摘要:
A process for hydrogenating an unsaturated organic compound which comprises contacting the same with hydrogen in the presence of a catalyst composed of a support containing (1) (A) a Group IIB metal compound selected from the group consisting of zinc and cadmium compounds, (B) a combination of said zinc and cadmium compounds or (C) a combination of at least one of said Group IIB metal compounds with at least one Group IIA metal compound selected from the group consisting of magnesium, calcium, strontium and barium compounds, (2) alumina and (3) aluminum phosphate and carrying nickel thereon.
摘要:
Spent boron trifluoride catalyst is removed from organic liquids by contacting the liquid with polyvinyl alcohol. For example, boron trifluoride catalyst is removed from 1-olefin oligomer product by passing the liquid oligomer through a bed of granular polyvinyl alcohol. The boron trifluoride is recovered from the polyvinyl alcohol and is recycled for use as a catalyst.

A process for hydrogenating an unsaturated organic compound which comprises contacting the same with hydrogen in the presence of a catalyst composed of a support containing (1) at least one Group IIA metal compound selected from the group consisting of magnesium, calcium, strontium and barium compounds, (2) alumina and (3) aluminum phosphate carrying nickel thereon.
摘要:
An integrated in situ combustion process for producing subterranean carbonaceous deposits in which the resulting flue gas of low heating value is combusted over an oxidation catalyst at substoichiometric conditions and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit. An oxidation catalyst is provided for reducing carbon monoxide in the combusted flue gas comprising platinum and at least one metal cocatalyst selected from Groups IA, II, III, VIIB and VIII up through atomic No. 45, the lanthanides, chromium, silver, tin and antimony.
摘要:
The amount of oxygen-containing impurities in an organic composition is reduced at an elevated temperature by contact with a supported metal oxide. For example, the amount of oxygen-containing organic impurities in a crude stilbene product obtained by oxidatively dehydrocoupling toluene using a solid oxidant is decreased by contact with zinc oxide supported on alumina at an elevated temperature and the resulting purified stilbene product is reacted with ethylene to form styrene.
摘要:
The amount of oxygen-containing impurities in an organic composition is reduced at an elevated temperature in the presence of steam using a catalyst comprising a Group VIb or Group VIII metal oxide or phosphate. For example, the amount of oxygen-containing organic impurities in a crude stilbene product obtained by the oxidative dehydrocoupling of toluene is catalytically reduced at high temperatures in the presence of steam and an iron oxide catalyst and the resulting stilbene product is reacted with ethylene to form styrene.

摘要:
An integrated in situ combustion process for recovering subterranean liquid and solid carbonaceous deposits in which the resulting flue gas of low heating value is combusted at substoichiometric conditions over two different oxidation catalysts in two combustion zones in series and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit. One of the oxidation catalysts comprising platinum and at least one metal cocatalyst selected from Groups IIA and VIIB, Group VIII up through atomic No. 45, the lanthanides, chromium, zinc, silver, tin and antimony is provided to reduce the carbon monoxide in the combusted flue gas.
摘要:
A catalyst comprising (1) a subgroup of a certain class of nickel and/or cobalt-substituted semicrystalline aluminosilicates which are synthetic and which are predominantly ordered in two directions (laminar clay-like materials); (2) tungsten in the form of its oxide and/or sulfide; and (3) a crystalline zeolite which has an alpha value of at least 20, which is in particulate form, and which is dispersed through the layered aluminosilicate; and processes using this catalyst.
摘要:
An improved process has been discovered for hydrodenitrification of high nitrogen content charge stocks by effecting the nitrogen removal in the presence of a non-zeolitic catalyst consisting essentially of a nickel and/or cobalt substituted synthetic mica-montmorillonite having dispersed therein tungsten in the form of its oxide and/or sulfide.
