Supercritical carbon dioxide in vegetable oil production

Continuous Production of Biodiesel from Vegetable Oil Using Supercritical Ethanol/carbon Dioxide Mixtures

Biodiesel production is worthy of continued study and optimization of production procedures because of its environmentally beneficial attributes and its renewable nature. Transesterification of triglycerides using supercritical ethanol on ionexchange resin catalyst was investigated to study the ethyl ester conversion process. The reaction parameters investigated were the reaction time, pressure...

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Lipase Catalyzed Ethanolysis of Fish Oil in Supercritical Carbon Dioxide

Ethanolysis of a mixture of tuna and sardine oil catalysed by lipase Lipozyme 435 (Candida antarctica lipase B) has been studied in supercritical carbon dioxide as reaction medium. The reaction products were analysed by Normal Phase-High Performance Liquid Chromatography (NP-HPLC) and High Temperature Gas Chromatography (HTGC). The reaction has been performed in a stirred tank reactor operating...

Supercritical Carbon Dioxide Extraction of Borage Seed Oil

The oil from the seeds of Borago officinalis L. (borage) is a major commercial source of ?-linolenic acid. The fatty acid has a great potential therapeutic value in the treatment of several diseases. In the present work the efficiency of high pressure extraction of borage seed oil containing ?linolenic acid in high concentrations was investigated. Extraction was performed by semicontinuous flow...
