The production of SiCl4 waste derived from photovoltaic industry in China is very large, due to the high value utilization technology of SiCl4 waste needs further development, we put forward using SiCl4 waste to synthesize solid amine CO2 sorbent used for CO2 capture from flue gas. Using SiCl4 waste to produce nano-silica by low-temperature hydrolysis technology and further synthesize solid amine CO2 sorbent by chemical modification. In this research, we focus on the following studies: investigate the nucleation mechanism of the primary particles, and the forming mechanism of pore structure of nano-silica to realize to control the pore structure of nano-silica and produce high-performance nano-silica; study the core mechanism of synthesis of solid amine CO2 sorbent to synthesize higher-performance of solid amine CO2 sorbent; through study the mechanism of amidation, the toxic mechanism of SO2, NOx, O2and the activation mechanism of vapor to sorbent to develop the solution. Through this research, to provide theoretical basis and technical support for the practical application of SiCl4 waste synthesis solid amine CO2 adsorption materials.
