Abstract

Sesame oil was treated to produce fatty acid methyl esters (FAMEs) in supercritical methanol medium in presence of CaO and MgO catalysts supported on γ-Al2O3. Reaction was performed in a 50mL stainless steel micro-reactor at 300oC and 80 MPa. Catalysts were characterized using XRD, ICP and SEM techniques. Liquid products were analyzed using GC-MS and CaO/Al2O3 showed higher FAME production yield than MgO/Al2O3. Alkanes and aromatics are byproducts of reaction. The produced FAMEs were completely unsaturated ones that can be demonstrated that hydrogen gas production in the medium. Results showed that 63%wt and 86%wt of triglycerides were converted to methyl esters in presence of MgO/Al2O3 and CaO/Al2O3, respectively.

Abstract

Conversion of Iranian bagasse to gaseous and liquid fuels was carried out in a basic and reducing medium of subcritical water and supercritical methanol with 80%wt and 20%wt, respectively.The process was performed in a bomb 200 mL reactor in presence of Cu /γAl -MgO catalysts. The catalysts were promoted with different percentages of K and the effects of Cu and Kloadings on quality and quantity of biofuel products were investigated. The catalysts wereprepared with 20wt% of Cu and 1, 2.5, 5, 7.5 and 10wt% of K. They were shown in the text withCu20, Cu20-K1, Cu20-K2.5, Cu20-K5, Cu20-K7 and Cu20-K10, respectively. 3
