Fine, pure, boehmite alumina crystallites are peptized, partially precipitated and phosphated, hardened, and dried to form a xerogel. The alumina can be impregnated with a chromium compound. The chromium-containing catalyst is activated by calcination. The activated catalyst can be used as a polymerization catalyst to polymerize mono-1-olefins.

Peptized and phosphated inorganic oxides, catalysts, and polymerization

A catalyst composition comprises (a) alumina, (b) zinc titanate, (c) at least one compound of molybdenum, (d) at least one compound of at least one of nickel and cobalt, and (e) at least one compound of rhenium. This catalyst composition is used for hydrotreating a liquid hydrocarbon-containing feed stream, which contains organic compounds of sulfur, nitrogen and oxygen under such conditions as to obtain a product having reduced levels of sulfur, nitrogen and oxygen. Preferably the hydrocarbon-containing feed stream contains cycloalkanes, which are at least partially reformed to aromatic compounds.

Hydrotreating process employing a novel catalytic composition

The removal of sulfur oxide (particularly sulfur dioxide) from a fluid stream, such as the tail gas from a sulfur process, is accomplished by contacting such fluid stream with a catalyst composition comprising zinc titanate and a promoter in the presence of a hydrogen donor.

Removal of sulfur oxides from fluid streams

The formation of carbon on metals exposed to hydrocarbons in a thermal cracking process is reduced by contacting such metals with an antifoulant selected from the group consisting of tin, a combination of tin and antimony, a combination of germanium and antimony, a combination of tin and germanium and a combination of tin, antimony and germanium.

Antifoulants for thermal cracking processes

The catalytic hydrodenitrogenation of organic compounds containing sulfur and/or nitrogen is carried out in the presence of a catalyst composition comprising zinc titanate and at least one promoter selected from the group consisting of vanadium, chromium, cobalt, nickel, molybdenum, tungsten, rhenium, platinum, palladium, rhodium, ruthenium, and compounds thereof.

Catalytic hydrodenitrogenation of organic compounds employing promoted

The catalytic hydrodesulfurization of organic compounds containing sulfur is carried out in the presence of a catalyst composition comprising zinc titanate and at least one promoter selected from the group consisting of vanadium, chromium, cobalt, nickel, molybdenum, tungsten, rhenium, platinum, palladium, rhodium, ruthenium, and compounds thereof.

Catalytic hydrodesulfurization of organic compounds employing promoted

Hydrogen sulfide is removed from a fluid stream by contacting the fluid stream which contains hydrogen sulfide with an absorbing composition comprising zinc, titanium and at least one promoter selected from the group consisting of vanadium, chromium, manganese, iron, cobalt, nickel, molybdenum, rhenium, and compounds thereof. If organic sulfur compounds are present in the fluid stream, the absorbing composition acts as a hydrodesulfurization catalyst to convert the sulfur in the organic sulfur compounds to hydrogen sulfide which is subsequently removed from the fluid stream by the absorbing composition. If olefin contaminants are present in the fluid stream, the absorbing composition acts as hydrogenation catalyst to hydrogenate the olefin contaminants to paraffins.
