Abstract

The invention relates to a formula and preparation technology of a granular non-noble-metal efficient integrated air purification composite material, and belongs to the technical field of adsorption catalysis and air pollution treatment. The composite material is characterized by taking zeolite, meerschaum, a porous active carbon material, iolite or a self-made carrier as a catalyst carrier, taking one or several non-noble-metal oxides as an active component and a nitrogen-containing organic auxiliary agent, and being prepared through an immersion method. The catalyst has a column granular shape, and has the capacity of the non-noble-metal oxides being 12-15 wt% and the content of the nitrogen-containing organic auxiliary agent being 2.0-4.0 wt%. The material can effectively adsorb and purify formaldehyde, TVOC, benzene, toluene, xylene, ozone, sulfur dioxide, nitrogen dioxide, hydrogen sulfide and ammonia gas in air in an integrated manner at normal temperature and humidity, and the overall purification rate is no less than 95%. The material is suitable for places, such as offices, office buildings, living rooms, shopping malls, hospitals and hotels, for integrated air purification.

Description

technical field [0001] The invention relates to the preparation of a granular non-noble metal high-efficiency integrated air purification composite material, relates to the technical field of adsorption catalysis and air pollution control, and belongs to the collaborative adsorption and catalysis of various non-noble metal oxides for various gaseous pollutants in the air. Background technique [0002] Since the 1970s, in western developed countries, people who live and work in comfortable buildings are usually plagued by unexplained illnesses, such as headaches, dry eyes, dizziness, nausea, difficulty concentrating, and sensitivity to smells, etc., and once Soon after leaving the building, these unbearable phenomena will disappear automatically, and the researchers call it "sick building syndrome" (SBS). Through continuous follow-up tests by scholars from various countries, it was finally discovered that indoor air pollution is behind the disease. [0003] Indoor air pollut...
