Abstract

Biodiesel as alternative fuel is widely produced from various source of vegetable oil. The production of biodiesel also generates large number of by-products, such as glycerol. The limitation of glycerol market, make glycerol the best candidate to propose as feedstock for chemical production because the many possible chemical derivative. Glycerol can be converted to many kinds of chemical products, one of them is formic acid. The oxidation of glycerol with hydrogen peroxide will produced formic acid and water. The simulation process was designed using Aspen Hysys. The reactor feed consists of pure glycerol and hydrogen peroxide 30%. The mole ratio of glycerol and hydrogen peroxide was set to 1:15. The oxidation process was simulated using conversion reactor with conversion 99% at temperature 250C and 170 atm. The process was continued with formic acid purification via distillation and extractive distillation using SULFOLANE. The extractive distillation needed because the azeotrope characteristic of water 22.4%-w and formic acid 77.6%-w. The simulation indicates that from 100 kg/h glycerol can be produced around 113 kg/h formic acid with purity 92%.
