  • Patent number: 5395513
    Abstract: A continuous process for upgrading reformate feedstock or the like to reduce benzene content and increase octane fuel rating. The improved process comprises maintaining a fluidized bed of regenerable acid solid medium pore zeolite catalyst particles in a turbulent regime reaction zone, preferably maintained with a superficial gas velocity of 0.1 to 1 meter/sec. with reformate feedstock being introduced at a bottom portion of the reaction zone at a weight hourly space velocity (WHSV) of 0.1 to 5, based on active catalyst solids; reaction zone total pressure being less than 2000 kPa. The preferred catalyst particles have an average particle size of 20 to 100 microns (.mu.), with about 10 to 25% of the catalyst particles comprising fine particles having a particle size less than 30 microns; and the preferred zeolite catalyst comprises shape selective medium pore aluminosilicate zeolite having a constraint index of 1 to 12. The benzene is reacted by contacting reformate feedstock, such as C.sub.

  • Patent number: 5378671
    Abstract: There is provided a method for preparing an alumina bound, zeolite catalyst, wherein a zeolite of low silanol content is used as the source of zeolite used to prepare the catalyst. A particular zeolite used in this catalyst is zeolite Y. This catalyst may be combined with at least one hydrogenation component and used to hydrocrack hydrocarbons, such as gas oils. In particular, an NiW/USY/alumina catalyst may be used in a hydrocracking reaction to produce distillate boiling range hydrocarbons from higher boiling hydrocarbons.

  • Patent number: 5011593
    Abstract: A hydrodesulfurization process for catalytically hydrosulfurizing highly aromatic feeds, especially catalytically cracked feeds such as light cycle oils from catalytic cracking processes and aromatic extracts, employs a hydrodesulfurization catalyst containing zeolite beta. The zeolite beta based catalyst is more effective for effecting desulfurization than comparable amorphous catalysts or catalysts based on other large pore size zeolite and is capable of achieving a high degree of desulfurization at relatively low levels of conversion. The hydrodesulfurization catalyst comprises a transition metal hydrogenation component, preferably Co/Mo, on zeolite beta together with an inert matrix. The zeolite beta based catalyst may be mixed with amorphous catalyst such as Co/Mo/alumina. The low sulfur products are useful as blending components for road diesel fuels and other distillate fuels.

  • Patent number: 4990713
    Abstract: High viscosity index, low pour point lubricants are produced by reacting an iso-paraffinic component, preferably with significant mono- and di-methyl chain branching, with an olefinic reactant in the presence of a free radical generator such as an organic peroxide, preferably ditertiary butyl peroxide. The isoparaffinic reactant is preferably obtained by the isomerization of a waxy feed such as slack wax over a zeolite beta isomerization catalyst, preferably Pt/zeolite beta. The olefinic reactant is preferably a distillate fraction produced by the oligomerization of low molecular weight olefins e.g., C.sub.3 to C.sub.5 olefins, produced by oligomerization over an intermediate pore size zeolite oligomerization catalyst such as ZSM-5.

  • Patent number: 4983273
    Abstract: A hydrocracking process employing a hydrocracking catalyst based on zeolite beta together with a metal hydrogenation/dehydrogenation component recycles the unconverted, hydrocracked bottoms fraction to the hydrocracking step for improvements in distillate selectivity and denitrogenation without loss of catalyst activity while improving dewaxing of the unconverted bottoms fraction. The process typically operates at low to moderate hydrogen pressures up to 1500 psig (10445 kPa) with low hydrogen consumptions typically below 800 SCF/Bbl (142 n.l.l..sup.-1). Denitrogenation is notably high at 90 weight percent or higher.

  • Patent number: 4913794
    Abstract: A process is disclosed for improving the Viscosity Index of a hydrocarbon lubricating oil comprising the steps of providing a flow reactor having separate first and second inlet ports for the separate co-injection of lubricating oil and an organic peroxide, charging said lubricating oil and said organic peroxide of said flow reactor through said first and second inlet ports respectively, controlling the relative flowrates of said lubricating oil and organic peroxide reactants together with the total volumetric flowrate through said flow reactor to maintain a flow regime which favors diffusional mixing between said organic peroxide and said lubricating oil, and maintaining said organic peroxide and said lubricating oil under conversion conditions including temperatures of between about 50.degree. and 300.degree. C. and pressure sufficient to maintain said lubricating oil and said organic peroxide substantially in the liquid phase.

  • Patent number: 4911823
    Abstract: Heavy hydrocarbon oils of high paraffin content are catalytically cracked using zeolite beta. The paraffin content of the oil is at least 20 weight percent or higher. The gasoline cracking products have a high octane rating and the higher boiling products a decreased pour point resulting from the dewaxing activity of the zeolite beta. The use of cracking temperatures above 500.degree. C., preferably above 550.degree. C., also improves iso-butene production.

  • Patent number: 4740292
    Abstract: Heavy oils are simultaneously subjected to cracking and dewaxing in the absence of added hydrogen using a catalyst comprising Zeolite Beta and an X or Y or other faujasite zeolite. The process is able to effect a bulk conversion of the oil, while, at the same time, yielding a higher octane gasoline, increased yields of C.sub.3 and C.sub.4 olefins, and a low pour point distillate product.

  • Patent number: 4647368
    Abstract: An upgrading process for paraffinic naphthas subjects a full range naphtha to hydrocracking over a zeolite beta hydrocracking catalyst to effect a selective, partial hydrocracking in which the higher molecular weight n-paraffinic components of the naphtha are hydrocracked preferentially to the lower molecular weight components with concurrent isomerization of n-paraffins to isoparaffins, to form a hydrocracked effluent which comprises isobutane, C.sub.5 to C.sub.7 paraffins and relatively higher boiling naphthenes and paraffins. The hydrocracked effluent is split to remove the isobutane and the C.sub.5 and C.sub.7 paraffins with the balance of the higher boiling components being used as a reformer feed. Removal of the C.sub.5 and C.sub.7 paraffins permits improved reformer operation with the production of a higher octane product. The isomerization of the paraffins which occurs in the hydrocracking step provides a C.sub.5 to C.sub.
