20130267411 | SINGLE REACTION SYNTHESIS OF TEXTURIZED CATALYSTS - Methods are described for making a texturized catalyst. The textural promoter may be a high-surface area, high-porosity, stable metal oxide support. The catalyst is manufactured by reacting catalyst precursor materials and support materials in a single, solvent deficient reaction to form a catalyst. The catalyst may be particles or a coating or partial coating of a support surface. | 10-10-2013 |
20130274093 | IRON AND COBALT BASED FISCHER-TROPSCH PRE-CATALYSTS AND CATALYSTS - A method of making iron and cobalt pre-catalysts and catalysts in activated, finished form suitable for use in Fischer-Tropsch synthesis. The pre-catalysts are prepared by mixing an iron or cobalt salt, a base, and a metal oxide textural promoter or support. The reaction is carried out in a solvent deficient environment. The resulting product is then calcined at temperatures of about 300-500° C. to produce a metal oxide. The catalysts are prepared by reducing the metal oxide in the presence of hydrogen at temperatures of about 300-500° C. and carbiding the reduced metal in the case of iron. | 10-17-2013 |
