of soursop leaves and the higher the concentration of the solvent used, the better the results tend to be. Identification of the effects of using different solvents with the same functional groups becomes important in further research.

Abstract

Non-edible oil, such as Jatropha oil, is an interesting feedstock for the development of renewable diesel (green diesel). Catalytic deoxygenation using natural zeolite-supported Mo-based catalysts is a promising process for the conversion of Jatropha oil to green diesel. Mo and MoP catalysts supported on natural zeolite were synthesized by wet impregnation at a concentration of 5% (w/w). The catalysts were characterized by XRD, XRF, SAA and NH3-TPD. The catalysts were successfully synthesized with the appearance of Mo and MoP peaks on the catalyst diffractogram. XRF results also showed that Mo and P were present in the catalyst. Metal impregnation decreased the surface area and pore volume of the catalyst, but increased the average pore diameter. The NH3-TPD profile of the catalyst showed that the weak acid sites of both catalysts were larger than the strong acid sites. Based on the activity test of catalytic deoxygenation of Jatropha oil, the MoP/HZ catalyst produced a higher conversion (67%) and liquid product yield (79%) than Mo/HZ. This is associated with a larger pore diameter, so that the distribution of reactants on the catalyst surface is more optimal. However, the highest green diesel selectivity of 82% is produced by the Mo/HZ catalyst. The Mo/HZ catalyst is more oriented towards the HDO reaction, whereas the MoP/HZ catalyst is more oriented towards the DCO/DCO2 reaction.
