Methods for making high-surface area, high-porosity, stable metal oxides, such as, but not limited to materials used as adsorbents and catalyst supports include (i) forming a solvent deficient precursor mixture from a metal salt and a base and reacting the metal ions and base ions in the solvent deficient precursor mixture to form an intermediate hydroxide product (e.g., metal hydroxide or metal oxide hydroxide), (ii) causing the intermediate hydroxide to form nanoparticles (e.g., by heating), and (iii) calcining the intermediate nanoparticles to sinter the nanoparticles together and yield a highly porous, stable metal oxide aggregate having a pore structure.

Method for making highly porous, stable metal oxides with a controlled pore structure

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&#xb0; 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&#xb0; C. and carbiding the reduced metal in the case of iron.

Iron and cobalt based fischer-tropsch pre-catalysts and 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.
