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: Provided herein are catalysts for dewaxing of a feedstock, the catalyst comprising between about 40 wt. % and about 99.9 wt. % zeolite, between about 0 wt. % and about 40 wt. % binder and at least about 0.1 wt. % noble metal, as well as catalyst systems, methods and products produced using the catalysts. The zeolite having a crystal comprising a largest included sphere less than or equal to about 7.5 angstroms, a largest diffusing sphere greater than or equal to about 5.0 angstroms, and a silica to alumina ratio greater than or equal to about 100:1. The catalyst having a temperature-programmed ammonia desorption (“TPAD”) of less than about 0.25 mmol/g.

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 having a pH of about 2.5 to about 4.0; mixing the metal catalyst precursor solution and a basic solution having a pH of about 10 to about 13 to produce a mixture with a pH of about 6 to about 7 and a precipitate; producing a powder from the 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 a acid/metal bifunctional catalyst may include: mixing an acid catalyst, a metal catalyst, and a fluid to produce a slurry, wherein the acid catalyst is present at 50 wt % or less relative to a total catalyst weight in the slurry; heating the slurry; producing a powder from the slurry; and calcining the powder to produce the acid/metal bifunctional catalyst. Such acid/metal bifunctional catalyst would be useful in the direct conversion of syngas to dimethyl ether as well as other reactions.

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.

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.
