Discharge of CO2 to be Controlled

CO2 is mainly produced during the consumption of energy and it is a major source of greenhouse effect. After many years¡¯ research on the chemical environmental phenomena in incineration, researchers of the Institute of Engineering Thermophysics (IET), CAS first put forward and expounded the integration principle of three separation types of carbon dioxide. Application of this principle will realize 100% O2 capture ratio and 100% injection of CO2, thus solving a big technological problem in the emission reduction of CO2. The US Department of Energy called it a ¡°revolutionary breakthrough¡±. The UN Intergovernmental Panel on Climate Change (IPCC) pointed out in a special report on the capture and injection of carbon dioxide in 2005 that Prof. Jin Hongguang from the Institute of Engineering Thermophysics (IET), CAS, made great contributions to the study on the incineration of chemical scission. Moreover, IET proposed a new way to eliminate the emission of NOX: they use the mechanism of no direct contact of fuel and air and no aphlogistic gas-solid reaction, which fully controls the production of NOX and boasts a significant breakthrough in solving pollution produced by the burning of coal.

On the basis of implementing the project of ¡°Incineration and Comprehensive Disposal of Urban Solids Waste¡±, IET has conducted R&D on direct incineration of raw refuse, control of pollution from incineration and integration of incineration system, built the first 100t/d circulating fluidized bed waste incineration system in China and accomplished the development of circulating fluidized bed waste incineration technology.

¡°Preparation Method of Nano-copper Particles¡± Granted US Patent

The ¡°Preparation Method of Nano-copper Particles¡± co-invented by Liu Weimin and Wang Xiaobo from the State Key Laboratory for Solid Lubrication, Lanzhou Institute of Chemical Physics, CAS and Fu Xingguo from the CNPC Lanzhou Lubricating Oil Research & Development Institute obtained a US patent (Patent No. 7,422,620) on Sep. 9, 2008. This invention features low price and availability of raw materials, simple and convenience, low cost and high yield. The nano-copper particles are 1-10 nanometers in diameter, stable in the air and can be well dispersed in benzene, petroleum ether and other industrial non-polar organic solvent and many kinds of lubricant base oil.
