There is provided a catalyst comprising nickel supported on a pillared (e.g., silica pillared) vacancy titanate material. There is also provided a method for preparing this catalyst. This method may involve impregnating a pillared vacancy titanate material with a nickel nitrate solution. There is further provided a process for oligomerizing ethylene using this catalyst.

Oligomerization of ethylene with a supported nickel catalyst

A process and catalyst for catalytic cracking comprising a non-layered, ultra-large pore crystalline material. The crystalline material preferably has a benzene adsorption capacity greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C. Preferred materials have a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units. Preferred cracking catalysts comprise ultra-large pore materials having pore openings formed by at least 20 tetrahedrally coordinated members, most preferably with 36 or 42 tetahedrally coordinated members.

There is provided a method for the removal of residual organic swelling agent from pillared layered materials by treating such materials with acid.

A layered product comprises a layered metal oxide and pillars of an oxide of at least one element selected from Groups IB, IIB, IIIA, IIIB, IVA, IVB, VA, VB, VIA, VIIA and VIIIA of the Periodic Table of the Elements separating the layers of the metal oxide. Each layer of the metal oxide has the general formula

Layered metal oxides containing interlayer oxides and their synthesis

There is provided a sulfated layered titanium oxide catalyst. Relatively long chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a relatively long chain alkylating agent under alkylation reaction conditions in the presence of this sulfated layered material as alkylation catalyst. The layered material contains titanium oxide in the layers and oxide pillars separating the layers. The alkylation activity of the catalyst is increased by including sulfate ions in the layered material. This increased alkylation activity may be obtained by contacting the layered material with an aqueous solution of a sulfate compound such as sulfuric acid.

Relatively long chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a relatively long chain alkylating agent under alkylation reaction conditions in the presence of a layered material as an alkylation catalyst. The layered material contains titanate in the layers and oxide pillars separating the layers. The layers also contain vacancies and/or metals incorporated therein. The degree of alkylation is a function of the interplanar d-spacing of the pillared material, which is, in turn a function of the chain length of the swelling agent used to prepare the layered material.

Process for preparing long chain alkyl aromatic compounds

Ternary oxide phases, including copper oxide, which exhibit unusal electronic properties, have been determined to exhibit catalytic function for the oxidiation of carbon monoxide, the hydrogenation of ethylene and the cracking of hydrocarbons.

Crystalline oxides as catalysts

Perovskite related materials of high thermal stability and surface area which contain interspathic polymeric chalcogenides such as polymeric silica are prepared by ion exchanging a layered metal oxide, such as layered titanium oxide, with organic cation, to spread the layers apart. A compound such as tetraethylorthosilicate, capable of forming a polymeric oxide, is thereafter introduced between the layers. The resulting product is treated to form polymeric oxide, e.g. by hydrolysis, to produce the layered oxide material. The resulting product may be employed as catalyst material in the conversion of organic compounds.

Organic-swelled layered metal chalcogenide is intercalated with polymeric chalcogenide by contacting with a hydrolyzable polymeric chalcogenide precursor under an inert atmosphere, e.g., nitrogen to minimize formation of extralaminar polymeric chalcogenide. The chalcogenide precursor is then hydrolyzed.
