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: 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: Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.

Abstract: A method of producing bifunctional catalyst systems that include a carbon-coated metal catalyst may comprise: coating a metal catalyst particle with a carbon-containing small molecule to produce a coated metal catalyst particle; carbonizing the carbon-containing small molecule on the coated metal catalyst particle to produce a carbon-coated metal catalyst particle; and mixing the carbon-coated metal catalyst particle with an acid catalyst particle to produce an acid/metal bifunctional catalyst system. Further, a method of producing bifunctional catalyst systems that include a carbon-coated acid catalyst may be similarly performed by coating a metal catalyst particle with a carbon-containing small molecule to produce a coated metal catalyst particle; carbonizing the carbon-containing small molecule on the coated metal catalyst particle to produce a carbon-coated metal catalyst particle; and mixing the carbon-coated metal catalyst particle with an acid catalyst particle to produce an acid/metal bifunctional catalyst system.
