PHOSPHATE-ZINC MOLECULAR SIEVE AND ITS USE IN ADSORPTION AND CATALTIC REACTION

摘要

PURPOSE: To provide a new crystalline molecular sieve of phosphate-zinc, which is capable of separating O₂, CO₂, N₂, etc., and to utilize it in adsorption and catalytic reaction. ;CONSTITUTION: The molecular sieve has a three dimensional micro-porous framework structure of a tetrahedral unit of ZnO₂ and PO₂, pore system in crystal and an experimental equation of anhyrous base represented, as the ratio of oxides, by formula of rM₂O: sZnO: P₂O₅, wherein M is at least one alkali metal, r is 0.9-1.5 and s is a value of 1.8-3.0. The molecular sieve is made by hydrothermal crystal action of a reaction mixture made by combining phosphorous, zinc, at least one alkali metal and water. The molecular sieve is used adsorption using therefor and hydrocarbon conversion process, etc.;COPYRIGHT: (C)1994,JPO
