  • Patent number: 8845998
    Abstract: A catalyst has a long life span and efficiently separates hydrogen from water. A first metal element (Ni, Pd, Pt) for cutting the combination of hydrogen and oxygen and a second metal element (Cr, Mo, W, Fe) for helping the function of the first metal element are melted in alkaline metal hydroxide or alkaline earth metal hydroxide to make a mixture heated at a temperature above the melting point of the hydroxide to eject fine particles from the liquid surface, bringing steam into contact with the fine particles. Instead of this, a mixture of alkaline metal hydroxide and metal oxide is heated at a temperature above the melting point of the alkaline metal hydroxide to make metal compound in which at least two kinds of metal elements are melted, and fine particles are ejected from the surface of the metal compound to be brought into contact with steam.

  • Patent number: 8841497
    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.
