Abstract
Production of biodiesel, “a green fuel” will be discussed via transesterification of (Jatropha oil, soybean oil and waste cooking oil) over the solid acid catalysts comprising of polyoxometalates (based on phosphotungstate and silicotungstate) and various porous supports (MCM-41, MCM-48 and Zeolite beta). The talk will focus especially on an alternative for low cost biodiesel production by using feedstocks such as low cost raw material-waste cooking oil obtained from canteens, restaurants and from houses. The superiority of the present work lies in getting 90% conversion for biodiesel production under mild conditions. The catalyst shows the potential of being used as a recyclable catalytic material after simple regeneration without significant loss in conversion up-to four cycles. Novelty of the present reaction system was emphasised by obtaining high conversion and identical optimization conditions as compared to the batch scale for transesterification reactions using up to 250 g feedstock. Depending on the requirements, the size of the unit can be scaled up to get higher production capacity without changing any mechanistic requirement of the system. A possible scheme of this integrated process using present catalysts will also be discussed. The overall production process will be economical as the catalyst can be used up to many cycles, total steps can be reduced and methanol can be recycled and reused for subsequent runs. Furthermore, it minimizes the production cost as obtained glycerol can be converted to value added products via various organic transformations.
