Currently,Fischer-Tropsch synthesis and oxide/zeolite bifunctional catalysis routes can be utilized to produce liquid fuel from syngas.In view of Fischer-Tropsch synthesis route,the product distribution can be regulated through controlling the crystal size,crystal phase structure and metal surface exposure sites of the catalyst.As for bifunctional catalysis route,high selective preparation of liquid fuel can be realized through adding acid catalysis function on Fischer-Tropsch catalyst,or activating C—O bond efficiently to couple with C—C bond accurately.In the future,on the one hand,the main object is to maximize the selectivity of the target products by using new methods in nano-synthetic areas to break the classical ASF distribution,on the other hand,the precise regulation of products selectivity can be realized through carefully designing the active centers of the two-step reaction.
