Biodiesel production using aminated fibrous polymer catalyst in packed continuous reactor

A solid polymer catalyst in a form of aminated ion exchange fibers having basic functionality was prepared by amination (treatment with triethylamine) of a fibrous grafted copolymer precursor obtained by radiation induced grating of glycidyl methacrylate (GMA) onto polyethylene (PE) fibers. The obta...
