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.

Abstract: Methods and catalysts are provided for performing dewaxing of diesel boiling range fractions, such as trim dewaxing, that allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. In some aspects, the methods can include use of dewaxing catalysts based on an MEL framework structure (ZSM-11) to provide improved dewaxing activity. In some aspects improved dewaxing is achieved operating at lower pressures and with higher amounts of organic nitrogen slip from hydrotreatment.

Abstract: Methods are provided for liquid phase activation of dewaxing and/or hydrofinishing catalysts that include a molecular sieve or other acidic crystalline support. The methods are compatible with activating the catalysts as part of a catalyst system that also includes a hydrotreating catalyst.

Abstract: Methods are provided for making base metal catalysts with improved activity. After forming catalyst particles based on a support comprising a zeolitic molecular sieve, the catalyst particles can be impregnated with a solution comprising a) metal salts (or other precursors) for a plurality of base metals and b) an organic dispersion agent comprising 2 to 10 carbons. The impregnated support particles can be dried to form a base metal catalyst, and then optionally sulfided to form a sulfided base metal catalyst. The resulting (sulfided) base metal catalyst can have improved activity for cloud point reduction and/or for improved activity for heteroatom removal, relative to a base metal dewaxing catalyst prepared without the use of a dispersion agent.

Abstract: Systems and methods are provided for activation of noble metal catalysts that are supported on siliceous supports. The activation method can include limiting the amount of water vapor pressure and/or the time of exposure to the water vapor pressure during heating of the catalyst at temperatures of 50° C. or less. This can be achieved by introducing heated gas into multiple reactors of a multi-reactor system at the same time. A suitable system for introducing heated gas into multiple reactors can correspond to a system with multiple heated hydrogen lines for delivery of heated hydrogen to a plurality of reactors within a multi-reactor system.

Abstract: Methods are provided for dewaxing distillate feeds using a dewaxing catalyst with improved aromatic saturation activity. The dewaxing can be performed using a catalyst including a zeolitic molecular sieve with a beneficial ratio of zeolitic molecular sieve to binder and/or using a catalyst including a zeolitic molecular sieve with a reduced ratio of silica to alumina.
