Solvent‐Free Synthesis of 1D Cancrinite Zeolite for Unexpectedly Improved Gasoline Selectivity

Abstract

Abstract 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.
