Abstract: Systems and methods are provided for integration of an oxygenate conversion process with an olefin oligomerization process. The integrated process can produce gasoline of a desired octane and/or distillate fuel of a desired cetane.

Abstract: Systems and methods are provided for reducing the end point of distillate fuel boiling range fractions while reducing or minimizing conversion of the distillate fuel to naphtha or light ends. To perform end point reduction, a distillate boiling range fraction is exposed to a conversion catalyst that has a total surface area of at least 200 m2/g, an average pore size of 12 Angstroms or more, and/or a low acidity, where the conversion catalyst includes a supported Group 8-10 metal, such as a supported Group 8-10 noble metal. Such a conversion catalyst can have improved activity for reducing end point of a distillate fuel fraction while reducing or minimizing conversion relative to 177° C. Performing end point reduction using such a catalyst can allow for increased yields of distillate fuel boiling range products by allowing increased amounts of heavy feed components to be included in the input to a distillate fuel processing train.

Abstract: Systems and methods are provided for inclusion of olefins in the reaction environment for an oxygenate conversion process. For conversion processes involving a metal-promoted zeolitic catalyst, addition of olefins to an oxygenate feed can reduce or minimize loss of aromatic selectivity as the catalyst is exposed to the feed. Additionally or alternately, for conversion processes involving a zeolitic catalyst including a zeolite other than an MFI framework type zeolite, addition of olefins to an oxygenate feed can reduce or minimize loss of activity for oxygenate conversion as the catalyst is exposed to the feed.
