Patent number: 6103948Abstract: This invention relates to an improved method for the alkylation reaction of isoparaffins with olefins over solid catalysts including contacting a mixture of an isoparaffin, an olefin and a phase-modifying material with a solid acid catalyst member under alkylation conversion conditions at either supercritical fluid, or near-supercritical fluid conditions, at a temperature and a pressure relative to the critical temperature(T.sub.c) and the critical pressure(P.sub.c) of the reaction mixture. The phase-modifying phase-modifying material is employed to promote the reaction's achievement of either a supercritical fluid state or a near-supercritical state while simultaneously allowing for decreased reaction temperature and longer catalyst life.Type: GrantFiled: December 23, 1998Date of Patent: August 15, 2000Assignee: Bechtel BWXT Idaho, LLCInventors: Daniel M.

Patent number: 5986158Abstract: The invention pertains to a process for alkylating hydrocarbons in which an alkylatable organic compound is reacted with an alkylation agent to form an alkylate in the presence of a catalyst comprising a hydrogenating function and a solid acid constituent, with the catalyst being subjected intermittently to a regeneration step by being contacted with a feed containing a saturated hydrocarbon and hydrogen, said regeneration being carried out at 90% or less of the active cycle of the catalyst, with the active cycle of the catalyst being defined as the time from the start of the feeding of the alkylation agent to the moment when 20% of the alkylation agent leaves the catalyst-containing reactor section without being converted, not counting isomerization inside the molecule. The process according to the invention is especially attractive for the alkylation of isobutane with one or more butenes to form an alkylate with a high RON.Type: GrantFiled: November 20, 1997Date of Patent: November 16, 1999Assignee: Akzo Nobel NVInventors: Emanuel Hermanus Van Broekhoven, Francisco Rene Mas Cabre, Pieter Bogaard, Gijsbertus Klaver, Marco Vonhof

Patent number: 5811627Abstract: Improved acid catalyzed alkylation reactions occur for the addition of a hydrocarbyl reactant to an alkene, by the optimized addition of an oxidizing agent, such as a peroxide, molecular oxygen, ozone, peracid, and one or more of the peroxide, molecular oxygen, ozone, or peracid mixed with at least one material selected from the group consisting of the hydrocarbyl reactant, and the alkene. The hydrocarbyl reactant contains at least one tertiary carbon atom attached to hydrogen, such as isobutane. The alkene is preferably an alkene of at least 2 carbon atoms. Suitable peroxides are found in the group consisting of: tert-butyl peroxyneopentanoate ((CH.sub.3).sub.3 C--O--OCO--C(CH.sub.3).sub.3); acetyl peroxide (CH.sub.3 CO--O--OCOCH.sub.3); di-tert-butyl peroxide ((CH.sub.3).sub.3 C--O--O--C(CH.sub.3).sub.3); hydrogen peroxide (H.sub.2 O.sub.2) and peracids of carboxylic acid having up to 10 carbon atoms, and a general chemical formula C.sub.n H.sub.2n O.sub.3, where n has values in the range 2-10.Type: GrantFiled: September 13, 1996Date of Patent: September 22, 1998Inventor: Stanley M.

Patent number: 5779882Abstract: A layered composition of matter, MCM-56, has an X-ray diffraction pattern including lines at d-spacing values of 12.4.+-.0.2, 9.9.+-.0.3, 6.9.+-.0.1, 6.2.+-.0.1, 3.55.+-.0.07 and 3.42.+-.0.07 Angstroms and has been selectively modified so that the ratio of the number of active acid sites at its external surface to the number of internal active acid sites is greater than that of the unmodified material. When used as an additive to a large pore zeolite catalyst in the catalytic cracking of a petroleum feedstock, the modified MCM-56 gives an improved gasoline yield/octane relationship, an improved coke selectivity and a higher combined gasoline and potential alkylate yield than an identical catalyst containing unmodified MCM-56.Type: GrantFiled: July 22, 1996Date of Patent: July 14, 1998Assignee: Mobil Oil CorporationInventors: Arthur W.
