The present invention relates to a process for the production of ethylbenzene from dilute ethylene streams, especially from mixtures of ethane and ethylene where such mixture is the offgas from a refinery operation, such as a fluid catalytic cracking (FCC) operation and wherein the unreacted ethane from the alkylation reactor is dehydrogenated to produce ethylene which is recycled into the original dilute ethylene stream.

An improved multistage ethylbenzene dehydrogenation process comprising feeding steam and a major fraction of a hydrocarbon feed to a first reactor and feeding a remaining minor fraction of the hydrocarbon feed and a product of the first reactor to a second reactor.

Catalyst activity life of an iron oxide-containing catalyst is extended by contacting such catalyst with a feedstream containing about 0.0001 to about 0.01 mole of oxygen per mole of feed in the substantial absence of an oxidation catalyst.

Hydrocarbon conversion catalyst system and method

A method for hydroconversion of coal solids in a solvent by contact with molecular hydrogen and catalyst solids in a reactor. The catalyst solids are catalytically active substances including promoted or unpromoted molybdenum on an alumina support material. The support is characterized by bimodal pore distribution with the average diameter of the smaller pores ranging from about 100-200 angstroms and preferably 120-140 angstroms, and average diameter of the larger pores being in excess of 1,000 angstroms.

Disclosed is a catalyst essentially free of platinum, comprising from about 0.1 to about 2 weight percent rhenium and about 0.1 to about 2 weight percent gallium supported on a solid inorganic refractory oxide. A hydrocarbon conversion process, such as catalytic reforming, is also disclosed wherein the process contacts the above described catalyst with a hydrocarbon stream boiling in the range of about 70.degree. F. to about 500.degree. F. and hydrogen. A two-step process is also disclosed wherein a platinum catalyst is first contacted with a hydrocarbon stream to achieve a partial conversion followed by contacting the above described catalyst to achieve further conversion.

Catalyst and hydrocarbon conversion process

The catalyst comprises a Group-VIII-noble-metal hydrogenation component and a small amount of zirconium on a solid catalytic support comprising a porous refractory inorganic oxide. The zirconium may be present either in the elemental form or as compounds. The preferred hydrogenation component is platinum and the preferred porous refractory inorganic oxide is a catalytically active alumina. The reforming process comprises contacting a petroleum hydrocarbon stream in a reforming zone under reforming conditions and in the presence of hydrogen with the above-described catalyst. In one embodiment, the process comprises contacting a partially-reformed hydrocarbon stream in a reforming zone under reforming conditions and in the presence of hydrogen with the above catalyst. In another embodiment, the process comprises contacting a naphtha in a reforming zone under reforming conditions and in the presence of hydrogen with the above catalyst. In a third embodiment, the process comprises contacting the petroleum hydrocarbon stream in a first reforming zone under reforming conditions and in the presence of hydrogen with a first reforming catalyst to produce a first reformate and subsequently contacting the first reformate in a second reforming zone under reforming conditions and in the presence of hydrogen with a second reforming catalyst, said second reforming catalyst being the catalyst described in the preceding paragraph.
