    摘要： In one embodiment, a reactor includes a reactor body and a reactor head. The reactor head has a reactor head body and one or more inlets disposed tangentially to the reactor head body. In one embodiment, a polymerization process for forming polymer includes introducing in a first direction a stream including a monomer. The stream and a catalyst system are flowed in a second direction through at least one internal heat exchanger. The second direction is substantially orthogonal to the first direction. The reaction zone includes at least one internal heat exchanger. At least a portion of the monomer of the stream is polymerized in the reaction zone to produce a polymer product. The polymer product is recovered from the reaction zone.

    摘要： A process and related system for producing para-xylene (PX). In an embodiment, the process includes (a) separating a feed stream comprising C6+ aromatic hydrocarbons into a toluene containing stream and a C8+ hydrocarbon containing stream and (b) contacting at least part of the toluene containing stream with a methylating agent in a methylation unit to convert toluene to xylenes and produce a methylated effluent stream. In addition, the process includes (c) recovering PX from the methylated effluent stream in (b) to produce a PX depleted stream and (d) transalkylating the PX depleted stream to produce a transalkylation effluent stream. The transalkylation effluent stream includes a higher concentration of toluene than the PX depleted stream. Further, the process includes (e) converting at least some ethylbenzene (EB) within the C8+ hydrocarbon containing stream into toluene and (f) flowing the toluene converted in (e) to the contacting in (b).

    摘要： In a process for producing phenol, a cleavage feed comprising cyclohexylbenzene hydroperoxide is supplied to a cleavage reaction zone and a cleavage reaction mixture comprising the cleavage feed is contacted in the cleavage reaction zone with a solid acid catalyst under conditions effective to produce a cleavage effluent comprising phenol and cyclohexanone. The cleavage effluent is then divided into at least a cleavage product and a cleavage recycle and the cleavage recycle and a polar solvent is supplied to the cleavage reaction zone to produce the cleavage reaction mixture with the cleavage feed. Preferably, the polar solvent is combined with the cleavage recycle before being charged into the cleavage reaction zone.

    摘要： In a process for producing cyclohexylbenzene, hydrogen and benzene are introduced to a first hydroalkylation reaction zone which contains a hydroalkylation catalyst and which is operated under at least partly liquid phase conditions sufficient to effect hydroalkylation of benzene to produce a mixed liquid/vapor phase effluent comprising cyclohexylbenzene and unreacted benzene, wherein at least a portion of the unreacted benzene is in the vapor phase. At least a portion of the effluent is cooled to condense a liquid phase stream containing at least some of the cyclohexylbenzene in the effluent portion and leave a residual stream containing at least some of the unreacted benzene and cyclohexylbenzene. At least a portion of the liquid stream is recycled to the first hydroalkylation reaction zone or to contact the mixed phase effluent exiting the first hydroalkylation reaction zone. Other methods of cooling the reaction effluent are disclosed.
