COBALT-BASED CATALYST HAVING MAIN FRAMEWORK OF MESOPOROUS STRUCTURE FOR FISCHER-TROPSCH SYNTHESIS AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a mesoporous cobalt-metal oxide catalyst for Fischer-Tropsch synthesis and a method for preparing the same. The mesoporous cobalt-metal oxide catalyst for Fischer-Tropsch synthesis according to the present invention maintains the mesoporous structure thereof very stably even under a hydrogen-enriched high-temperature reductive condition or low-temperature Fischer-Tropsch synthesis condition, and facilitates transfer of reactants to the active points of the catalyst and discharge of a high-boiling point hydrocarbon product after the production thereof by virtue of the structural stability. In addition, unlike the conventional cobalt-based catalysts obtained by adding various co-catalysts for the purpose of increasing reduction capability, activity, selectivity and thermal stability, the mesoporous cobalt-metal oxide catalyst for Fischer-Tropsch synthesis according to the present invention maintains a high degree of conversion and selectivity constantly while requiring no co-catalyst, and thus is very useful for Fischer-Tropsch synthesis.;COPYRIGHT KIPO 2017
