The specific surface area of compounds (I), (VI), (XI), (XIII), (XIV)and (XV) are 1-100 m2/g, preferably 50-100 m2/g. The specific surface area of compounds (II), (III), (IV), (V), (VII), (VIII), (IX), (X), (XII), (XVI), and (XVII) are 5-150 m2/g, preferably 50-150 m2/g. The specific surface area of micropores in the MCM-22 molecular sieve accounts for 70-100% of the total specific surface area of the molecular sieve. x = 0.7-3.7; a = 0-1;and a+b = 0-1. An INDEPENDENT CLAIM is included for a method for direct conversion of syngas to liquid fuel, involving using syngas as reaction raw material to carry out the conversion reaction in a fixed bed or a moving bed, and using the catalyst.
