Patent number: 10689607Abstract: Disclosed are an enzymatic batchwise or continuous process for the production of fatty acid alkyl esters for use in the biofuels, food and detergent industries and a system therefor. The process utilizes enzymes immobilized on a hydrophobic resin mixed with a fatty acid source and an alcohol or alcohol donor in the presence of an alkaline or mild alkaline aqueous buffer, or in the presence of water or aqueous solution. The production process for fatty acid alkyl esters is carried out by transesterification or esterification simultaneously or sequentially. The biocatalyst activity is maintained with no significant activity losses in multiple uses and also avoids the accumulation of glycerol and water by-products or other hydrophilic compounds on the biocatalyst.Type: GrantFiled: May 21, 2018Date of Patent: June 23, 2020Assignee: Trans Bio-Diesel Ltd.Inventors: Sobhi Basheer, Maisa Haj, Usama Mohsen, Doaa Shehadeh, Ahmad Hindawi, Emad Masoud, Ahmad Egbarieh, Ramez Masri
