    摘要: A process for producing an cumene product having a purity of at least 99.50 percent based on the weight of cumene present in the product by the propylation of the benzene present in non-extracted hydrocarbon composition feed, e.g., non-extracted reformate. The non-extracted hydrocarbon composition feed is substantially free of both C4− hydrocarbons and the C7+ aromatic hydrocarbons and contains benzene and benzene coboilers. The process is carried out in the liquid phase, in the presence of an acid-active catalyst containing MCM-22 family molecular sieve, and under specified conditions.

    摘要: This invention is to a method of oligomerizing an olefin feed stream. The olefin feed stream contains at least one C2 to C12 olefin to obtain an olefin feed stream and has from about 1,000 ppm to about 10 percent by weight oxygenated hydrocarbon. The olefin is oligomerized by contacting with an acid based oligomerization catalyst.

    摘要: This disclosure relates to a process of manufacturing para-xylene, comprising (a) contacting a pygas feedstock and methylating agent with a catalyst under reaction conditions to produce a product having para-xylene, wherein the product has higher para-xylene content than the para-xylene content of the pygas feedstock; and (b) separating the para-xylene from the product of the step (a), wherein the catalyst comprises a molecular sieve having a Diffusion Parameter for 2,2-dimethylbutane of about 0.1-15 sec−1 when measured at a temperature of 120° C. and a 2,2-dimethylbutane pressure of 8 kPa-a and the pygas comprises from about 1 to about 65 wt % benzene and from about 5 to 35 wt % toluene.
