Abstract: A method for preparing liquid fuel by direct conversion of syngas uses the syngas as reaction raw material and conducts a catalytic conversion reaction on a fixed bed or a moving bed. The catalyst is a composite catalyst formed by compounding component I and component II in a mechanical mixing mode. The active ingredient of the component I is a metal oxide, and the component II is at least one of zeolites with one-dimensional ten-membered ring porous channels; and a weight ratio of the active ingredient in the component I to that in the component II is 0.1-20. The reaction process has high product yield and selectivity. The selectivity for liquid fuel composed of C5-C11 can reach 50-80%. The selectivity for aromatic hydrocarbon is less than 40% in C5-C11, while the selectivity for methane side product is less than 15%.

Abstract: A method of making an active catalyst composition includes mixing an alumina support with first catalyst precursor particles and grinding thereby at least partially embedding the first catalyst precursor particles onto surfaces of the alumina support to form a first composite precursor; mixing the first composite precursor and a first solvent to form a first mixture; grinding the first mixture and drying at a temperature of 100 to 150° C.; calcining the first mixture after the drying at a first temperature of at least 200° C. and a second temperature of at least 550° C. thereby allowing the first catalyst precursor particles embedded onto the surfaces of the alumina support to decompose in situ to generate first catalyst particles embedded onto the surfaces of the alumina support and form a first catalyst; and mixing the first catalyst with a second catalyst to form the active catalyst composition.
