Development And Utilization Of A Pair Of Sol-Gel Entrapped Lipases For Biodiesel Production From High Free Fatty Acid Oils, Cory M. Schwartz
Development And Utilization Of A Pair Of Sol-Gel Entrapped Lipases For Biodiesel Production From High Free Fatty Acid Oils, Cory M. Schwartz
Department of Chemical and Biomolecular Engineering: Theses and Student Research
Biodiesel, which consists of fatty acid alkyl esters, is one of the most widely adopted and successful renewable fuels. Traditional physiochemical biodiesel production methods require high cost refined feedstocks, and so alternative methods of catalysis and feedstocks have been explored. This research investigated the use of polysiloxane entrapped lipases to catalyze the production of biodiesel from low cost feedstocks.
In this work, lipase from Burkholderia cepacia (lipase PS) and lipase B from Candida antarctica (CalB) were separately entrapped using sol-gel chemistry. Optimal reaction conditions for the esterification of free fatty acids by immobilized CalB with methanol were determined. Immobilized CalB …

A conventional biodiesel plant utilizing two distillation columns to purify unreacted reactants and products is considered in this study. Thermodynamic analyses are used to assess the performance of the existing distillation columns, and reduce the costs of operation by appropriate retrofits in a biodiesel production plant. After the retrofits, the overall exergy loss for the two columns has decreased from 2430.87 kW to 1674.12 kW.
A reactive distillation is developed for esterification of lauric acid with methanol using equilibrium and nonequilibrium models. Equilibrium modeling dominated during last few decades due to their straightforward mathematical modeling. In reality, separation depends on …
