Steam dehydrocyclization of paraffinic hydrocarbons to aromatic hydrocarbons is effected in the presence of supported catalyst, typically bearing rhodium and preferably chromium and potassium, and characterized by a pH less than about 8.

Dehydrogenation process using a rhodium catalyst

Steam dehydrocyclization of paraffinic hydrocarbons to aromatic hydrocarbons is effected in the presence of catalyst, typically a supported rhodium catalyst bearing copper.

Catalyst for steam dehydrocyclization

Steam regeneration of rhodium containing hydrocarbon dehydrocyclization

Steam dehydrocyclization of paraffinic hydrocarbons in the presence of

Alkylaromatic hydrocarbons are dealkylated in a short cycle process characterized by a reaction period of 30-180 seconds followed by a regeneration period of 90-540 seconds--thus permitting attainment of improved conversion and yield of desired product.

Steam dealkylation process

Dehydrocyclization to aromatic hydrocarbons over rhodium catalyst

Solid fuel is liquefied at elevated temperature and pressure in the presence of a solvent, water and a material which decomposes to carbon monoxide and hydrogen.

Coal liquefaction

A novel active alumina which has been treated with sulfate ion, is found to be particularly characterized by increased performance when used as a support for catalyst which may be used in hydrocarbon conversion processes such as steam dealkylation.

Process for dealkylating an alkylaromatic hydrocarbon using supported

This disclosure is concerned with the use of supported platinum halide, Group IVA metal halide catalysts suitable for the hydroformylation of .alpha.-olefin substrates to predominantly linear, straight-chain aldehydes.

Selective hydroformylation process

Novel method for preparing a high purity alumina

Hydrocarbons are reformed with steam in the presence of, as catalyst, an activated metal screen containing a major portion of nickel. Preferably a non-aromatic hydrocarbon is reacted with steam over inconel metal catalyst at 1200.degree. F-1400.degree. F and 0-300 psig.

Method of steam reforming

Polycyclic aromatic hydrocarbons are treated with steam in the presence of catalyst, typically containing oxides of nickel, potassium, chromium, and aluminum, to form aromatic products containing a lesser number of aromatic rings.

Steam reforming of polycyclic hydrocarbons

Method of producing phenol and cyclohexanone in enhanced yields consisting essentially of contacting cyclohexylbenzene, preferably in the presence of a member selected from the group consisting of cumene and cumene hydroperoxide, with an oxygen containing gas to form 1-phenylcyclohexyl hydroperoxide containing intermediate product, optionally purifying said intermediate, contacting the 1-phenylcyclohexyl hydroperoxide intermediate product with an acid cleavage catalyst in the presence of an alkanone of from 3 to 6 carbons and recovering the formed phenol and cyclohexanone.

Phenol and cyclohexanone manufacture

Methane containing gas is prepared by passing steam and a non-aromatic hydrocarbon into contact with activated metal screen catalyst, such as inconel metal, at about 700.degree.F-1100.degree.F and 300-800 psig.
