Abstract: Heterogeneous transesterification of waste cooking palm oil (WCPO) to biodiesel over Sr/ZrO2 catalyst and the optimization of the process have been investigated. Response surface methodology (RSM) was employed to study the relationships of methanol to oil molar ratio, catalyst loading, … Continue reading →

Abstract: Screening and catalytic activity of alkaline modified zirconia i.e. Mg/ZrO2, Ca/ZrO2, Sr/ZrO2, and Ba/ZrO2 as heterogeneous catalyst in biodiesel production from waste cooking oil (WCO) have been investigated. The catalysts were prepared via wet impregnation of alkaline nitrate salts supported … Continue reading →

Abstract: Treatment of sulfamethoxazole (SMX) in terms of total organic carbon (TOC) by combined adsorption and catalytic ozonation by commercial activated carbon (PAC) and Fe2O3/CeO2 loaded activated carbon (MOPAC) has been investigated. Adsorbent dosage of 2 g/L, initial pH ~ … Continue reading →

Abstract: The performances of HZSM-5 and transition metal-loaded HZSM-5 (Mn, Cu, Fe, Ti) catalysts during catalytic ozonation of phenol have been investigated. It was observed the performance order for removal of phenol and COD was Mn/HZSM-5 > Fe/HZSM-5 > Cu/HZSM-5 … Continue reading →

Abstract: Hydrothermal liquefaction is a technique for obtaining clean biofuel from biomass in the presence of a solvent at moderate to high temperature (250–550 °C) and pressure (5–25 MPa). Hydrothermal decomposition of biomass leads to the formation of various compounds depending upon … Continue reading →

Abstract: A thermodynamic equilibrium analysis on the multi-reaction system for carbon dioxide reforming of methane in view of carbon formation was performed with Aspen plus based on direct minimization of Gibbs free energy method. The effects of CO2/CH4ratio (0.5–3), reaction … Continue reading →

Abstract: Major problem in CO2 reforming of methane (CORM) process is coke formation which is a carbonaceous residue that can physically cover active sites of a catalyst surface and leads to catalyst deactivation. A key to develop a more coke-resistant … Continue reading →

Abstract: ZSM-5 zeolite is an acidic catalyst that is highly potential for the conversion of natural gas to liquid fuels. One of the variables that controls the acidity of the ZSM-5 is its Si/Al ratio. Loading the ZSM-5 zeolite with … Continue reading →

Abstract: This study examines the effect of pH of solution, cephalexin (CEX) concentration, and O3 dosage on removal of CEX by catalytic ozonation. All three parameters were found to exert a significant effect on the removal of cephalexin and on … Continue reading →

Abstract: This study is aimed at investigating the interactive effects of reaction parameters such as temperature (330–370 °C), total pressure (30–50 bar) and liquid hourly space velocity LHSV (1–3 h−1) on the performance of hydrodesulfurization (HDS) activity. Experiments were performed based on the … Continue reading →
