摘要/Abstract

摘要： Nano hierarchical mesoporous ZSM-5 catalystswere prepared with cationic dimethyldiallyl ammonium chloride acrylamide copolymer (PDDA) as a soft second template. Using ZSM-5 catalyst as a matrix, Zn/ZSM-5 catalysts were also obtained by the wet impregnation method. The effect of the PDDA amount and Zn loadings on the properties of the catalysts, including crystallinity, morphology, textural properties, acid nature and catalytic activity in MTG reaction, was investigated by XRD, FESEM, TEM, Nitrogen adsorption-desorption isotherms and NH₃-TPD method, respectively. The MTG reaction was performed in a fixed bed reactor, and the result revealed that the nano hierarchical ZSM-5 catalyst prepared with a PDDA/Si molar ratio of 0.070 possesses longer stable phase of 70 h with a liquid hydrocarbon selectivity of 29.8%. Zn/ZSM-5 catalyst with a Zn/ZSM-5 ratio of 0.07 wt.% shows the highest liquid hydrocarbon selectivity, reaching 62.5%.
