A catalyst may include a support and from 5 to 20 wt.-% of a promoter, based on the total weight of the catalyst, wherein the support may include titanium dioxide, zirconium dioxide, and/or a mixture thereof, and the promoter may be an alkali metal oxide. Processes for preparing such catalysts may include impregnating a support of titanium dioxide and/or zirconium dioxide with an aqueous solution including a preferably soluble alkali compound and calcining. Alkyl mercaptans may be prepared in the presence of such catalysts or catalysts obtained by such processes.

The invention provides methods, catalysts and systems for producing styrene from DME and toluene. Zeolite catalysts comprising potassium, rubidium or cesium and containing at least 0.1 wt % B are described. Methods of making the catalysts are also described.

A process for producing a catalyst including a) providing an uncalcined metal modified porous silica support wherein the modifier metal is selected from one or more of boron, magnesium, aluminium, zirconium, hafnium and titanium, wherein the modifier metal is present in mono- or dinuclear modifier metal moieties; b) optionally removing any solvent or liquid carrier from the modified silica support; c) optionally drying the modified silica support; d) treating the uncalcined metal modified silica support with a catalytic metal to effect adsorption of the catalytic metal onto the metal modified silica support; and e) calcining the impregnated silica support of step d). The invention extends to an uncalcined catalyst intermediate and a method of producing a catalyst by providing a porous silica support having isolated silanol groups.

A method of forming a catalyst is provided herein. The method comprises combining a binder, a support, and an active metal to form a slurry composition. The method further comprises applying the slurry composition using an additive manufacturing process to form a green part. The method further comprises exposing the green part to heat at a temperature of from about 10° C. to about 150° C. to form the hardened part. The method further comprises applying a ceramic-based coating material to the hardened part to form the catalyst.

Methods for engineered cellular magmatic usable as filter media and articles thereof are disclosed. For example, the magmatics may include one or more infiltration materials that are configured not to sinter when a foamed mass is formed. The infiltration materials may be enclosed in cells of the foamed mass and may be floating and/or fixed to the cell walls.
