Patent number: 4676885Abstract: The invention disclosed herein comprises a process for the selective upgrading of combustion quality of a distillate transportation fuel by careful selective dehydrogenation, disproportionation and hydrogenation to convert cycloparaffinic materials contained in the distillate transportation fuel to acyclic paraffinic hydrocarbons, wherein said conversion is undertaken by first forming cyclomonoolefinic hydrocarbons from cycloparaffinic hydrocarbons via dehydrogenation, disproportionating the cyclomonoolefinic hydrocarbons to acyclic di-.alpha.-olefin hydrocarbons and then selectively hydrogenating said di-.alpha.-olefin hydrocarbons in the presence of hydrogen to saturate the double bonds of the di-.alpha.-olefin to form acyclic paraffinic hydrocarbons. The selective disproportionation reaction includes the addition of ethylene or an ethylene acting material to ring open the cyclomonoolefinic material.Type: GrantFiled: May 28, 1986Date of Patent: June 30, 1987Assignee: Shell Oil CompanyInventor: Warren V.
