    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 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 for autothermal or substantially autothermal catalytic dehydrogenation of hydrocarbons is described. A hydrocarbon containing feed gas is optionally mixed with steam and/or hydrogen, is pre-heated and is introduced into a catalytic bed of a reactor, where an oxygen containing gas is fed directly into the catalytic bed from one or more oxygen supply tube(s) (3) each tube (3) having one or more opening(s) distributed in the catalytic bed.
