SYNTHESIS OF TRIMETHYLOLPROPANE ESTER BASED ON CHICKEN FAT AS BIOLUBRICANTS

Revista Mexicana de Ingeniería Química, 2018
In this project, chicken fat was transesterificated to methyl esters of chicken fat (MECF) with an efficiency of 80%, subsequently added trimethylolpropane (TMP) to get as majority product esters of trimethylolpropane (biolubricants). Temperature, molar ratio MECF:TMP and catalyst were evaluated using a mixed-level factorial design.

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...
