Abstract: A method for production of hydrogen including reforming of a carbon comprising fuel is provided together with production plants adapted for obtaining hydrogen at lower temperatures and/or higher pressures and obtaining a CO2 rich rest gas stream. A reformer and a water gas shift reactor are also provided.

Abstract: The present invention relates to a catalyst comprising at least one metal loaded on a hydrotalcite-based carrier material which has the following formula in its uncalcined form: M2+aM3+b(An?)(OH)2a+3b?n*xH2O, wherein M2+ is at least one divalent metal; and 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. When said at least one metal is selected from the group VIII of the periodical system of the elements a useful (de)hydrogenation catalyst is achieved.

Abstract: The invention provides a formed heterogeneous catalyst composition comprising a particulate MII(MIII)O (wherein MII and MIII are divalent and trivalent metals respectively) catalyst support and a particulate binder wherein the surface area per unit weight of the support is greater than that of said binder and wherein the compressability of said binder is less than that of said support.

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 process for dehydrogenating dehydrogenatable C.sub.2-30 hydrocarbons includes contacting the hydrocarbons under dehydrogenating conditions in one or more reaction zones with a solid catalyst. The solid catalyst includes at least a Group VIII noble metal, a Group IVA metal, and a carrier of a mixed oxide of magnesium and aluminum.

Abstract: A new catalyst, especially for the dehydrogenation of dehydrogenatable C.sub.2-30 hydrocarbons. The catalyst comprises a carrier consisting essentially of a mixed oxide of magnesium and alumina Mg(Al)O, and also comprises a Group VIII noble metal, a Group IVA metal and optionally a Group IA alkali metal. The catalyst may be subjected to a pretreatment comprising a reduction, a subsequent oxidation and finally a second reduction. The catalyst is particularly suitable for the dehydrogenation of C.sub.2-5 paraffins to olefins, with and without simultaneous oxidation of hydrogen.
