    Abstract: A hydrotalcite-based material having an improved mechanical strength, said hydrotalcite having the following general formula: M2+aM3+b(OH)c(An-)d*xH2O wherein M2+ is at least one divalent metal; M3+ is at least one trivalent metal; A is an n-valent anion, n is 1 or 2 and a and b are positive numbers, a>b, which hydrotalcite is deposited on alumina or an alumina precursor, a process of preparing said hydrotalcite-based material, the use thereof as a catalyst support material, a catalyst for the dehydrogenation of propane, and a process using such a catalyst in the dehydrogenation of propane.

    Abstract: A method of reforming a feed gas comprising natural gas and/or a prereformed natural gas, water vapour and an oxygen-containing gas in an autothermal reactor, characterised in that by the feed gas is first passed through a catalyst free zone in the reactor, in which zone the feed gas is partially combusted in an exothermic oxidation reaction and partially reformed, that the hot, partially combusted and reformed gas is led further through a catalyst bed for further reforming, so as to form a reformed gas stream, and that the reformed gas stream is separated into a first stream primarily containing H2 and a second, low hydrogen stream primarily containing CO2, water vapour and CO, any inert gases and some unconverted feed gas, by means of a membrane in the catalyst bed, which membrane is permeable to hydrogen. A reactor for implementing the method is also described.

    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.
