The purposes of the work to study the fatty acid methyl ester production by transesterification of Jatropha curcus oil with different catalysts where methanol was used as solvent. Jatropha oil having high free fatty acids FFA (14.02%) was processed in two steps. First step is acidcatalyzed esterification by using 1% H2SO4, 40% methanol-to-oil to produce methyl esters by lowering the acid value, and next step is different base-catalyzed transesterification. As part of ongoing efforts to investigate different homogeneous, heterogeneous and solid acid catalysts for biodiesel synthesis, the catalytic activity of KOH, NaOH, Ca(OH)2, activated Ca(OH)2, Hß zeolite and montmorillonite were studied for the transesterification of Jatropha oil. Among these catalysts, performance of catalysts order are KOH > NaOH > activated Ca(OH)2 >Ca(OH)2> montmorillonite> Hß zeolite.Key words: Jatropha oil; Transesterification; Biodiesel; FFA; CatalystsDOI: 10.3329/bjsir.v45i2.5702Bangladesh J.

Supernatant Liquid

A systematic and structure-agnostic method for identifying heterogeneous activity of solid acids for catalyzing cellulose hydrolysis is presented. The basis of the method is preparation of a supernatant liquid by exposing the solid acid to reaction conditions and subsequent use of the supernatant liquid as a cellulose hydrolysis catalyst to determine the effects of in situ generated homogeneous acid species. The method was applied to representative solid acid catalysts, including polymer-based, carbonaceous, inorganic, and bifunctional materials. In all cases, supernatant liquids produced from these catalysts exhibited catalytic activity for cellulose hydrolysis. Direct comparison of the activity of the solid acid catalysts and their supernatants could not provide unambiguous detection of heterogeneous catalysis. A reaction pathway kinetic model was used to evaluate potential false-negative interpretation of the supernatant liquid test and to differentiate heterogeneous from homogeneous effects on cellulose hydrolysis. Lastly, differences in the supernatant liquids obtained in the presence and absence of cellulose were evaluated to understand possibility of false-positive interpretation, using structural evidence from the used catalysts to gain a fresh understanding of reactant–catalyst interactions. While many solid acid catalysts have been proposed for cellulose hydrolysis, to our knowledge, this is the first effort to attempt to differentiate the effects of heterogeneous and homogeneous activities. The resulting supernatant liquid method should be used in all future attempts to design and develop solid acids for cellulose hydrolysis.
