Abstract

<p>Into a zeolite-Al2O3 composite prepared by the kneading method was supported Pt using the impregnation method. The catalyst obtained was used for hydrocracking of n-heptadecane to produce jet fuel. 0.5Pt/Y(100)35A, where 0.5 means wt% of Pt, Y means zeolite type, 100 in a parenthesis means SiO2/Al2O3 ratio and 35 means wt% of Al2O3, exhibited the high selectivity for jet fuel of 74%, the conversion of 99% and the high yield of jet fuel of 73% at 295℃. In contrast to this, 0.5Pt/Z(110)35A, where 0.5 means wt% of Pt, Z means ZSM-5 zeolite, 110 in a parenthesis means SiO2/Al2O3 ratio and 35 means wt% of Al2O3, exhibited the increase in gaseous products, the low selectivity for jet fuel of 22%, the conversion of 97% and the low yield of jet fuel of 21% at 270℃.</p>
