The invention relates generally to a sodium faujasite catalyst, and in particular the use of the sodium faujasite catalyst in producing acrylic acid. In particular, the invention relates to the use of the sodium faujasite catalyst in catalytic dehydration of lactic acid and 3-hydroxypropionic acid (3-HP) to produce acrylic acid.

Method for preparing a sodium faujasite catalyst and its use in producing acrylic acid

The invention relates to a catalyst, comprising a catalytic element disposed on a substrate, wherein said substrate has formula CeMO, wherein x is between about 0 and about 0.3, optionally between about 0.01 and about 0.3, and wherein M, if present, is a metallic element other than Ce, when used for catalysing a methanation reaction. There is also described use of the catalyst for catalysing a methanation reaction and a method for methanation of a feedstock including carbon monoxide and hydrogen, said method comprising contacting the feedstock with the catalyst.

Methanation catalyst

The invention relates to use of a catalyst comprising particles of nickel dispersed in a porous silica matrix for catalyzing a methanation reaction. There is also described a method for methanation of a feedstock at least comprising gases carbon monoxide and hydrogen, said method comprising contacting the feedstock with the catalyst.

The present invention provides the use of a metal-doped hydroxyapatite catalyst for highly selective conversion of an alcohol to an aldehyde at low temperatures. More specifically, the invention provides the use of a silver-doped hydroxyapatite catalyst for the highly selective oxidative dehydrogenation of ethanol to acetaldehyde. The present invention also provides the method for converting ethanol to acetaldehyde using a silver-doped hydroxyapatite catalyst.

Metal-doped hydroxyapatite catalyst

A heated reaction gas comprising methane is contacted with first and second catalysts to catalyze production of an aromatic hydrocarbon. The first catalyst is more active than the second catalyst for catalyzing aromatization of methane, and the second catalyst is more active than the first catalyst for catalyzing aromatization of ethane. A reactor for producing aromatic hydrocarbons from the reaction gas may have a conduit defining a reaction zone for the reaction gas to react therein, and the first and second catalysts may be disposed in the reaction zone.

Aromatization of methane with combination of catalysts

Provided are processes for removing sulfur-containing compounds from fuel, comprising contacting the fuel in liquid phase with air to oxidize the sulfur-containing compounds, the contacting being carried out in the presence of at least one transition metal oxide catalyst, wherein the catalyst is supported on a porous support and wherein the porous support comprises a support material selected from the group consisting of a titanium oxide, a manganese oxide and a nanostructured material of the aforementioned support materials.
