Abstract:

The new chemical materials are an important part of new materials and the key materials required for national economic construction. The development of new chemical materials has become an important direction for the transformation and upgrading of the refining and chemical industry. The industrial development status of new chemical materials at home and abroad was analyzed in this paper, focusing on the carbon sequestration of renewable raw materials and typical new materials (including high-end carbon materials, automobile lightweight materials, new energy materials and carbon capture materials) from the perspective of the whole life cycle (LCA) of raw material supply, new material production, product recovery and recycling of new chemical materials carbon sequestration in production and carbon reduction in waste material recovery and recycling. The development status and prospect of China's new material industry were analyzed. It was considered that new chemical materials had a significant effect in reducing CO₂ emission and realizing the goal of carbon neutralization. Based on the strong demand of China's new chemical material market, China should increase investment in technology R & D and make breakthroughs technological bottlenecks, accelerate the industrialization of independent products, meet the urgent needs of China's economic development and promote the green, low-carbon and high-quality development of social economy.

Key words: new chemical materials, carbon emission reduction, carbon sequestration of raw materials, carbon sequestration of new materials, product recycling
