Method for the preparation of a monolithic catalyst for the reduction of nitrogen oxides VOC and carbon monoxide in an off-gas, the catalyst comprises at least one platinum group metal, vanadium, titania and optionally tungsten oxide.

Method for preparation of a monolithic catalyst for the reduction of nitrogen oxides, VOC and carbon monoxide in an off-gas

A method in which flue gas or exhaust gas containing harmful carbon monoxide, organic compounds (VOC) and NOx is contacted with a layered catalyst. A first layer of the catalyst comprises an oxidation catalyst. An underlying layer of the catalyst comprises a NH3-SCR catalyst for the simultaneous removal of the carbon monoxide and NOx.

Method for the simultaneous removal of carbon monoxide and nitrogen oxides from flue or exhaust gas

Process for the preparation of hydrogen and carbon monoxide rich gas by steam reforming of hydrocarbon feedstock in presence of a steam reforming catalyst supported as thin film on the wall of a reactor, comprising steps of (a) optionally passing a process gas of hydrocarbon feedstock through a first reactor with a thin film of steam reforming catalyst supported on walls of the reactor in heat conducting relationship with a hot gas stream; (b) passing effluent from the first reactor to a subsequent tubular reactor being provided with a thin film of steam reforming catalyst and/or steam reforming catalyst pellets and being heated by burning of fuel, thereby obtaining a partially steam reformed gas effluent and a hot gas stream of flue gas; (c) passing the effluent from the second reactor to an autothermal reformer; and (d) withdrawing from the autothermal reformer a hot gas stream of product gas rich in hydrogen and carbon monoxide.

Synthesis gas production by steam reforming

Process for the preparation of hydrogen and carbon monoxide rich gas by catalytic steam reforming of a hydrocarbon feedstock comprising steps of: (a) optionally passing a process gas of hydrocarbon feedstock through a first reactor with a steam reforming catalyst heated by a hot gas stream; (b) passing the effluent from the first reactor to a subsequent tubular reactor containing a steam reforming catalyst and being heated by burning of fuel, thereby obtaining a hot gas stream of steam reformed product gas and a hot gas stream of flue gas; and wherein a reforming catalyst is placed on a metallic support having substantially the same shape as a wall of the reactor and being arranged in heat conduction relationship with the reactor wall.

Synthesis gas production by steam reforming using catalyzed hardware

A process for the preparation of hydrogen and carbon monoxide rich gas by steam reforming of a hydrocarbon feedstock in the presence of a steam reforming catalyst disposed in the pores of a porous supporting structure aligned and adhered along the wall of a reforming reactor.

Method of manufacturing catalyzed hardware including adhering a porous structure on the hardware, applying to and/or within the porous structure a ceramic carrier material and applying catalytic active material to the ceramic carrier material.

Catalyzed hardware

The process of this invention prepares a hydrogen and carbon monoxide rich gas stream by passing a hydrocarbon feedstock mixed with steam to a tubular reaction with a thin layer of film of a steam reforming catalyst supported on the inner walls thereof; passing the effluent from the tubular reaction to a fixed bed steam reforming catalyst; and withdrawing from the fixed bed a hydrogen and carbon dioxide rich product gas, said tubular reactors being heated burning of fuel. Optionally, the feed to the tubular reactor herein designated the second tubular reactor, may be the effluent from a similar tubular reactor, herein designated the first tubular reactor in heat conducting relationship with hot flue gas from the second reactor.

A monolithic, structured catalyst for the preparation of aldehydes. Alcohol is converted to a corresponding aldehyde by partial oxidation of the alcohol using the catalyst which includes an active catalytic material and a monolithic, inert carrier for the same. The active material includes oxides of molybdenum and oxides of chromium, vanadium, aluminum, iron, tungsten, manganese and mixtures thereof.

Catalyst for preparing aldehyde

A catalyst for the partial oxidation of an alcohol to a corresponding aldehyde. The catalyst includes a monolithic structured inert carrier and an active catalytic mixture of oxides of molybdenum and either chromium, vanadium, aluminum, iron, tungsten, manganese or mixtures thereof in a molar ratio of the molybdenum oxide to the other oxide or oxides of between 1 and 5. The catalyst has a reduced pressure drop compared to a particulate catalyst bed.
