| 摘 要： | 将纳米MgO、Al2O3和ZnO分别添加于超细CaCO3中制备出钙基纳米金属氧化物复合吸附剂,并进行燃煤过程中除砷脱硫的试验研究。结果表明,在Ca/S摩尔比为1.8,燃烧温度为1200℃,纳米金属氧化物的添加量为超细CaCO3质量的8%时,添加了纳米MgO的复合吸附剂除砷脱硫性能最好,比单一的超细CaCO3除砷率和脱硫率分别高出了28.73%和37.21%,表现出同时除砷脱硫的良好性能。 |

Simultaneous Dearsenization and Desulfurization by Calcium-based Nano-metal Oxides Compound Sorbents during Coal Combustion |
|
| Abstract: | A series of calcium-based nano-metal oxides compound sorbents were prepared by doping nano-MgO, Al_2O_3 and ZnO into ultrafine CaCO_3, respectively. The characteristics of dearsenization and desulfurization were investigated during coal combustion. The results showed that the efficiency of dearsenization and desulfurization were increased by 28.73% and 37.21% with calcium-based nano-MgO compound sorbent, when Ca/S molar ratio was 1.8 and combustion temperature was 1200℃. The amount of nano-MgO doped was only 8% of ultrafine CaCO_3 mass. The compound sorbent of calcium-based nano- MgO could be applied to the coal combustion for dearsenization and desulfurization simultaneously. |
