  • Patent number: 11331623
    Abstract: 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.

  • Patent number: 9932229
    Abstract: The present invention relates to a process for producing a hydrogen containing gas mixture comprising the following steps: (i) providing a preheated mixture comprising a fossil fuel, preferably methane, and steam, (ii) conducting an adiabatic reaction between the fossil fuel and the steam, in the presence of a catalyst, wherein a first reaction product mixture is formed comprising methane, hydrogen and carbon dioxide, and (iii) conducting an oxygen-assisted reforming reaction in the presence of a catalyst between said first reaction product mixture and an oxygen comprising stream, wherein the oxygen comprising stream comprises at least 40 vol % oxygen, forming a second reaction product mixture comprising hydrogen and carbon monoxide. The invention also relates to a system suitable for hydrogen production from a hydrocarbon feed according to the present invention.

  • Patent number: 9102532
    Abstract: Method for producing synthesis gas for methanol production The present invention relates to a method for producing synthesis gas from a hydrocarbon containing feed, which synthesis gas is particularly suitable for subsequent use in methanol production. In this method, a feed (100) is divided into two streams, wherein one stream is subjected to catalytic partial oxidation (CPO) (2) and the other stream is subjected to steam reforming (5) followed by a water gas shift reaction (51). The two streams are then recombined and can be used further in methanol synthesis (6). The recombined stream preferably has an R ratio, being a molar ratio (H2?C02)/(CO+C02), in the range of 1.9-2.2 and preferably about 2. The invention further relates to a method for producing methanol from a hydrocarbon containing feed, wherein first synthesis gas is obtained according to the method of the invention, which synthesis gas is further used to produce methanol.
