The present invention relates to a method for preparing a cobalt-based catalyst for Fischer-Tropsch synthesis, more particularly to a method for preparing a cobalt-based catalyst represented by Ir&#x2014;Co/&#x3b7;-AlOwherein cobalt and iridium are supported at high density by repeating impregnation and drying tens of times on a spherical &#x3b7;-alumina support having many acidic sites. The catalyst prepared according to the present invention can provide improved conversion rate of carbon monoxide and selectivity for liquid hydrocarbons when used for Fischer-Tropsch synthesis.

The present invention relates to a method for preparing a nickel-based catalyst for steam carbon dioxide reforming (SCR) of natural gas using steam and carbon dioxide, more particularly to a method for preparing a nickel-based catalyst represented by Ni/&#x3b7;-AlO, which is prepared by supporting nickel on a spherical &#x3b7;-alumina support having many acid sites at high density by repeating impregnation and drying tens of times. The catalyst prepared according to the present invention exhibits superior catalytic activity when used in steam carbon dioxide reforming reaction (SCR) even under harsh conditions of high temperature and high pressure and hardly exhibits carbon deposition due to superior durability.

Process for preparing nickel based catalysts for SCR of natural gas

Disclosed is a catalyst used for steam carbon dioxide reforming of natural gas, wherein an alkaline earth metal alone or an alkaline earth metal and a group 8B metal are supported on a hydrotalcite-like catalyst containing nickel, magnesium and aluminum. The disclosed catalyst is useful as a steam carbon dioxide reforming (SCR) catalyst of natural gas at high temperature and high pressure, while minimizing deactivation of the catalyst due to sintering of the active component nickel and deactivation of the catalyst due to coke generation at the same time. A synthesis gas prepared using the catalyst has a H/CO molar ratio maintained at 1-2.2. A synthesis gas having a H/CO molar ratio of 1.8-2.2 may be used as a raw material for Fischer-Tropsch synthesis or methanol synthesis and a synthesis gas having a H/CO molar ratio of may be used as a raw material for dimethyl ether synthesis.
