    Abstract: The invention provides a water gas shift process comprising a reaction stage. The reaction stage comprises (a) providing a gas mixture comprising CO, H2O and an acid gas component to a reactor containing an adsorbent, and (b) subjecting the gas mixture to water gas shift reaction conditions to perform the water gas shift reaction. The adsorbent comprises an alkali promoted alumina based material. The acid gas component comprises H2S.

    Abstract: The invention relates to a method for the removal of gaseous organo-sulphur compounds, in particular THT, from fuel gas streams. The method comprises bringing the gas stream into contact with an adsorbent, with a clay mineral from the hormite group, such as palygorskite. attapulgite, sepiolite and paramomtmorillonite as adorbent. In particular, the clay mineral is sepiolit e and the fuel gas stream comprises natural gas. In this way large gas volumes can be purified for a prolonged period with the aid of an environmenetally friendly and inexpensive adsorbent. The invention also relates to a combination of a gas filter based on a clay mineral from the hormite group a nd a fuel cell. The invention also relates to a method wherein the clay mineral has been provided with a metal salt or a metal oxide, or a method wherein th e clay mineral is combined with a second adsorbent.

    Abstract: A process for treating biomass comprises providing a material that contains an amount of residual moisture. The material is heated to a torrefying temperature in a low-oxygen atmosphere in a torrefaction reactor to convert it into a torrefied material. The material with the contained residual moisture is essentially fully dried in a drying chamber by evaporation of residual moisture. The torrefaction reactor comprises a torrefying chamber, in which the torrefaction of this dried material is essentially carried out. The material is conveyed through the torrefaction reactor. The drying of the material in the drying chamber is carried out by introducing into it a hot drying gas that flows therethrough cocurrently with the material. The torrefaction of the material in the torrefying chamber of the torrefaction reactor is carried out by introducing into it a hot torrefying gas that flows through the torrefying chamber countercurrently with the material.

    Abstract: A device for producing a product gas from a fuel, such as biomass, comprises a reactor which is delimited by a base and reactor walls. The reactor walls comprise a peripheral wall and an upper wall. The reactor comprises a supply opening for the supplying of biomass, as well as at least one riser for chemically converting the biomass supplied to a product gas and a solid. The riser is provided inside the peripheral wall and comprises an upper end and a tower end. The reactor furthermore has a discharge opening for discharging the product gas. The riser is attached to at least one reactor wall. The lower end of the riser is at a distance above at least one section of the base which is underneath it and is freely movable under the effect of thermal expansion.
