- 摘要：
A process for producing alkyl esters useful as bio-fuels and/or lubricants. An alkyl ester product produced by the process. The process comprises a single-stage reaction for esterifying a de-watered glyceride-containing feedstock with an anhydrous short chain alcohol in the presence of a basic esterification catalyst to produce a reaction product comprising alkyl esters and a reaction by-product comprising glycerol-containing substances and the catalyst-containing alcohol. The single-stage esterification reaction is conducted within a temperature and negative-pressure controllable vessel. The alkyl ester product is separated from the re-action by-product and may be further de-watered and/or purified. The catalyst-containing alcohol may be separated from the reaction by-product, de-watered and reused. The glycerol-containing substances may be separated from the reaction by-product and further purified. Useful glyceride-containing feedstocks include those prepared from plant or animal or fish materials, part
