In order to fully leverage the important role of advanced technology in air pollution prevention and control, noise and vibration control, and synergistic efficiency reduction of pollution and carbon emissions, the Ministry of Ecology and Environment has organized the compilation of the 2024 "National Pollution Prevention and Control Technology Guidance Catalogue (Encouraged Category)" (draft for soliciting opinions), which is now open for public comment.

The encouraged category of the Catalogue for soliciting opinions this time includes a total of 19 technologies, including 6 promotion technologies and 13 demonstration technologies, involving sub fields of air pollution prevention and control such as dust removal, desulfurization and denitrification, VOCs treatment, and odorous gases.

It is worth noting that in the draft of the encouraged "Catalog" for soliciting opinions, low-temperature absorption graded material adsorption oil and gas purification technology, air conditioning workpiece surface vacuum oil removal and recycling technology are listed as promotion technologies; The condensation adsorption catalytic oil and gas recovery and purification technology, functional group grafting modified fiber purification technology for odorous gases, biological odorous gas treatment technology, and plasma coupled spray washing odorous gas treatment technology are listed as demonstration technologies.

Demonstration technology is innovative, with advanced technical indicators and good governance effects, basically reaching the level of practical engineering application, and has engineering demonstration value;

Promotion technology is a mature technology proven through engineering practice, with stable governance effects, economic rationality and feasibility, and encourages the promotion and application.
