摘要:
Aromatic hydrocarbons are alkylated with relatively long chain alkylating agents, e.g., C.sub.6 + olefins, in the presence of, as catalyst, certain Lewis acid-promoted zeolites to provide long chain aromatic products which are useful, inter alia, as lubricating oil stocks.

摘要:
An improved continuous process for alkylation of isoparaffins with olefins to yield a product which includes a large proportion of highly branced paraffins for making gasoline having improved octane is taught. The improved process comprises contacting isoparaffins and olefins with a composite catalyst comprising a Lewis acid and a non-zeolitic inorganic oxide in the presence of a controlled amount of water. The process results in reduced catalyst aging and obviates environmental problems associated with prior art processes.
摘要:
A method for upgrading an aromatics-containing charge composition boiling in the gasoline boiling range comprises i) contacting the charge composition with a nitrating agent under nitrating conditions to form a product comprising nitrated aromatics; ii) hydrogenating a feed containing the product of i) under conditions sufficient to substantially reduce the nitro group of the nitrated aromatics so as to form a product comprising aromatic amines, water and heavy amines; and iii) removing the water and heavy amines from the product of step ii) to provide a gasoline boiling range product of an octane rating greater than the charge composition.

摘要:
A process is disclosed for upgrading C.sub.5 -C.sub.8 olefin-containing gasoline to a high octane motor gasoline blending component.C.sub.3 -C.sub.4 olefins are hydrated to alcohols and then selectively removed from the aqueous hydration reactor effluent stream via liquid extraction with the gasoline feedstream. The alcohol enriched gasoline extract stream is then etherified and unreacted alcohols are extracted to yield a high octane gasoline blending component free of metal-bearing additives.
