Abstract: Methods, catalysts, and corresponding catalyst precursors are provided for performing dewaxing of diesel or distillate boiling range fractions. The dewaxing methods, catalysts, and/or catalyst precursors can allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. The catalysts and/or catalyst precursors can correspond to supported base metal catalysts and/or catalyst precursors that include at least two Group 8-10 base metals supported on the catalyst, such as a catalyst/catalyst precursor including both Ni and Co as supported metals along with a Group 6 metal (i.e., Mo and/or W). The support can correspond to a support including a zeolitic framework structure. The catalyst precursors can be formed, for example, by impregnating a support including a zeolitic framework structure with an impregnation solution that also includes a dispersion agent.

Abstract: Methods, catalysts, and corresponding catalyst precursors are provided for performing dewaxing of diesel or distillate boiling range fractions. The dewaxing methods, catalysts, and/or catalyst precursors can allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. The catalysts and/or catalyst precursors can correspond to supported metal catalysts and/or catalyst precursors that include at least one noble metal, such as Pt, at least one Group 8-10 base metal, preferably a non-noble Group 8-10 base metal, such as Ni and/or Co along with a Group 6 metal, such as Mo and/or W as supported metals along. The support can include a zeolitic framework structure. The catalyst precursors can be formed, for example, by impregnating a support including a zeolitic framework structure with impregnation solution(s) that also includes a dispersion agent.

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 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.

Abstract: Provided herein are dual riser fluid catalytic cracking processes for producing light olefins from an oxygenate feed, such as a methanol feed, in a conventional FCC unit. In certain aspects the processes comprise cracking a hydrocarbon feed in a first riser comprising a first catalyst under first riser conditions to form a first effluent enriched in olefins, light gasoil, gasoline, or a combination thereof; cracking a hydrocarbon oxygenate feed in a second riser comprising a second catalyst under second riser conditions to form a second effluent enriched in olefins; recovering the first and second catalyst from the first and second effluents in a common reactor; regenerating the recovered first and second catalyst in a regenerator using heat from the exothermic cracking of the hydrocarbon oxygenate feed; and recirculating the regenerated first and second catalyst to the first and second riser.
