    Abstract: A method is described for conversion of natural gas or other fossil fuels to higher hydrocarbons, comprising the following steps: a) reaction of natural gas with steam and oxygenic gas in at least one reforming zone in order to produce a synthesis gas consisting primarily of hydrogen and CO, in addition to some carbon dioxide; b) passing said synthesis gas to a Fisher-Tropsch reactor in order to produce a crude synthesis stream consisting of lower hydrocarbons, water and non-converted synthesis gas; c) separation of said crude synthesis stream in a recovery zone, into a crude product stream mainly containing heavier hydrocarbons, a water stream and a tail gas stream mainly containing the remaining constituents; which is charaterized in that the method also comprises the following steps; d) stream reformation of at least part of the tail gas in a separate steam reformer; e) introduction of the reformed tail gas into the gas stream before this is led into the Fischer-Tropsch reactor.

    Abstract: A process for the production of methanol and/or dimethyl ether and/or other xygenates thereof, a H2-rich and a CO2-rich stream and an integrated plant for the production in said process of methanol and/or dimethyl ether and/or other oxygenates thereof, a H2-rich and a CO2-rich stream. The use of H2 formed by a shift reaction in a shift reactor for the reduction of CO and CO2 in a methanol synthesis reactor is disclosed.

    Abstract: The present invention comprises a composition for reducing the sulphur content in a hydrocarbon composition, wherein the composition comprises a hydrotalcite material, which has been impregnated with a Lewis acid, and optionally a FCC-catalyst. The hydrotalcite material impregnated with the Lewis acid has been added as a separate component, or incorporated in the matrix of the FCC-catalyst. The Lewis acid is selected from the group comprising elements and compounds of the transition metals, and preferably Zn, Cu, Ni, Co, Fe and Mn, most preferably Zn. Further, the Lewis acid may also be selected from the group comprising elements and compounds of the lanthanides and actinides. The present invention also comprises a method for reducing the sulphur content in a hydrocarbon composition. A method for reducing the sulphur content in a hydrocarbon composition, which is to be cracked, is also described. Further, the use of a composition comprising a hydrotalcite material, which has been impregnated with a Lewis acid and optionally, mixed with a FCC-catalyst, is also included.
