Title:
METHOD FOR PREPARING DENITRATION ANTI-SULFUR CATALYST GROWN IN SITU ON NITROGEN-DOPED GRID MACROMOLECULES
Document Type and Number:
WIPO Patent Application WO/2021/128814
Kind Code:
A1
Abstract:
A method for preparing a highly-efficient denitration anti-sulfur catalyst-loaded nitrogen-doped grid macromolecule-based composite material, comprising: first, by means of adding metal salts, aggregating a large number of Ce3+, Ce4+, Sn3+ and Sn4+ ions around cyanuric acid molecules; then, adding 2,4,6-triaminopyrimidine and cytosine, and enabling same to have a grafting reaction with cyanuric acid, so as to generate N-doped macromolecules in a first stage; then, using potassium permanganate as an oxidant, and carrying out an oxidation-reduction reaction on the surface of the N-doped macromolecules, so that a manganese-cerium-tin catalyst is grown in situ on the surface of the N-doped macromolecules; and finally, performing calcination once, such that the N-doped macromolecules are cross-linked, and finally a composite material having a denitration anti-sulphur catalyst grown in situ on N-doped grid macromolecules is generated. The composite material has higher denitration anti-sulfur properties.
