Abstract: Systems and methods are provided for conversion of oxygenate feeds to lubricant and/or distillate boiling range compounds with desirable properties by first selectively converting oxygenates to light olefins and then converting the light olefins to distillate and lubricant boiling range compounds with beneficial properties. The distillate boiling range products can have an unexpectedly high cetane, while the lubricant boiling range products can have an unexpectedly high viscosity index. The ability to form the distillate boiling range products and lubricant boiling range products is facilitated by using a Ni-enhanced oligomerization catalyst.

Abstract: Systems and methods are provided for modifying the composition of the conversion catalyst in a reactor for oxygenate conversion during conversion of an oxygenate feed to allow for adjustment of the slate of conversion products. The modification of the conversion catalyst can be performed by introducing a substantial portion (relative to the amount of catalyst inventory in the reaction system) of make-up catalyst having a distinct composition relative to the conversion catalyst in the reaction system. Introducing the distinct composition of make-up catalyst can modify the composition of the conversion catalyst in the reactor to allow for changes in the resulting product slate. By introducing the distinct catalyst composition, the conversion catalyst in the reactor can correspond to a different composition of catalyst than the overall average catalyst composition within the catalyst inventory in the reaction system.
