摘要： The invention here disclosed is a process for the selective removal of H.sub.2 S and COS from a gas stream having a relatively large concentration of CO.sub.2 and being predominantly formed of light hydrocarbons, such as methane. This process provides for the selective solvent extraction of H.sub.2 S and COS without absorbing CO.sub.2. In this process, the solvent comprises a bridgehead amine, a tertiary amine, water, and optionally a physical solvent acceptable to COS absorption, such as sulfolane. The absorption conditions of this process comprise a pressure of from about atmospheric to about 1200 psig and a temperature of from about 40.degree. F. to about 250.degree. F. The treated stream derived from this process contains CO.sub.2 and light hydrocarbons and a near absence of H.sub.2 S and COS.

摘要： 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. The reaction may be undertaken in either a single stage vessel, or in a three stage vessel having three unitary reaction areas comprising first, a dehydrogenation zone, second, a disproportionation zone and third, a hydrogenation zone.
