摘要
以原煤、煤焦油、沥青和活性炭粉为原料制备了颗粒脱硫脱硝活性炭,考察了不同活性炭粉添加量对再造粒强度及其脱硫性能的影响规律。研究表明,随着活性炭粉添加量的增加,再造脱硫脱硝活性炭的耐磨强度和耐压强度整体呈现下降趋势;脱硫值随活性炭粉添加量的增加而逐渐增大;本试验活性炭粉配煤混合粉中炭粉添加占比为15%~23%的情况下可制备出产品性能优良、资源回收利用率高的脱硫脱硝活性炭,对应的耐磨强度、耐压强度和脱硫值区间分别为97.01%~97.40%、56.63~63.57 daN和28.92~29.54 mg/g。
Activated carbon for granular desulfurization and denitrification was prepared from raw coal, coal tar, asphalt and activated carbon powder. The effects of different activated carbon powder additions on the reconstituted strength and desulfurization performance were investigated. The research showed that with the increase of the amount of activated carbon powder, the wear resistance and compressive strength of the reconstituted desulfurization and denitration activated carbon showed a downward trend. The desulfurization value increased gradually with the increase of the activated carbon powder amount. The desulfurization and denitration activated carbon with excellent product performance and high resource recovery rate can be prepared under the condition that the carbon powder in the mixed coal powder was 15%-23%. The corresponding wear resistance, compressive strength and desulfurization value range were 97.01%-97.40%, 56.63-63.57 daN and 28.92-29.54 mg/g, respectively.
