两种活性焦脱除烟气中SO2及水洗再生性能对比分析

利用2种原煤制得的活性焦进行烟气脱硫并对脱硫后的活性焦水洗再生试验进行研究。研究发现，高变质煤制备的活性焦NM吸附SO2能力及水洗再生性能均高于低变质煤制备的活性焦SX。水洗再生试验表明，SX活性焦用纯水再生，再生率可达32．67％。用适量碱液再生，再生率可达55．04％，NM活性焦用纯水再生，再生率可达82．43％，用适量碱液再生，再生率可达97．2％。分析焦样发现，碱液再生后SX活性焦平均孔径和比表面积均降低，而碱液再生后的NM活性焦平均孔径和比表面积均有增加。

Comparative analysis of washing regeneration performance and removal of SO2 using two kinds of activated coke

Study the desulphurizing effect of active coke which were made of two kinds of raw coal and the washing regeneration performance after desulfurization. The results show that the capacity of SO2 adsorption and washing regeneration performance of active coke NM which is made of high rank coals is better than active coke SX which is made of low rank coals, with water recycling the regeneration rate of active coke SX is up to 32.67% while active coke NM is up to 82.43% ,with the amount of lye Regeneration the rate of active coke SX is up to 55.04% while ctive coke NM is up to 97.2%. Average pore and surface area of active coke SX were lower after alkaline regeneration while the situation of active coke NM was opposite.
