低温等离子改性复合钙基吸附剂烟气脱硫实验研究
Experimental study on desulfurization from flue gas by calcium-based composite sorbent with non-thermal plasma treated
摘要
Abstract
Non-thermal plasma technology has significant modification effect on solid adsorbent surface. In order to study the effect of calcium-based sorbent modified by non-thermal plasma on desulfurization and develop a high efficient desulfurization adsorbent, the calcium-based sorbents with different ratios of activated carbon(AC/CaO)were prepared. The influences of AC to CaO ratio, adsorption temperature,O2 concentration on the desulfurization of calcium based sorbent were studied in a fixed bed adsorption test bench. Under the optimized experimental conditions,the effects of non-thermal plasma modification on the desulfurization were further studied. Results showed that the maximum capacity of per mass calcium-based adsorption for SO2 reached 24.89 mg/g in the optimal experimental conditions,which was greater than the pure CaO. The calcium-based sorbents treated with non-thermal plasma performed higher SO2 removal efficiency. Compared with the unmodified calcium-based sorbent,SO2 adsorption capacity per mass increased by 61.7% through non-thermal plasma modification. There are competitive removal reaction between SO2and NO with calcium-based sorbent,however,it was favorable for SO2 removal after non-thermal plasma modification.关键词
