Activated carbon is a kind of high-quality adsorbent material with developed pore structure and specific surface area, which is prepared from wood, coal and other carbon-containing organic materials. It is widely used in food, chemical, light industry, pharmaceutical, military, electronics, environmental protection and other industries. With the development of science and technology and society, the application area of activated carbon has been expanding.
Activated carbon micro pore structure catalytic activation technology won the second prize of national scientific and technological progress, marking China's activated carbon research and industrialization level into the world's advanced ranks. Jiang Jianchun, director of the Institute of Forestry and Chemical Industry of the Chinese Academy of Forestry Sciences, told the China Green Times that China is the largest producer and exporter of activated carbon in the world. Activated carbon enterprises are mainly distributed in remote mountainous and forest areas, and are the main source of local economy. This innovative achievement is of positive significance to the improvement of activated carbon production technology, the enrichment of product varieties and the enhancement of product competitiveness.
The innovations of this project mainly include four aspects: innovating and developing the directional control technology of Ultra-micro pore structure of activated carbon; innovating the industrialization technology of selective modification of surface functional groups, realizing the economical and feasible industrial application; inventing the low molecular weight self-forming granulation technology of wood powdery raw materials; directional preparation technicians Integrated innovation and new product creation. The industrialized application of the innovative achievements of this project has made the varieties of activated carbon products in China develop from more than 10 in the 1980s and 1990s to more than 50 now. Some of them have reached or exceeded the international advanced level and entered the international market. This has promoted the upgrading and development of the activated carbon industry in China and realized the high value of waste resources. Utilization and energy conservation and emission reduction.
