  • Zeolites as a kind of representative solid acid material, owning unique microporous channels, could be proposed as reasonable candidate muti‐funcational catalysts on oriented synthesis of target products from syngas. This paper represents a novel way for the synthesis of cancrinite zeolite (CAN‐topology) using a solvent‐free strategy. Thus prepared CAN zeolite loaded Co‐based catalyst exhibited a remarkable catalytic performance for direct gasoline synthesis from syngas, producing unexpected gasoline selectivity with 78.3%. The amazing result was attributed to CAN zeolite with a straight channel (12MR, 1‐dimension), leading that Fischer‐Tropsch primary products could continuously and quickly diffuse in its channels. Moreover, a lack of shape selective behavior and weak acidity on CAN zeolite exhibited low isoparaffin selectivity. The Na+ content in CAN zeolite was also an important factor for tuning the product distribution. As expected, the green and facile solvent‐free approach for constructed CAN zeolite will play a vital application in selective conversion of syngas in the future. The product distribution of Fischer‐Tropsch synthesis reaction over Co‐based zeolites is tuned by porous structure of zeolite (dimension and pore size). The CAN‐topology zeolite is first synthesized using a solvent‐free strategy. The amazing gasoline product with the selectivity of 78.3%, has been obtained from Co/NaCAN catalyst, because of CAN zeolite with special 1D pore channel and high Na+ content.
