    Abstract: In a process for producing phenol, benzene is hydroalkylated with hydrogen in the presence of a catalyst under conditions effective to produce a hydroalkylation reaction product comprising cyclohexylbenzene and cyclohexane. At least a portion of the cyclohexane from said hydroalkylation reaction product is then dehydrogenated to produce a dehydrogenation effluent comprising benzene, toluene and hydrogen. At least a portion of the dehydrogenation effluent is washed with a benzene-containing stream to transfer at least a portion of the toluene from the dehydrogenation effluent to the benzene-containing stream.

    Abstract: A hydrocarbon conversion process comprises pyrolysing at a temperature ≥700° C. a feedstock comprising hydrocarbon to produce a pyrolysis effluent comprising at least one C2 to C4 olefin and C5+ aliphatic and aromatic hydrocarbons. The pyrolysis effluent is contacted with an oleaginous quench stream to reduce the temperature of the pyrolysis effluent to ≤400° C. At least first and second streams are separated from the cooled effluent. The first stream comprises at least one C2 to C4 olefin, and the second stream comprises a quench oil having an average boiling point at atmospheric pressure of at least 120° C. At least a portion of the second stream is catalytically hydroprocessed to produce a hydroprocessed stream, which is combined with at least a portion of any remainder of the second stream to form the quench stream.

    Abstract: A process including contacting one or more monomers, at least one catalyst system, and at least two condensing agents under polymerizable conditions to produce a polyolefin polymer is provided where the vapor pressure of the condensing agents is ±4 bara of the optimum vapor pressure given by the formula: optimum vapor pressure=614−716*D+2.338*P+3.603*ln(MI), where the optimum vapor pressure has units (bara), D is the polyolefin polymer density with units (g/cc), P is the polymerization condition pressure with units (barg), and MI is the polyolefin polymer melt index with units (g/10 min). The invention also relates to a process where at least three condensing agents are used.
