LIPASE IMMOBILIZED MEMBRANE REACTOR APPLIED TO BABASSU OIL HYDROLYSIS

This work deals with enzymatic hydrolysis of babassu oil by immobilized lipase in membrane reactors of two types: a flat plate nylon membrane and a hollow fiber polyetherimide membrane on which surface commercial lipases were immobilized by adsorption. Experiments conducted in the hollow fiber react...
