Mesoporous cobalt-metal oxide catalyst for fischer-tropsch synthesis reactions and a preparing method thereof

Abstract

The present invention relates to a mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis and a method of preparing the same. The mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis of the present invention can very stably maintain the mesoporous structure even under a H-rich high-temperature reduction condition and under a reaction condition of the low-temperature Fischer-Tropsch synthesis, easily transport reactants to the active site of the catalyst due to structural stability, and facilitate the release of heavier hydrocarbon products after production thereof. Additionally, unlike the conventional cobalt-based catalysts which are prepared by adding various co-catalysts for the purpose of improving reducibility, activity, selectivity and increasing thermal stability, etc., the mesoporous cobalt-metal oxide catalyst for the Fischer-Tropsch synthesis can constantly maintain conversion and selectivity at high levels without further requiring co-catalysts and thus it can be very effectively used for the Fischer-Tropsch synthesis.
