    摘要: A porous catalyst support having an increased average pore size is produced from a mixed metal oxide material. In accordance with one embodiment, a method for preparing a mixed metal oxide material includes providing a mixed metal oxide precursor containing at least two metals, calcining the mixed metal oxide precursor at a temperature sufficient to form a thermally and mechanically stable mixed metal oxide material, and leaching the mixed metal oxide material in a leach solution with a constituent that dissolves one metal oxide. Preferably, the calcination temperature is approximately between 300° C. and 1300° C. The leaching constituent may be chosen from the group including acidic solutions of HCl, HNO3, H2SO4, H3PO3, and their combinations, or basic solutions of NH3, NaOH, KOH, and their combinations.

    摘要: The present invention is an improvement in the preparation of liquid hydrocarbons from natural gas/methane, oxygen and/or steam. In particular, the present invention relates to processes for the production of synthesis gas, reducing the oxygen concentration from the synthesis gas, and the production of liquid hydrocarbons using the oxygen reduced synthesis gas as a feedstock. More particularly, the present invention described herein identifies catalyst compositions, apparatus and methods of using such catalysts and apparatus for preparing liquid hydrocarbons via oxygen reduced synthesis gas all in accordance with the present invention.
