It is reported that according to the "Kyoto Protocol" of the United Nations Framework Convention on Climate Change, the CDM targets six types of greenhouse gas emissions including carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. International environmental protection standards promote energy saving and emission reduction in all countries, and reduce the global green-house gas emissions of environmental protection.
Li Yongjun, a member of the CDM Global Environmental Protection Fund, said that as of February 2008, there were 1,087 CDM projects registered in the world, of which 650 were in the energy industry, accounting for 59.8%, which is the highest in all fields, which means energy industry. In particular, renewable energy has become the mainstream of CDM, and it has great potential for development. The CDM market in developing countries with a high level of industrialization has great potential. From the perspective of the CDM projects that have been registered successfully in the United Nations globally, by February of this year, the most registered of the China Merchants (developing countries) was 389 in India. 214 and 115 in Brazil.
In recent years, the pace of renewable energy development in China has accelerated significantly. In September 2007, the Chinese government issued the "Mid-term and long-term development plan for renewable energy," and clearly stated that renewable energy consumption will reach 10% of total energy consumption by 2010, and will reach 15% by 2020.
It is understood that the National Development and Reform Commission has approved more than 1,000 CDM projects, including 214 successful registrations at the UN. More and more companies have gradually become aware of the CDM projects. The world-famous carbon finance companies have come one after the other. Domestic chemical companies such as fluorine chemicals, chlor-alkali chemicals, and coal chemical companies have become direct beneficiaries of the CDM.
As an excellent high-temperature engineering material, Si3N4 ceramic block has the most advantage in its application in high temperature fields. The future development direction of Si3N4 is: (1) to fully utilize and utilize the excellent characteristics of Si3N4 itself; (2) to develop some new flux during the sintering of Si3N4 powder, to study and control the optimal composition of existing flux; (3) to improve milling , molding and sintering process; (4) development of Si3N4 and SiC and Other Materials, in order to obtain more high-performance composite materials.
