摘要： Dehydrogenatable hydrocarbons may be subjected to a dehydrogenation reaction in which the hydrocarbons such as ethylbenzene are treated with a dehydrogenation catalyst comprising a modified iron catalyst in the presence of steam. The reaction mixture containing unconverted ethylbenzene, styrene, hydrogen and steam is then contacted with an oxidation catalyst in a second zone whereby hydrogen is selectively oxidized to the substantial exclusion of oxidation of the hydrocarbon. The selective oxidation catalyst which is employed will comprise a noble metal of Group VIII of the Periodic Table, a metal of Group IVA and, if so desired, a metal of Group IA or IIA composited on a porous inorganic support such as alumina. The noble metal of Group VIII of the Periodic Table will be present in the exterior surface of the support which possesses a depth in the range of from about 10 to about 300 microns in an average concentration at least 10% than the Group VIII noble metal average concentration in the core of the support.

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： 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 process for the desulfurization of hydrocarbonaceous oil wherein the hydrocarbonaceous oil is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone to reduce the sulfur level to a relatively low level and then contacting the resulting hydrocarbonaceous stream from the hydrodesulfurization zone with an oxidizing agent to convert the residual, low level of sulfur compounds into sulfur-oxidated compounds. The resulting hydrocarbonaceous oil stream containing the sulfur-oxidated compounds is separated after decomposing any residual oxidizing agent to produce a stream containing the sulfur-oxidated compounds and a hydrocarbonaceous oil stream having a reduced concentration of sulfur-oxidated compounds.
