Abstract

Glycerol is known to be a by-product from biodiesel production. Researchers have investigated various means of utilizing this by-product from vegetable oil methanolysis which constitutes about 8-10% wt. in this study, the production of glycerol was initially present in the reactor and dimethyl carbonate was fed at a fixed rate to undergo two reversible reactions-formation of methyl glycerol carbonate intermediate and cyclization to glycerol carbonate. A two-dimensional simulation was also performed to account for the temperature and velocity profile across the reactor geometry. Using COMSOL multiphysics®, momentum transport was assumed to obey the Navier-Stokes equation neglecting entrance effect and outlet viscous stress while convective heat transfer dominate with all other boundaries considered insulated
