Process for oxidative dehydrogenation of paraffinic lower hydrocarbons

摘要

The present invention relates to a process for producing lower olefinic hydrocarbons by oxidative dehydrogenation of paraffinic lower hydrocarbons. More particularly the present invention provides a process for converting a feedstream comprising a paraffinic lower hydrocarbon and carbon dioxide to a product stream comprising an olefinic lower hydrocarbon and synthesis gas in the presence of the catalyst composition La—Mn/inert support, wherein said catalyst composition comprises 1-10 mass % lanthanum and 1-10 mass % manganese and optionally 0.3-3 mass % alkali metal.

1. Process for converting a feedstream, said process comprising:
contacting the feedstream comprising a paraffinic lower hydrocarbon and carbon dioxide with a reduced catalyst composition on an inert support, wherein said catalyst composition comprises 1-10 mass % reduced La (lanthanum) metal and 1-10 mass % reduced Mn (manganese) metal, to produce a product stream comprising an olefinic lower hydrocarbon and synthesis gas, wherein the paraffinic lower hydrocarbon to carbon dioxide ratio is in the range of about 0.7 to 1.
