Catalytic cracking of palm oil to gasoline over pretreated Cu-ZSM-5

The catalytic conversion of palm oil to gasoline using hydrogen pretreatment onH-ZSM-5 with different copper loadings is discussed in this paper. The Cu-ZSM-5 catalysts were prepared using incipient wetness impregnation technique. The crystallinity, acidity and surface area were examined by X-ray di...
