International Classification:
C07C 2/86
US Classification:
585321, 585322
Abstract:
In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of Cto Colefinic and aromatic hydrocarbons is recovered from the first stream and at least part of the second stream is contacted with a catalyst in the absence of added hydrogen under reaction conditions including a temperature of about 450° C. to about 70° C. effective to dealkylate, transalkylate, crack and aromatize components of the second stream to produce a third stream having an increased benzene and/or toluene content compared with the second stream and a C− olefin by-product. The C− olefin by-product and a fourth stream comprising toluene are then recovered from the third stream.

International Classification:
C07C 4/02, C07C 5/32, C07C 5/333, B01J 8/00
US Classification:
585322, 422635, 422643, 585324, 585326
Abstract:
A reverse flow regenerative reactor having first and second zones, each having first and second ends, the first zone having a plurality of channels capable of separately conveying at least two components of a combustible gas mixture, a gas distributor configured for injecting the components of the combustible gas mixture into first zone, a combustion zone including a selective combustion catalyst disposed at or downstream of the second end of said channels for catalyzing combustion, wherein the second zone is positioned and situated to receive a combusted gas mixture. Processes usefully conducted in the reactor are also disclosed.

International Classification:
C07C 2/64
US Classification:
585321, 585319
Abstract:
In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of Cto C+ olefinic and aromatic hydrocarbons is recovered from the first stream and blended said second stream with a residual fraction from a steam cracker or an atmospheric or vacuum distillation unit to produce a third stream. The third stream is then catalytically pyrolyzed in a reactor under conditions effective to produce a fourth stream having an increased benzene and/or toluene content compared with said second stream and a C-olefin by-product. The C-olefin by-product is recovered and benzene and/or toluene are recovered from the fourth stream.

US Classification:
423278, 705500, 423635, 422600, 422625
Abstract:
The present application is directed to a method and system for monetizing energy. More specifically, the invention is directed to the economically efficient utilization of remote or stranded natural gas resources. The invention includes importing a high energy density material into an energy market and distributing the high energy density material (HEDM) therein. The HEDM is produced from reduction of a material oxide such as boria into the HEDM, which may be boron. The reduction utilizes remote hydrocarbon resources such as stranded natural gas resources.
