Effect of phosphorous and impregnation method on Propylene selectivity from methanol over HZSM-5 nano catalysts

Effect of the modified zeolites with different amount of phosphorous (P/HZSM-5) on catalytic performance for the methanol to propylne (MTP) process was investigated. The modification of catalysts were carried out by wet impregnation and dry impregnation methods and the effect ofthat objects were studied on the catalytic performance of HZSM-5 (SiO2/Al2O3=100) zeolites inMTP process. The investigation of product distribution showed that the selectivity to propylenedecreased with increasing phosphorous content. The higher propylene selectivity achieved withdry impregnation method.
