Abstract:
Alkenes and/or alkadienes are contacted with molecular oxygen and an oxidative dehydrogenation catalyst consisting essentially of phosphorus, iron, and oxygen, with the iron-to-phosphorus atom ratio being in the range of about 2:1 to about 20:1.
Abstract:
Alkenes and/or alkadienes are contacted with molecular oxygen and an oxidative dehydrogenation catalyst consisting essentially of molybdenum, vanadium, oxygen, and at least one promoter selected from the group consisting of iron, cobalt, and nickel, to produce furan compounds.
Abstract:
Alkenes and/or alkadienes are contacted with molecular oxygen and an oxidative dehydrogenation catalyst consisting essentially of phosphorus, vanadium, and oxygen, wherein the vanadium-tophosphorus atom ratio is in the range of about 2:1 to about 12:1, to produce furan compounds.
Abstract:
Compositions comprising Fe/P/Group IIIA components are effective as catalysts in processes to convert organic compounds to compounds having a greater degree of unsaturation.

Abstract:
A two-stage reforming process for the production of high-octane unleaded motor fuel from low-octane naphthas. The paraffinic raffinate from an intermediate extractive distillation step is reformed over a steam-active catalyst. Several product streams produced during the various process steps are combined to produce a high-octane motor fuel.
Abstract:
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.
Abstract:
A highly active catalyst suitable forthe polymerization of olefins and its use are disclosed, said catalyst being prepared by(1) co-comminuting an aluminum halide; at least one electron donor; a Group IVB-VIB transition metal compound; and a support base selected from the group consisting of the Group IIA and IIIA salts and the salts of the multivalent metals of the first transition series with the exception of copper to produce a coground solid;(2) extracting said coground solid with an organic liquid; and(3) separating the solid from the liquid under such conditions that at least 5 weight percent of the aluminum in the coground solid is removed.
