Abstract

Research on catalytic reaction of ethanol to gasoline (ETG) was investigated in this study. The catalyst with a high acidity is required for the ETG reaction. Therefore, this study focused on the catalyst preparation of ETG reaction by using natural clays which prepared by the pillarization techniquewithseveral metal oxides, such as:AI, Zr, Fe and Cr as the pillared. The prepared of pillared clay were characterized by x-ray diffraction, specific surface area and pore distribution (BET) measurements and  catalytic activity testing on the ETG reaction. It is observed that after the pillarization; the surface area and basal spacing (d001) of the natural clays were significantly increased. thus the   ptllarization process was successfully prepared on natural clay. However,the acidity of theprepared ofpillared clay is still  lower,probably due to the cations between layers of the natural clay were not homogeneous, thus although the pillarization process was happen but still not completely. Moreover, IR measurement showed only the acid type of Lewis is increased after the pillarization. Thistype is not favorable for the ETG reaction, and thus only the lower hydrocarbon products (<Cl2) were observed after the ETG reaction, even aromatics and cyclic hydrocarboncompounds wereobtainedKeyword : preparation, pillared clay, catalyst, ETG reaction.

Abstract

Renewability Indicator (RI) and Cumulative Degree of Perfection (CDP) were used to observe sustainability of Gamboeng Tea. The assessment then compared with black tea process in Black Sea Region in Turkey from the previous study. Calculation of exergy for Gamboeng fresh tea leaf had already described in Part.1. Since the main process for both production was drying, then tropical humid climate in Gamboeng is the main challenge to increase efficiency, and thus, renewability. This second part described the significant improvement of renewability had applied in Gamboeng by using wood pellet in rotary pannier. Further recommended improvement were by installing better humidity detector and connected to the process control so the process can adapt the ambient change which the relative humidity can be varied from 65% and up to 92%.

Abstract

In this study, a simulation for gasification process of oil palm empty fruit bunches waste (OPEFB) using a fixed bed gasifier (throat downdraft) by varying the particle size of OPEFB and equivalence ratio (ER) was investigated. The rate of fuel consumption was 10 kg/h with air as the oxidizing medium and 1 hour process time for 1 batch. Simulation was performed with two-dimensional approach (2D) using Computational Fluid Dynamics (CFD) ANSYS FLUENT 14 software. Simulation results show that ideal amount of equivalence ratio (ER) for gasification process of OPEFB pellets with diameter (φ) of 6 mm and 8 mm is 0.1 ≤ ER ≤ 0.2. ER variation affects the higher heating value of syngas (HHV), the carbon efficiency (ηC), gasification efficiency and temperature distribution in the gasification reactor. Variations in particle size did not have a significant effect in the gasification process.Keywords: CFD, OPEFB gasification, particle size, equivalence ratio

Abstract

Biomass gasification has been widely known method to produce syn-gases, which can be considered as great alternative substitution for fossil fuels. However, accurate verification of the syn-gas composition requires a reliable and validated method for simultaneous measurement of H2, CO2, CH4, and CO. In order to fulfill the aforementioned requirements, which is the objective of this study; a GC-TCD method for simultaneous measurement of H2, CO2, CH4, and CO component in syn-gas has been validated in accordance to ISO/IEC 17025 and its application for real samples. For the method validation purpose, all of the performance parameters were evaluated and discussed in detail in this study. Intraday precision and interday precision were found to be acceptable having the %RSD below 0.67xCV Horwitz and below 1.0xCV Horwitz, respectively. The bias value falls within +2? for entire components, indicating that the method accuracy can be accepted. Coefficient correlation for all components was higher than 0.99, which means that the method has suffi cient linearity. LoD and LoQ for each component were found to be lower than typical syn-gas concentration range. The method roughness was also found in an acceptable level (the p-values was higher than 0.05 for allctarget components. Application of the validated method for the measurement of a real syn-gas samples indicated that the method is quite reliable to produce an accurate data and the validated methid can be used in a routine analysis. The innovation of this study, as shown by experiment results, is to evaluate the validated methods performance for simultaneous determination of syn-gas components concentration in one channel, compared to common method in which the syn-gas components were measured separatedly in a different channel.
