    摘要： The transfer of hydrogen from a paraffin to an olefin is carried out in the presence of, as catalyst, MCM-36. Especially when the paraffin reactant is an isoparaffin, the olefin produced from the reacted isoparaffin may react with unreacted isoparaffin to also produce an alkylate product.

    摘要： A process for upgrading low octane naphthas to produce gasoline products with low levels of benzene and aromatics while retaining a high pool octane uses a paraffinic naphtha reformer feed which is dehexanized to provide a C.sub.7 + fraction which is fed to the reformer and a C.sub.6 fraction which is fed together with the C.sub.6 fraction from the reformer effluent to a catalytic upgrading step where the low octane components from the naphtha and the benzene from the reformate are converted to a low benzene, high octane gasoline by alkylation of the benzene and other aromatics present in the reformate. The process has the advantage that benzene make in the reformer is reduced by the partial by-passing of the C.sub.6 benzene precursors around the reformer; in addition, improved benzene alkylation results from the presence of additional light olefins generated by the cracking of paraffins from the paraffinic naphtha. the reaction is preferably carried out in a turbulent fluidized bed reaction zone.

    摘要： A process for demetallizing metals contaminated FCC catalyst in an FCC regenerator. A metals getter additive, with higher settling velocity, is added to the regenerator, to remove metals from FCC catalyst by solid-solid interaction. The FCC catalyst forms a light, discrete, dense phase fluidized bed on top of a fluidized bed of additive. FCC catalyst is recycled to the cracking reactor from the top fluidized bed, while additive can be withdrawn from the lower fluidized bed for disposal or for metals recovery and recycle. Additive can be optimized for metals removal and will not dilute the cracking catalyst in the FCC reactor.

    摘要： Olefins are converted to lower alkene hydrocarbon products, e.g., propene, butenes, and isoalkenes with zeolite MCM-22 catalyst. This catalytic conversion is particularly useful in the selective separation of linear olefins in mixed hydrocarbon streams, employing MCM-22 catalyst to convert these straight-chain unsaturated components to lighter products, particularly, C.sub.3 -C.sub.4 olefins. One potential application of this selective separation is in the removal of linear olefins from FCC gasoline.

    摘要： A selective alkene upgrading process wherein a mixture of intermediate molecular weight monoalkenes comprising at least one linear alkene component and at least one tertiary alkene component is contacted under selective olefin interconversion conditions with medium pore, shape selective acid catalyst, such as MCM-22 aluminosilicate zeolite, thereby converting at a major amount of linear intermediate alkene to lower alkene while leaving tertiary alkene substantially unconverted. In the preferred embodiments, the process interconversion conditions comprise reaction temperature in the range of about 300.degree. C. to 550.degree. C., pressure in the range of 100 kpa to 1000 kPa, thereby selectively converting at least 60% (net) of linear intermediate alkene while converting less than 20% (net) of branched alkene. By etherifying at least a portion of the unconverted tertiary alkene, an oxygenated fuel having enhanced octane rating is obtained. Cracked lower olefins may be recovered for upgrading.
