    Abstract: The benzene concentration in the gasoline pool of a petroleum refinery is decreased by alkylation of the benzene in a catalytic dewaxing reactor using the olefinic by-products from the dewaxing reaction as alkylating agents. The catalytic dewaxing is preferably carried out in the presence of an intermediate pore size zeolite such as ZSM-5 using a distillate or lube boiling range dewaxing feed. The benzene rich feed preferably contains less than about 2 % C7+ aromatics in order to reduce alkylation of non-objectionable species in the reformate.

    Abstract: Vanadium in marine diesel lubricating oils resulting from raw fuel dilution is detected and quantified by means of an analytical technique employing electron spin resonance (ESR). Dilution of the lubricating oil with residual fuel oils results in the presence of vanadium in the lubricating oil in a form which is capable of being observed by ESR; by contrast, vanadium resulting from the presence of fuel oil combustion products (pentavalent vanadium) in the lubricating oil is not observed by ESR. The method therefore enables fuel vanadium, typically present as vanadyl porphyrins, to be differentiated from vanadium resulting from blow-by in the engine so that the operating condition of the engine may be monitored.

    Abstract: A method for determining a propped fracture's (28) height (32) and width (30) wherein acoustic logging devices are used in a borehole. Compressional and shear wave velocities obtained by transmitting acoustic energy through the borehole (12) and into the formation are made at a plurality of locations before and after fracturing the formation. In-situ stresses are determined at the plurality of locations before and after fracturing the formation from velocities of the compressional and shear waves which were detecte before and after fracturing the formation. Differences between in-situ stresses obtained at each of said locations before and after fracturing the formation are used to predict a height and width of a propped fracture.

    Abstract: The zeolite ZSM-12 is synthesized by crystallizing a reaction mixture comprising sources of alkali or alkaline earth metal (M), an oxide of trivalent element (X), an oxide of tetravalent element (Y), water and hexamethyleneimine directing agent (R), and having a composition, in terms of mole ratios, within the following ranges: YO2/X2O3 60 to >2000; H2O/YO2 5 to 200; OH-/YO2 0.1 to 0.4; M/YO2 0.05 to 1.0; R/YO2 0.1 to 1.0. Crystallization is effected by maintaining the mixture at a temperature of 120 °C to 210 °C for 24 hours to 10 days.

    Abstract: A process for production of ether by catalytic hydration and etherification of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a plurality of catalytic reaction zones containing porous solid metal oxide acidic olefin hydration and etherification catalyst under hydration and etherification conditions. Improved operation is achieved by recovering a first effluent stream from at least one fixed bed hydration zone; splitting the first effluent stream into a product recovery stream and a plurality of recycle streams; and passing at least a portion of cooled recycle streams comprising olefin, alcohol and ether in effluent stream component proportions for quenching at least one fixed bed reaction zone along with hot effluent from a preceding reaction zone.

    Abstract: A process and apparatus (Figs. 1, 2, 3 and 4) for controlled, multi-stage regeneration of FCC catalyst is disclosed. A modified high-efficiency catalyst regenerator (80), with a fast fluidized bed coke combustor (62), dilute phase transport riser (83), and second fluidized bed (82) regenerates the catalyst in at least two stages. The primary stage of regeneration is in the coke combustor (62). Second stage catalyst regeneration occurs in the second fluidized bed (82). The amount of combustion air added to both regeneration stages is set to maintain partial CO combustion in both stages. Controlled multi-stage regeneration reduces the steaming or deactivation of catalyst during regeneration, maximizes coke burning capacity of the regenerator (80), and minimizes or eliminates NOx emissions.

    Abstract: A process and apparatus for controlled, multi-stage, regeneration of FCC catalyst is disclosed. A modified high efficiency catalyst regenerator, with a fast fluidized bed coke combustor, dilute phase transport riser, and second fluidized bed regenerates the catalyst in at least two zones, both operating with complete CO combustion. The primary stage of regeneration is in the coke combustor. Second stage catalyst regeneration occurs in the second fluidized bed. The amount of combustion gas, and/or the feed rate, feed preheat, catalyst recirculation to the coke combustor and rate of CO oxidation promoter addition are controlled to maintain complete CO combustion in both zones. Controlled multi-stage regeneration reduces the steaming or deactivation of catalyst during regeneration, increases coke burning capacity of the regenerator, and maximizes efficiency of SOx getters.
