Title:
METHOD FOR MAKING A COBALT METAL FOAM CATALYST IN WHICH A COBALT CATALYST POWDER IS COATED ONTO THE SURFACE OF A METAL FOAM, THE COBALT METAL FOAM CATALYST, A THERMAL-MEDIUM-CIRCULATING HEAT-EXCHANGE REACTOR USING THE COBALT METAL FOAM CATALYST, AND A METHOD FOR PRODUCING A LIQUID FUEL BY MEANS OF A FISCHER-TROPSCH SYNTHESIS REACTION USING THE THERMAL-MEDIUM-CIRCULATING HEAT-EXCHANGE REACTOR
Document Type and Number:
WIPO Patent Application WO/2011/102567
Kind Code:
A1
Abstract:
The present invention relates to a method for making a cobalt metal foam catalyst in which a cobalt catalyst powder is coated onto the surface of a metal foam, the cobalt metal foam catalyst, a thermal-medium-circulating heat-exchange reactor using the cobalt metal foam catalyst, and to a method for producing a liquid fuel by means of a Fischer-Tropsch synthesis reaction using the thermal-medium-circulating heat-exchange reactor, and an object of the present invention is to provide a catalyst which exhibits high liquid-fuel productivity even at low CO conversion rates due to an improvement in mass transfer characteristics in the catalyst layer and reaction temperature adjustment in a stable fashion via highly efficient heat-of-reaction control in the Fischer-Tropsch synthesis reaction which is a severely exothermic reaction and a method for making the same, as well as to provide a reactor using the same and a method for making a liquid fuel by using the same. The present invention concerns: a method for making a cobalt metal foam catalyst in which a cobalt catalyst powder is coated onto the surface of a metal foam, comprising the steps of: pre-treating the surface of a metal foam by means of the ALD coating method using trimethylaluminium and water for forming an Al2O3 thin film on the metal foam surface; making a cobalt catalyst slurry; surface coating the cobalt catalyst slurry onto the pre-treated metal foam by means of the dip-coating method; and drying and calcining, and the present invention also concerns the cobalt metal foam catalyst, a thermal-medium-circulating heat-exchange reactor, and a method for producing a liquid fuel by means of a Fischer-Tropsch synthesis reaction.
