This present disclosure relates to processes and apparatuses for toluene methylation in an aromatics complex for producing paraxylene. More specifically, the present disclosure relates to processes and apparatuses wherein a toluene methylation zone is integrated within an aromatics complex for producing paraxylene thus allowing no benzene byproduct to be produced. This may be accomplished by incorporating a toluene methylation process into the aromatics complex and recycling the benzene to the transalkylation unit the aromatics complex.

Processes for catalytically converting oxygenates to hydrocarbon products having an increased C.sub.6-C.sub.8 aromatics content therein. A first mixture comprising 10.0 wt. % of at least one oxygenate, based on the weight of the first mixture, contacts a catalyst in a fluidized bed reactor to produce a product stream including water, one or more hydrocarbons comprising 30.0 wt. % of aromatics, based on the weight of the hydrocarbons in the product stream, hydrogen, and one or more oxygenates. The catalyst comprises at least one molecular sieve, a binder, and at least one element selected from Groups 2-14 of the Periodic Table. At least one water-rich stream, at least one aromatic-rich hydrocarbon stream, and at least one aromatic-depleted hydrocarbon stream are separated from the product stream, and at least a portion of one of the aromatic-rich hydrocarbon stream or the aromatic-depleted hydrocarbon stream is recycled back to the reactor.

Methods are provided for refining natural oil feedstocks. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the olefins from the esters in the metathesized product. In certain embodiments, the methods further comprise hydrogenating the olefins under conditions sufficient to form a fuel composition. In certain embodiments, the methods further comprise transesterifying the esters in the presence of an alcohol to form a transesterified product.
