摘要
Abstract
Specific surface area and pore size distribution of fly ash/Ca（OH）2 hydro-absorbent prepared under different conditions were measured, and effects of different preparation conditions on simultaneous removal of NO2 and SO2 was investigated in a fixed-bed reactor. The results reveal that Ca-based absorbent with higher specific surface area and more abundant porosity structure can be achieved from the hydrothermal reaction of Ca（OH）2 with fly ash in slurry. The higher hydration temperature, the longer hydration time, the appropriate ratio of fly ash to Ca（OH）2 and solid to liquid, the lower dry temperature are beneficial for the forming of high specific surface area and abundant porosity structure of absorbent, also for the enhancing of reaction activity in simultaneous removal of NO2 and SO2.关键词
