Abstract: The present invention relates to the catalytic processes for rendering harmless the flue gases of the power stations or more precisely to the catalysts for sulfur oxides reduction to elemental sulfur. The novel catalyst presents the binary polycations of copper and zinc or copper and manganese incorporated into the low silica faujasite X (LSX) having transition metals ratio Cu:Zn or Cu:Mn in the range of 2:1 to 4:1.

Abstract: An adsorbent separates methanol and other alcohols from gas and liquid oxygenates and hydrocarbon streams with a low silica faujasite (LSX) in a mono-, bi, or tri-cation alkali and/or alkaline-earth metal forms. The LSX has silicon to aluminum ratio from about 0.9 to about 1.15 and an ion exchange degree for each alkali or alkaline-earth metal in the range of about 10 to about 99.9% equiv. The gas streams for treatment include natural gas, individual hydrocarbons, or vaporized alkyl esters of carboxylic acids, or methyl tert-alkyl ethers and their mixtures with hydrocarbons. The liquid streams include liquefied natural gas (LNG), liquefied petroleum gas (LPG), natural gas liquid (NGL), individual hydrocarbons C3-C5, and monomers, alkyl esters of carboxylic acids including methyl acetate, methyl, ethyl, butyl acrylates and methacrylate, methyl tert-alkyl ethers including methyl tert-butyl ether (MTBE) and methyl tert-amyl ether (TAME).
