    摘要: In a process for producing a hydrocarbon composition, a feed comprising at least one C3 to C8 olefin and an olefinic recycle stream rich in C9− hydrocarbons is contacted with a crystalline molecular sieve catalyst having an average crystal size no greater than 0.05 micron and an alpha value between about 100 and about 600 in at least one reaction zone under olefin oligomerization conditions including an inlet temperature between about 150° C. and about 350° C., a pressure of at least 2,860 kPa and a recycle to feed weight ratio of about 0.1 to about 3.0. The contacting produces an oligomerization effluent stream, which is separated into at least a hydrocarbon product stream rich in C9+ hydrocarbons and the olefinic recycle stream.

    摘要: A process for producing phenol and methyl ethyl ketone comprises contacting benzene and a C4 alkylating agent under alkylation conditions and in the presence of an alkylation catalyst comprising at least one molecular sieve of the MCM-22 family to produce an alkylation effluent comprising secbutylbenzene; wherein the contacting is conducted in a plurality of reaction zones and the C4 alkylating agent secbutylbenzene fraction is recovered from the alkylation effluent and comprises at least 95 wt % sec-butylbenzene, less than 100 wt ppm of C8+ olefins, and less than 0.5 wt % of isobutylbenzene and tert-butylbenzene. The sec-butylbenzene fraction is then oxidized to produce sec-butylbenzene hydroperoxide and the hydroperoxide is cleaved to produce phenol and methyl ethyl ketene.

    摘要: In a process for preparing an alkylaromatic hydrocarbon composition an olefinic hydrocarbon mixture and an aromatic compound are contacted under alkylation conditions with an aromatic alkylation catalyst selected from a homogeneous acid catalyst and heterogeneous acid catalyst comprising a molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstroms. The olefinic hydrocarbon mixture comprises at least 5 wt % by weight of mono-olefin oligomers of the empirical formula: CnH2n wherein n is greater than or equal to 10, the mono-olefin oligomers comprising at least 20 percent by weight of olefins having at least 12 carbon atoms, and the olefins having at least 12 carbon atoms having an average of from 0.8 to 2.0 C1-C3 alkyl branches per carbon chain. Sulfonation of the alkylaromatic hydrocarbon product produces an alkylaryl sulfonate mixture that exhibits advantageous properties, such as biodegradability and hard and cold water performance.

    摘要: This invention provides a method of producing an aromatics alkylation catalyst comprising the steps of:(a) synthesizing a layered oxide material MCM-56 in the presence of alkali and/or alkaline earth metal cations;(b) prior to any calcination of the MCM-56, subjecting the MCM-56 produced in step (a) to ammonium ion exchange so as to at least partially replace the alkaline or alkaline earth metal cations associated with the MCM-56 with ammonium ions; then(c) heating the ammonium-exchanged MCM-56 to decompose the ammonium cations and convert the MCM-56 into the hydrogen form; and(d) after step (b), forming the MCM-56 into catalyst particles.The resultant catalyst exhibits enhanced activity in the alkylation of benzene with ethylene and propylene.
