Disclosed is a catalyst suitable for the catalytic oxidative cracking of a HS-containing gas stream. The catalyst comprises at least one or more active metals selected from the group consisting of iron, cobalt, and nickel, supported by a carrier comprising ceria and alumina. The active metal is preferably in the form of its sulphide. Also disclosed is a method for the production of hydrogen from a HS-containing gas stream, comprising subjecting the gas stream to catalytic oxidative cracking so as to form Hand S, using a catalyst in accordance with any one of the composition claims.

Catalyst for catalytic oxidative cracking of hydrogen sulphide with concurrent hydrogen production

A catalyst composition suitable for the ethanol reforming process at low temperature with enhanced stability on long term, comprises a noble metal, such as platinum or rhodium, and a transition non-noble metal, such as nickel or cobalt, supported by a carrier comprising, cerium, zirconium, optionally aluminium, supplemented with potassium. It is provided also a method for the stable production of hydrogen from an ethanol containing gas stream, comprising subjecting the gas stream to catalytic ethanol reforming as to form a rich H2 stream, using the catalyst as defined above.

Catalyst for low temperature ethanol steam reforming and related process

Disclosed is method for removing carbonyl sulphide and/or carbon disulphide from a sour gas stream. The method comprises subjecting the gas stream to simultaneous contact with an absorption liquid, such as an aqueous amine solution, and with a catalyst suitable for hydrolyzing carbonyl sulphide and/or carbon disulphide. To this end, the invention also provides a reactor system wherein both an absorption liquid and a catalyst are present. In a preferred embodiment, the catalyst is a heterogeneous catalyst present on or in an absorption column, either coated on the trays of a column with trays, or contained in the packing of a packed column.

COS and CSabatement method

An apparatus for carrying out endothermic reactions including a plurality of catalytic vessels, immersed in a combustion chamber having a contiguous overlaid convection chamber enclosing a top portion of the catalytic vessels wherein heat is recovered at a lower temperature level from the flue gases from the combustion chamber. The catalytic vessels may contain internal and coaxial heat recovery tubes creating an annular space filled in with a catalytic device. Both the external heat recovery through the catalyst tube outer surface and the internal heat recovery through the inner tube surface can be maximized by an enhanced catalytic device acting also as a heat transfer promoter in the process gas region. The apparatus provides enhanced and flexible heat recovery that permits to meet the request of minimum or none export steam production in one single apparatus, avoiding the need of a pre-reforming section and/or of a convective reformer downstream.

Enhanced efficiency endothermic reactor for syngas production with flexible heat recovery to meet low export steam generation

Method for stable ethanol steam reforming, wherein a catalytic ethanol reforming is carried out in two vessels operating in parallel mode both filled in with a catalyst active for this reaction, with the first vessel acting in operation mode, generating an hydrogen rich stream, and the parallel vessel, acting in regeneration mode, made flowing with steam in order to carry out the gasification of carbonaceous compounds deposited on the catalyst.

Method for stable ethanol steam reforming

Disclosed is a method for the production of hydrogen from a HS-containing gas stream also containing ammonia, comprising subjecting both gas stream to catalytic oxidative cracking of both the HS and the NH, so as to form H, Sand N. In this method, preferably, an additional amount of oxygen is added as compared to the amount used for H2S catalytic oxidative cracking. Also, preferably, the contact time of the gas stream with the catalyst is increased. The catalyst preferably is provided as a single bed, and then preferably comprises iron and molybdenum supported by a carrier comprising aluminum. The preferred carrier is alumina. The iron and molybdenum preferably are in the form of sulfides.
