Judul: Biodiesel production from palm oil in a bubble column reactor by non-catalytic process
Abstrak: Biodiesel has been defined as the monoalkyl esters of long-chain fatty acids derived from renewable feedstocks, such as vegetable oils and animal fats, for use in compression-ignition (diesel) engines. Biodiesel, consisting of fatty acid methyl esters (FAME) can be produced by transesterification of triglycerides (TG) and/or esterification of free fatty acids (FFA) in vegetable oils with short-chain alcohol, mainly methanol (MeOH). Alkaline-catalyzed transeseterification of TG in vegetable oils, with the addition of an acid-catalyzed reaction to esterify FFA are the technologies presently in use for industrial-scale biodiesel production. However, the desire to reduce or remove catalyst cost, waste output and to obtain the simpler process has stimulated the investigation of alternate methods of biodiesel synthesis.
