Method for preparing a Silica Alumina phosphate Molecular Sieve, Methods for preparing a polyolefin and olefin product, and silica Alumina phosphate Molecular Sieve

摘要

This Invention relates to a Molecular Sieve which has acid catalytic sites and a method for maintaining a tamizmolecular acid catalytic sites of silica Alumina phosphate containing uN Mold.The Method comprises producing a Silica Alumina phosphate Molecular Sieve containing a moldey heating the Molecular Sieve in an environment devoid of effective Oxygen conditionsAre you going to maintain or preserve the number of sites catalu00edticosu00e1cidos. The heated Molecular Sieve exhibited at least a peak in the Infrared region in a range of 3630 cm - 1 to 3580 cm - 1.Preferably,The tamizmolecular heated exhibits a total Peak area in the range of 3630 cm - 1 to 3580 cm - 1 of at least 10% of the area of picostotal in a region of infrarrojosde 4000 cm-1 at 3400 cm-1.
