    摘要: In a process for producing cyclohexylbenzene, benzene is reacted with cyclohexene in a first reaction zone under conditions effective to produce a reaction product comprising cyclohexylbenzene and at least one polycyclohexylbenzene. At least a portion of the reaction product and a stripping agent comprising at least one C1 to C11 hydrocarbon or hydrogen are then separately supplied to a separation device and separated into at least a first fraction rich in cyclohexylbenzene and a second fraction rich in the at least one polycyclohexylbenzene.

    摘要: In a process for alkylation of an alkylatable aromatic compound to produce a monoalkylated aromatic compound, a first feed stream comprising fresh alkylatable aromatic compound is passed to a first reaction zone which comprises a transalkylation catalyst and which also receives a second feed stream comprising polyalkylated aromatic compounds. The first and second feed streams are contacted with the transalkylation catalyst in the first reaction zone under conditions to transalkylate the polyalkylated aromatic compounds with the alkylatable aromatic compound to produce the desired monoalkylated aromatic compound. A first effluent stream comprising unreacted alkylatable aromatic compound and the monoalkylated aromatic compound is removed from the first reaction zone and passed to a fractionation system to separate the first effluent stream into a first light fraction comprising the unreacted alkylatable aromatic compound and a first heavy fraction comprising the monoalkylated aromatic compound. At least part of one or more impurities in the fresh feed stream are removed in the first reaction zone.

    摘要: This invention provides for a process for hydrocarbon conversion in which a partially dehydrated hydrocarbon feedstock is contacted with at least two different molecular sieve materials, including a first molecular sieve having a Si/Al molar ratio of less than about 5 and a second molecular sieve having a Si/Al molar ratio of greater than about 5. Also, this invention includes such processes in which such feedstocks are contacted with a first molecular sieve having pores of at least about 6 Angstroms and a second molecular sieve having pores of less than about 6 Angstroms.
