Problems solved by technology

[0002] With the progress of society, the demand for energy is increasing, and the large-scale use of energy will inevitably have a greater impact on the environment. Due to the constraints of domestic resource protection capabilities and environmental capacity, as well as global energy security and climate response, resource and environmental constraints are increasingly strengthened. Among them, coal It is one of the very important energy sources, but coal is discharged directly without full combustion, which not only causes a waste of resources, but also produces a large amount of harmful gases, causing air pollution and threatening people's living environment

Abstract

The invention discloses a porous catalyst comprising a carrier composed of alumina and silica; the carrier is coated with a metal compound; based on the total weight of the catalyst, the content of the carrier is 94%-97%, and the content of the metal compound is 3%-6%; the carrier has the properties of enough specific surface area, high thermal stability, and firm heat load generated in the fuel oxidation reaction process, so the properties can ensure long-term chemical and mechanical stability, the porous catalyst can be used for any burning materials, improves heat quantity, effectively reduces generation of harmful gases, and allows the burning materials to have the advantages of energy saving and environmental protection.

Description

technical field [0001] The invention relates to the field of energy technology, more specifically, it relates to a porous catalyst. Background technique [0002] With the progress of society, the demand for energy is increasing, and the large-scale use of energy will inevitably have a greater impact on the environment. Due to the constraints of domestic resource support capabilities and environmental capacity, as well as global energy security and climate response, resource and environmental constraints are increasingly strengthened. Among them, coal It is one of the very important energy sources, but if the coal is not fully burned, it is directly discharged, which not only causes a waste of resources, but also produces a large amount of harmful gases, causing air pollution and threatening the living environment of people. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a porous catalyst t...
