Patent ID: 8841497

Claim:
A process for selective hydrogenation of glycerin, characterized in that it comprises reacting a feed of glycerin and hydrogen on a multi-metal catalyst comprised by metals of group VI-B of the Periodic Table of Elements and iron (Fe), or their respective oxides, supported on a material selected from activated charcoal powder, aluminosilicates, aluminas, clays, zeolites and molecular sieves, at a temperature ranging from 150° C. to 550° C., under a pressure ranging from 0 kgf/cm 2 to 200 kgf/cm 2 , glycerin/H 2 molar ratio ranging from 1:5 to 1:1000, and glycerin space velocity ranging from 2.0 h −1 to 20 h −1 , for selectively converting glycerin to propene.
