Abstract
The present invention relates to a process of formulating and preparing supported multi-metal catalysts based on metal oxides and inorganic salts of metals. The impregnation technique is employed by two methods: the slurry method and the modified-pH variation method, which are used in two steps for obtaining the catalyst. The present invention also relates to a process called Glycerol to Propene (GTP) process, corresponding to the transformation of glycerol or glycerin to propene. The reaction involved in the process of the present invention is the selective hydrogenation of glycerin, which takes place by contact of the charge of glycerin carried by hydrogen in a continuous stream system on the catalytic bed containing multi-metal catalysts, specifically prepared for this purpose.
