摘要： Hydrogen sulfide can be conveniently removed from streams containing up to about 1,000 ppm of H.sub.2 S by reacting the latter with an olefin using a bed of an acidic solid catalyst in a non-oxidative process for the removal of hydrogen sulfide. The reaction can be effected under relatively mild conditions and is very selective for the removal of hydrogen sulfide without being attended by other unwanted reactions such as oligomerization, disproportionation, and skeletal rearrangement. Levels of hydrogen sulfide in the treated product of no more than about 5 ppm can be readily attained using a broad variety of acidic solid catalysts and unsaturated hydrocarbons, especially olefins.

摘要： Olefinic feedstocks which contain catalyst contaminants or poisons such as sulfur-containing compounds may be oligomerized to a desired oligomer and configuration of the oligomer by utilizing a catalyst which is stable and will not deactivate due to the presence of the aforementioned poisons. The catalyst comprises a porous support which has been impregnated with a catalytically effective amount of an iron group metal compound and a Group IVA metal compound. In addition, the catalyst composite may also contain in combination therewith, a catalytically effective amount of an alkyl aluminum compound and an aluminum alkoxy/aluminum halide compound.

摘要： Unsaturated hydrocarbons may be prepared by subjecting a dehydrogenatable hydrocarbon to dehydrogenation in the presence of a dehydrogenation catalyst. The effluent stream from this step, comprising unconverted hydrocarbons, dehydrogenated hydrocarbons, hydrogen and steam, may then be passed to a selective oxidation step in which the hydrogen is selectively oxidized in the presence of an oxygen-containing gas to the substantial exclusion of the oxidation of the hydrocarbons. The oxidation catalyst which is employed will comprise a Group VIII noble metal, a Group IVA metal and a Group IA or IIA metal composited on a metal oxide support. The metal oxide support such as alumina will possess a particular configuration having one or more open channels such as a tubular or cartwheel particle having an outside to inside diameter ratio of the channels ranging from 1.1 to 8 and having a ratio of shape surface to catalyst volume greater than [4D+2L] in which D is the largest representative diameter of the particle and L is the length of the particle.

摘要： A hydrocarbon conversion process is disclosed for the production of lower alcohols and LPG from a mixture of C.sub.3 -minus paraffins and olefins. The feed stream is passed into a hydration zone wherein portions of the ethylene and propylene are converted to ethanol and propanol. The hydrocarbons which are not hydrated are passed into a hydrogenation zone wherein the remaining olefins are converted to paraffins. The feed stream is preferably a hydrogen-containing C.sub.1 to C.sub.3 cut separated from the effluent of a fluidized catalytic cracking unit.

摘要： Olefinic hydrocarbons which contain from three to about six carbon atoms may be subjected to oligomerization reactions as well as being used as alkylating agents in the alkylation of alkylatable hydrocarbons by treatment at reaction conditions in the presence of a catalyst comprising a phosphorus fluoride such as phosphorus trifluoride or phosphorus pentafluoride composited on a high surface area metal oxide such as gamma-alumina. The oligomers which are obtained in the oligomerization process will contain less branching than those which are obtained when utilizing other catalysts.
