    摘要： In a process for producing xylene by transalkylation of a C9+ aromatic hydrocarbon feedstock with a C6 and/or C7 aromatic hydrocarbon, the C9+ aromatic hydrocarbon feedstock, at least one C6 and/or C7 aromatic hydrocarbon and hydrogen are contacted with a first catalyst comprising (i) a first molecular sieve having a Constraint Index in the range of about 3 to about 12 and (ii) at least first and second different metals or compounds thereof of Groups 6 to 12 of the Periodic Table of the Elements. Contacting with the first catalyst is conducted under conditions effective to dealkylate aromatic hydrocarbons in the feedstock containing C2+ alkyl groups and to saturate C2+ olefins formed so as to produce a first effluent. At least a portion of the first effluent is then contacted with a second catalyst comprising a second molecular sieve having a Constraint Index less than 3 under conditions effective to transalkylate C9+ aromatic hydrocarbons with said at least one C6-C7 aromatic hydrocarbon to form a second effluent comprising xylene.

    摘要： This invention provides processes for transporting catalyst, preferably in an oxygenate to olefins reaction system. In one embodiment, an oxygenate contacts molecular sieve catalyst particles in a reactor under conditions effective to form an effluent stream comprising light olefins and forming coked catalyst particles. At least a portion of the coked catalyst particles are transported from the reactor or a device associated therewith to a catalyst regenerator through a conduit in a fluidized manner with a fluidizing medium comprising air and steam. At least a portion of the coked catalyst particles are regenerated in the catalyst regenerator to form regenerated catalyst particles, which are ultimately directed back to the reactor.

    摘要： A process is disclosed for alkylating an isoparaffin with an olefin comprising the steps of:(a) reacting an isoparaffin having from 4 to 8 carbon atoms with an olefin having from 2 to 12 carbon atoms in a first alkylation reaction stage at temperature from about -40.degree. C. to about 500.degree. C. and overall isoparaffin:olefin feed weight ratio of from about 1:1 to about 250:1 with a solid alkylation catalyst comprising a synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table I of the specification and having a composition comprising the molar relationshipX.sub.2 O.sub.3 :(n)YO.sub.2,wherein n is less than about 35, X is a trivalent element and Y is a tetravalent element;(b) mixing the effluent from said first alkylation stage with additional olefin to evolve an intermediate stream having an isoparaffin:olefin weight ratio of from about 2:1 to about 100:1; and(c) reacting said intermediate stream in a second alkylation stage in the absence of intermediate fractionation with a liquid acid catalyst comprising H.sub.2 SO.sub.4 to produce C.sub.5 + alkylate.
