In the study, to improve the efficiency of acid-catalyzed biodiesel production process, three acidic imidazolium ionic liquids were synthesized and employed to the production of biodiesel from palm oil under microwave irradiation. The prepared ionic liquids were characterized by NMR, FT-IR and TG-DTG. Among the three ionic liquids, ([HSO3-BMIM]HSO4) was proved to be the most suitable catalyst because...
In the present study, the kinetics of transesterification of palm oil was explored under conventional heating and microwave irradiation, using CaO as heterogeneous catalyst. The optimal experimental conditions were, microwave power of 150W, alcohol to oil molar ratio of 9:1, catalyst of 5%, stirring speed of 450r/min and reaction time of 60min. By establishing kinetic models, the total reaction orders...
In this work, a series of carbon supported PtAuFe catalysts are prepared via a microwave-irradiated polyol process. Both the synthesis route and the content of Fe in the catalysts are investigated. The single cell tests and the gas chromatography analyses reveal that the PtAuFe/C catalysts are promising as CO-tolerant anode electro-catalysts for proton exchange membrane fuel cells application. On...
