Abstract: Methanol and/or dimethyl ether is converted into lower olefins by bringing a gas stream containing methanol and/or dimethyl ether into contact with a catalyst which contains an aluminosilicate or gallosilicate containing a divalent metal and which has been obtained by hydrothermal treatment of a solution containing a source of metal oxides using a monohydric alcohol having from 1 to 8 carbon atoms as crystallisation aid.

Abstract: The invention provides a novel highly heat-resistant solid catalyst for the methanation of hydrogen and carbon monoxide into methane. Different from conventional nickel catalysts, the inventive catalyst comprises a binary active ingredient composed of an alloy of nickel and molybdenum and a molybdenum carbide supported on a porous catalyst carrier. The catalyst is prepared by heating a catalyst intermediate comprising the oxides of nickel and molybdenum supported on the carrier in a gaseous mixture of hydrogen and carbon monoxide at 500 DEG -700 DEG C., preferably, following a step of hydrogen reduction at 400 DEG -900 DEG C. The most preferable catalyst carrier is a mixture or a composite oxide compound composed of magnesium and aluminum oxides. The methanation reaction can be carried out with the inventive catalyst at a much higher temperature, e.g. 650 DEG C., than with conventional catalysts so that the heat recovery from the gaseous product is greatly facilitated contributing to the energy economy.

Abstract: A crystalline aluminosilicate having the following empirical formula: xM2O.yM'O.Al2O3.zSiO2.nH2O wherein M is an exchangeable cation selected from the group consisting of alkali metals, hydrogen and mixtures thereof, M' is an alkaline earth metal, x is between 0 and 1.5, y is between 0.2 and 40, z is between 12 and 3000 and n is between 0 and 40 and wherein x+y is 1.2 or more, said aluminosilicate having the X-ray diffraction lines of Table 1 of the specification. The crystalline aluminosilicate material is obtained by providing a reaction mixture containing water, a tetrapropylammonium compound and a source of an alkali metal oxide, an oxide of silicon, an oxide of aluminum and an oxide of an alkaline earth metal and having a composition falling within the following ranges: SiO2/Al2O3 molar ratio: 12-3000 OH-/SiO2 molar ratio: 0.02-10 H2O/SiO2 molar ratio: 1-1000 tetrapropylammonium ion/SiO2 molar ratio: 0.02-2 alkaline earth metal/Al atomic ratio: 0.03-300, and maintaining the mixture at a temperature and for a period of time sufficient to form crystals of the aluminosilicate. The aluminosilicate is useful as catalyst for converting methanol and/or dimethyl ether into lower olefins.

Abstract: The invention proposes a new class of crystalline aluminium silicates and gallium silicates having a crystal structure differing markedly from the conventional silicates with respect to the X-ray diffraction diagrams. The novel crystalline metal silicates are prepared hydrothermically by heating an aqueous mixture, which contains the starting materials for silicon dioxide, aluminium oxide or gallium oxide and alkali metal ions in defined proportions and additionally an aliphatic alcohol, for example n-propyl and n-butyl alcohols, in a defined amount. The crystalline metal silicates prepared in this manner are, in particular after conversion into the proton form by ion exchange techniques, usable as catalysts for the catalytic conversion of methyl alcohol or dimethyl ether in the gaseous form into lower olefins, such as for example ethylene and propylene with high yield and high selectivity.
