    摘要： An aluminum-containing substrate is described that comprises at least one superficially applied microporous layer of an aluminum phosphate zeolite (ALPO) as well as other layers. Said aluminum-containing substrate is characterized in that the microporous layer of the aluminum phosphate zeolite represents a primer coating on which a microporous or mesoporous secondary material is located which differs from the material of the primer coating. Said aluminum-containing substrate is produced in a particularly advantageous manner according to a method in which 1. an aluminum-containing substrate is hydrothermally treated in an aqueous suspension containing at least phosphorus as a network-forming element, and a microporous primer coating of an aluminum phosphate zeolite is formed on the substrate by means of an in situ crystallization process, especially the molar ratio between the network-forming aluminum that is deficient in the aqueous suspension and the sum of all network-forming elements in the aqueous suspension being less than 0.5 such that the aluminum required for compensating the deficiency is removed from the aluminum-containing substrate, and 2.; a microporous or mesoporous secondary material is formed on the microporous primer coating by subjecting the aluminum-containing substrate that comprises the microporous primer coating to another treatment in an aqueous suspension containing the network-forming elements required for forming the porous secondary material. The described aluminum-containing substrate is particularly suitable as a heat exchanger, as a catalytic reactor, or as a component in heat transformation technology with an anti-corrosive or anti-fouling effect.

    摘要： A solvothermal synthesis process of the SAPO molecular sieves and catalysts prepared thereby are provided. The synthesis process comprises the following steps: a) an organic amine, an aluminum source, a phosphorus source, a silicon source, and water are mixed in a molar ratio of 6-30:1:0.5-5:0.01-1.0:0.1-15, to obtain an initial mixture for preparing the SAPO molecular sieves, wherein the molar ratio of water to the organic amine is less than 2.0; b) the initial mixture obtained in the step a) is maintained at 30-60° C. to and aged with stirring for not more than 24 hours, to obtain an initial gel; c) the initial gel obtain in the step b) is crystallized at 150-250° C. for 0.5-15 days. The SAPO molecular sieves prepared thereby are used, after being calcined at 400-700° C. in air, as catalysts for acid-catalyzed reactions or for conversion reactions of oxygen-containing compounds to olefins.

    摘要： A SAPO-34 molecular sieve and method for preparing the same, whose chemical composition in the anhydrous state is expressed as: mSDA.(SixAlyPz)O2, wherein m is 0.08-0.3, x is 0.01-0.60, y is 0.2-0.60, z is 0.2-0.60, and x+y+z=1. The template agent SDA is in micropores of the molecular sieve. SDA is an organic amine with the structural formula (CH3)2NRN(CH3)2, wherein R is a saturated straight-chain or branched-chain alkylene group with having from 2-5 carbon atoms. There is a slight Si enrichment phenomenon on the crystal surface of the molecular sieve crystal, and the ratio of the surface Si content to the bulk Si content of the crystal ranges from 1.50-1.01. Said SAPO-34 molecular sieve, after being calcined at a temperature range from 400-700° C. in air, can be used as a gas adsorbent and catalyst for an acid-catalyzed reaction or oxygenate to olefin reaction.
