Applications of Super Critical Technology in Biodiesel Production

Abstract

Because of the scarcity of fossil fuels, it's crucial to look into non-conventional options. In this context, "biofuel"refers to any fuel, liquid, gaseous, or solid, that is primarily derived from biomass. Many different types of biofuels exist, including ethanol, methanol, diesel, and hydrogen. Biodiesel, is a promising alternative fuel. It's eco-friendly and manufactured from edible or nonedible oils. Transesterification, non-catalytic supercritical fluid technique, micro emulsion, pyrolysis, and other methods have all been recorded for producing biodiesel from vegetable oil and lipids. This article compares and contrasts the advantages of using conventional catalytic processes to produce biodiesel with those of using supercritical fluids (SCF). Concerns have been raised regarding the substantial amount of energy that must be expended in order to carry out supercritical reactions under conditions of high pressure and temperature. This is despite the fact that the catalyst-free SCF method clearly offers a number of benefits that are hard to ignore. Because of this, the SCF process has significant difficulties that need fixing before it can become a long-term viable technology.
