Abstract: A method of producing bifunctional catalysts by extrusion may include mixing an acid catalyst, a metal catalyst, optionally a binder, and a fluid to produce a dough; extruding the dough to form an extrudate; producing a powder from the extrudate; and calcining the powder to produce an acid/metal bifunctional catalyst. Such acid/metal bifunctional catalysts may be useful in, among other things, converting syngas to dimethyl ether in a single reactor.

Abstract: The disclosure generally relates to CCS sorbents, particularly for CO2/H2O displacement desorption process. The sorbents include an aluminum oxide support that includes two alkali metal salts impregnated on the support. The two alkali metals include a potassium metal salts and a second alkali metal salt which is not potassium. The second metal salt disrupts poisoning effects that degrade sorbent lifetime. The sorbents demonstrate improved CO2 loadings and better H2O/CO2 ratios, as well as improved stability. Compositions and methods of making are disclosed.

Abstract: A process for separating a carbon dioxide from a gas stream is disclosed. The process can include passing the gas stream over a sorbent that adsorbs the carbon dioxide by concentration swing adsorption and adsorptive displacement. The sorbent can be regenerated and the carbon dioxide recaptured by desorbing the carbon dioxide from the sorbent using concentration swing adsorption and desorptive displacement. A carbon dioxide separation system is also disclosed. Neither the system nor the process rely on temperature swing or pressure swing adsorption.

Abstract: Described herein are novel and inventive dewaxing processes that employ dewaxing catalysts which are co-extrusions of two different zeolites, particularly two different 10MR zeolites or a co-extrusion of a 10MR zeolite and a 12MR zeolite in combination with a hydrogenation component. The hydrogenation component can be a mixture of non-noble metal components or a mixture of noble metal components. This novel and inventive process demonstrated a significant activity boost (as measured by increased cloud point reduction) and/or selectivity boost (as measured by reduced diesel loss) compared to either single zeolite component.

Abstract: Methods of producing metal catalysts can include mixing two or more metal salts and an aluminum salt in water to produce a metal catalyst precursor solution; mixing the metal catalyst precursor solution and an alkali metal buffer solution to produce a precipitate; ion exchanging the alkali metal in the precipitate for a non-alkali cation to produce a low-alkali metal precipitate comprising 3 wt % or less alkali metal by weight of the precipitate on a dry basis; producing a powder from the low-alkali metal precipitate; and calcining the powder to produce a metal catalyst. Such metal catalysts may be useful in producing bifunctional catalyst systems that are useful in, among other things, converting syngas to dimethyl ether in a single reactor

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 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. This can provide sufficient dewaxing activity to achieve a desired level of improvement in cold flow properties at the lower hydrotreating temperatures that are generally desired near the start of operation of a hydrotreating reactor. In other aspects, the methods can include use of MEL dewaxing catalysts with reduced ratios of molecular sieve to binder so that trim dewaxing can be provided while maintaining a desirable yield under end-of-run hydrotreating conditions.
