The way of resource utilization of carbon dioxide driven by double carbon goal

With the progress and development of chemical technology, the chemical synthesis of carbon dioxide as a raw material is gradually expanding the application field and product range.

Using carbon dioxide as raw material, ethanol, acetic acid, MDI, acrylate, long chain dibasic acid can be synthesized. These areas have already been industrialised and are gradually growing in scale. The downstream of ethanol is mainly used as industrial raw materials, and the downstream of acetic acid is mainly used to produce acetic anhydride, acetic ester and cellulose acetate. Polyvinyl acetate can be made into films and adhesives, and is also a raw material for synthetic fiber Vinylon, cellulose acetate can be made into rayon and motion picture film.

The new chemical production with carbon dioxide as raw material, the representative products are: polyhydroxyaliphatic acid, 1, 3-propylene glycol, adipic acid, polylactic acid, lysine, butanol, succinic acid, caprolactam, ethyl acetate and so on. These products have been achieved bio-based chemical production, carbon dioxide can be used as an intermediate raw material.

With the development of the industry, the application of carbon dioxide in the chemical industry has gradually increased, the production scale has been expanding, and the production cost of some processes has also been gradually reduced, slowly replacing other chemical production methods. In the future, in some subsectors, the net zero emission of carbon dioxide in the integrated production process can be achieved through the resource utilization of carbon dioxide, which will help accelerate the realization of the dual-carbon goal.
