A catalyst includes a mixed metal oxide; an alumina; silica, and calcium, where the mixed metal oxide includes Cu and at least one of Mn, Zn, Ni, or Co. Such catalysts exhibit enhanced tolerance sulfur-containing compounds and free fatty acids.

Hydrogenolysis catalysts with high acid tolerance

A process of forming an ethynylation catalyst includes providing a slurry including water, a copper-containing material, a bismuth-containing material, a structural material, and a binder; spray-drying the slurry to form particles; and calcining the particles to form the ethynylation catalyst.

Spray-dried butynediol catalysts

Catalysts and methods for their manufacture and use for the dehydrogenation of alcohols are disclosed. The catalysts and methods utilize a highly dispersible alumina, for example, boehmite or pseudoboehmite, to form catalysts that exhibit high dehydrogenation activities. Specifically, the catalysts include Cu that is highly dispersed by reaction of an alumina formed by peptizing of boehmite or pseudoboehmite and precursors of ZrO, ZnO and CuO.

Copper-zirconia catalyst and method of use and manufacture

Provided are catalysts suitable for the production of tetrahydrofuran from 1,4-butanediol. Also provided are methods of use of these catalyst, as well as catalyst systems. The catalysts described herein contain only Lewis acidity, but not Br&#xf8;nsted acidity, which results in decreased production of ether byproducts.

Catalyst for tetrahydrofuran synthesis

Provided are catalysts suitable for the production of tetrahydrofuran from 1,4-butanediol. Also provided are methods of use of these catalyst, as well as catalyst systems. The catalysts described herein contain only Lewis acidity, but not Bro&#xf8;nsted acidity, which results in decreased production of ether byproducts.

A novel catalyst useful in the ethynylation of formaldehyde to butynediol is formed by precipitating copper and bismuth from a salt solution of such metals, utilizing an alkali metal hydroxide as the precipitating agent to deposit copper and bismuth hydroxide as a coating around a siliceous carrier particle.

Ethynylation catalyst and method of making same

Provided are hydrogenation catalysts for processing esters into fatty alcohols. More particularly, the catalysts are for vapor-phase hydrogenation of methyl esters to fatty alcohols under fixed-bed conditions, where conditions are typically in a temperature range of 200 to 250&#xb0; C. and a pressure range of 30 to 50 bar. Methods of making and using the same are also provided. These catalysts comprise a copper chromite, an alkali metal or alkaline earth metal component, and an inorganic matrix component, which are processed together to form the catalyst. The alkali metal component can comprise sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), or combinations thereof. The alkaline earth metal can comprise magnesium (Mg), calcium (Ca), barium (Ba), or combinations thereof.

Copper Chromite hydrogenation catalysts for production of fatty alcohols

Disclosed is a catalyst composite containing a metal catalyst and a specifically defined carbon support containing a carbonaceous material. For example, the carbon support may have a total pore surface area of about 800 m/g or more and about 2,000 m/g or less where about 20% or less of the total pore surface area is micro pore surface area. Alternatively the carbon support may have a total pore volume of at least about 0.75 cc/g where about 15% or less of the total pore volume is micro pore volume. Alternatively, the carbon support may have a phosphorus content of about 0.75% by weight or less. Also disclosed are methods of making and using the catalyst composite.

Precious metal catalyst for debenzylation

One aspect of the invention relates to catalyst composite containing a metal catalyst and a specifically defined carbon support containing a carbonaceous material.
