HYDROCARBON CONVERSION

1402981 Hydrocarbon conversion MOBIL OIL CORP 18 Jan 1974 [9 Feb 1973] 02372/74 Heading C5E Hydrocarbon conversions are carried out using a catalyst comprising a ZSMÀ5 type zeolite defined by X-ray diffraction pattern having an ultimate particle diameter of 0À005- 0À1 Á as crystallized. The catalyst may contain a hydrogenation/dehydrogenation component such as metals, oxides and sulphates of Groups IIB, VIB, VIIB and/or VIII. Examples describe the transalkylation of benzene and diethylbenzene to give ethylbenzene; the alkylation of benzene with ethylene; the alkylation of benzene with n-heptane or n-octane in the presence of hydrogen; the disproportionation of propylene to ethylene and higher olefins; poor point reduction of a gas oil; and cracking a gas oil with a fluidized catalyst.
