摘要:
A novel integrated olefin processing scheme is provided where olefins and paraffins are processed to produce high octane gasoline blending components. The integrated process involves the processing of olefins by hydroisomerization to produce a hydroisomerate stream which is subsequently alkylated in an alkylation process with branched chain paraffin hydrocarbons to produce an alkylate product. The alkylate product can further be separated into various fractions, including propane, n-butane, i-butane and a C 5 + alkylate stream. The C 5 + alkylate stream can be separated into an i-pentane stream and a deisopentanized C 5 + alkylate stream.
摘要:
A method of preparing a catalyst system which comprises mixing a first solid material comprising at least one perfluoroalkylsulfonic acid salt with a second solid material comprising at least one silanol comprising hydroxy groups and silicon to form a gel comprising silica and the at least one perfluororalkylsulfonic acid salt, and contacting the gel with an acidic solution to convert at least a portion of the at least one perfluoroalkylsulfonic acid salt to at least one perfluoroalkylsulfonic acid is disclosed. Alternatively, a method of preparing a catalyst system which comprises mixing at least one perfluoroalkylsulfonic acid salt with silica gel to form a gel comprising silica and at least one perfluororalkylsulfonic acid salt, and contacting the gel with an acidic solution to convert at least a portion of the at least one perfluororalkylsulfonic acid salt to at least one perfluororalkylsulfonic acid is disclosed. The thus-obtained catalyst systems are employed as catalysts in the oligomerization of a hydrocarbon feedstock comprising unsaturated hydrocarbons.

摘要:
A novel i-pentane disproportionation process is provided and includes contacting i-pentane with an acidic disproportionation catalyst in the presence of a lower paraffin co-feed and, optionally, in the presence of an initiator.
摘要:
A process for the disproportionation of pentane to alkanes containing fewer carbon atoms per molecule and alkanes containing more atoms per molecule in the presence of a catalyst composition containing hydrogen fluoride (HF), titanium tetrafluoride (TiF 4 ) and sulfolane.
摘要:
Described is a novel process for regenerating an ASO contaminated alkylation catalyst which contains a sulfone component and a hydrogen halide component. The alkylation catalyst undergoes a series of separation steps to remove a significant portion of the hydrogen halide component contained therein followed by a phase separation between an ASO phase and a sulfone phase. The sulfone phase is then contacted with a carbon material to remove a portion of any remaining ASO contained in the sulfone.
