摘要:
In a process for isomerizing monoolefins having a terminal double bond (in particular the isomerization of butene-1 to butene-2) in the presence of a Group VIII metal catalyst (in particular an alumina-supported Pd catalyst) which is contaminated by impurities in the monoolefin containing feed, the improvement comprises pretreating the feed with a solid material comprising tin oxide and a refractory support material (in particular alumina).
摘要:
A catalyst and process for the selective hydrogenation of acetylene, said catalyst comprising palladium and silver with the palladium concentrated as a skin and the silver distributed throughout.
摘要:
Synthesis of ammonia employing at least one salt selected from alkali metal-, an alkaline earth metal-, iron- and cobalt hexacyanocobaltate and hexacyanoruthenate on a suitable support and then heating the composition to provide it with suitable activity.
摘要:
Organic hydroperoxides are prepared by reacting an organic compound with oxygen in the presence of a novel catalyst comprising metallic silver supported upon an inorganic support selected from the oxides and carbonates of metals of Groups IIa, IIb, IIIb, and IVb.
摘要:
A method and catalysts for selective hydrogenation and isomerization which involves contacting a feedstream with hydrogen and with various supported catalysts of metallic arsenides and antimonides, with carbon monoxide being optionally introduced into the reaction as a modifier.
摘要:
A catalyst consisting essentially of nickel, a promoter selected from the group consisting of barium and uranium and a calcium phosphate support having a Ca:P atomic ratio in the range of 1.4:1 to 2.3:1, is formed by impregnating a calcium phosphate gel with suitable compounds of nickel and either barium or uranium. The resulting catalysts are useful in steam reforming processes for producing methane.
摘要:
Complexing reagents are provided which comprise Cu(I) carboxylates or Cu(I) sulfonates and high molecular weight olefins. The invention complexing reagents are useful for separating olefins from mixtures of olefins and paraffins.
摘要:
