Abstract

The invention provides a multifunctional loaded catalyst, a preparation method thereof, and application of the catalyst to combined removal of CO in flue gas. The multifunctional loaded catalyst comprises a carrier as well as an alkali-based component and a metal active component which are loaded on the carrier. The loaded metal catalyst is modified by the alkali-based component of KOH or NaOH andthe like, so the synergistic effect of CO2 removal and CO removal can be realized. The multifunctional catalyst is simple in preparation method, high in CO2 removal rate and CO catalytic reaction activity, high in stability after long-time use and suitable for CO and CO2 combined removal in fire disaster flue gas of closed space such as a submarine, a space station and a refuge chamber for mining, so that microenvironment purification after the closed space fire disaster is realized. The experiment indicates the multifunctional catalyst provided by the invention can realize synergistic effective removal of high-concentration CO2 (0.5 to 15.0 percent) and CO (0.1 to 0.5 percent) at 0 to 200 DEG C.

Description

technical field

[0001] The invention belongs to the field of micro-environmental air quality control technology and public safety technology, and particularly relates to a multifunctional supported catalyst and its preparation method and the application of combined removal of CO in flue gas. The catalyst can be used to jointly eliminate CO and CO in flue gas 2 , especially suitable for micro-environment purification after fire in closed spaces such as submarines, space stations and coal mine refuge chambers. Background technique

[0002] With the development of social economy and the advancement of science and technology, human beings have increasing demands for space exploration, deep-sea navigation and mining of underground mineral resources. Period persistence. Typical enclosed spaces such as submarines, space stations, and mining refuge chambers are limited in entrance and exit and are relatively isolated from the outside world. In the event of a fire, conventional smok...
