Abstract: A hydrocarbon conversion process is described. The process includes contacting in a reactor an inert gas with one or more catalyst compositions suitable for methylation of toluene and hydrogenation of phenol; contacting a reducing agent with the one or more catalyst compositions under conditions suitable for reducing metal oxide content of the catalyst composition; contacting at least part of toluene and/or benzene-containing with a oxygenate in the presence of the one or more catalyst compositions and under conditions effective to convert toluene to xylenes and produce a reactor effluent stream comprising para-xylene and having a lower concentration of phenol than the toluene-containing stream; separating at least one para-xylene-enriched stream from the reactor effluent stream; and separating from the at least one para-xylene enriched stream at least one toluene-enriched stream and at least one para-xylene-product stream. An apparatus for carrying out such a process is also described.

Abstract: In a process for producing biphenyl compounds, a Cn aromatic hydrocarbon may be hydroalkylated to give C2n cycloalkylaromatic compounds and byproduct Cn saturated cyclic hydrocarbons. The C2n cycloalkylaromatic compounds are dehydrogenated to provide the biphenyl compounds. The Cn saturated cyclic hydrocarbons may also be dehydrogenated back to the corresponding Cn aromatic hydrocarbon, which may be recycled to provide additional feed. Although both the intermediate C2n cycloalkylaromatic compounds and the byproduct Cn saturated cyclic hydrocarbons should be dehydrogenated, at least part of the dehydrogenation of the Cn saturated cyclic hydrocarbons should take place in the absence of C2n or greater hydrocarbons. Thus, dehydrogenation of the byproduct Cn saturated cyclic hydrocarbons should take place at least in part separately from dehydrogenation of the C2n cycloalkylaromatic compounds.

Abstract: In a process for producing 3,4′ and/or 4,4′ dimethyl-substituted biphenyl compounds, a feed comprising toluene is contacted with hydrogen in the presence of a hydroalkylation catalyst under conditions effective to produce a hydroalkylation reaction product comprising (methylcyclohexyl)toluenes. At least part of the hydroalkylation reaction product is dehydrogenated in the presence of a dehydrogenation catalyst under conditions effective to produce a dehydrogenation reaction product comprising a mixture of dimethyl-substituted biphenyl isomers.
