Abstract: Methods are provided for improving the yield of aromatics during conversion of oxygenate feeds. An oxygenate feed can contain a mixture of oxygenate compounds, including one or more compounds with a hydrogen index of less than 2, so that an effective hydrogen index of the mixture of oxygenates is between about 1.4 and 1.9. Methods are also provided for converting a mixture of oxygenates with an effective hydrogen index greater than about 1 with a pyrolysis oil co-feed. The difficulties in co-processing a pyrolysis oil can be reduced or minimized by staging the introduction of pyrolysis oil into a reaction system. This can allow varying mixtures of pyrolysis oil and methanol, or another oxygenate feed, to be introduced into a reaction system at various feed entry points.

Abstract: Methods are provided for forming aromatic compounds from a highly unsaturated aliphatic feeds optionally in combination with methanol. The method can include dehydrogenating a feed containing at least about 50 vol % C1-C4 alkanes under dehydrogenation conditions to form a dehydrogenation effluent containing at least about 25 vol % alkynes. Alternatively, other sources of alkyne-containing feeds can be used. At least a portion of the alkyne-containing feed can then be converted under effective conversion conditions to form a conversion effluent comprising a hydrocarbon product containing aromatic compounds.

Particular processes include (a) providing a first mixture comprising ≧10.0 wt. % of at least one oxygenate, based on the weight of the first mixture; (b) contacting the first mixture with a catalyst to convert the first mixture to a product stream including water, one or more hydrocarbons, hydrogen, and one or more oxygenates, wherein the catalyst comprises at least one molecular sieve and at least one element selected from Groups 2-14 of the Periodic Table and the hydrocarbons comprise ≧30.0 wt. % of aromatics, based on the weight of the hydrocarbons in the product stream; and (c) separating from the product stream at least one water-rich stream, at least one aromatic-rich hydrocarbon stream, and at least one aromatic-depleted hydrocarbon stream.
