Production of FAME from acid oil, a by-product of
Jan 01, 2003· Simple alkyl FA esters have numerous uses, including serving as biodiesel, a fuel for compression ignition (diesel) engines. The use of acid-catalyzed esterification for the synthesis of FAME from acid oil, a by-product of edible vegetable oil refining that is produced from soapstock, was investigated. Soybean acid oil contained 59.3 wt% FFA, 28.0 wt% TAG, 4.4 wt% DAG, and less than

Acid oil is a by-product in the neutralization step of vegetable oil refining and is an alternative source of biodiesel fuel. A model substrate of acid oil, which is composed of TAG and FFA, was used in experiments on the conversion to FAME by immobilized Candida antarctica lipase. FFA in the mixture of TAG/FFA were efficiently esterified with methanol (MeOH), but the water generated by the
By-products from the vegetable oil industry ResearchGate
We have investigated the production of fatty acid methyl esters (FAME; biodiesel) from soapstock (SS), a byproduct of edible oil refining that is substantially less expensive than edible-grade
Acid oil, which is a by-product in vegetable oil refining, mainly contains free fatty acids (FFAs) and acylglycerols, and is a candidate of materials for production of biodiesel fuel. A mixture (acid oil model) of refined FFAs and vegetable oil was recently reported to be converted to fatty acid methyl esters (FAMEs) at >98% conversion by a two
Conversion of acid oil by-produced in vegetable oil
Mar 01, 2007· Acid oil, rapeseed oil rich in oleic acid, and FFAs of the rapeseed oil are products of the Nisshin OilliO Group Ltd. (Tokyo, Japan). The acid oil was centrifuged at 10,000 × g for 15 min to remove precipitates.The composition of the resulting supernatant, referred to as acid oil supernatant, is shown in Table 1.Its acid value and water content was 156 mg KOH/g and 1.1 wt%, respectively.
In majority of the cases, the acid oil is derived from the byproduct of the refining process which is soap stock. Process of Making Acid Oil The soap stock generated from the refinery is collected into the reaction vessel and allowed to heat at a temperature of around 90
