摘要
以木屑热解油为原料,在过硫酸铵(APS)存在下,将预处理的生物油与丙烯酸(AA)和壳聚糖(CTS)聚合,制备出一种生物油基环保新型煤尘抑制剂(Hbio-CTS)。结果表明,在70℃,CTS和AA的质量分别为0.65 g和3.00 g,APS/CTS为5%时,可获得Hbio-CTS的最大黏度,为5.4 mPa·s。Hbio-CTS的FTIR和TG均证实,AA和CTS已成功接枝在生物油组分的结构上。Hbio-CTS在煤粉上形成的固化层受风雨影响很小。其中,在17 m/s(Ⅶ级)风速下,煤粉的最大质量损失为6.99%。经过8个循环(56 d)后,Hbio-CTS的降解率为57%。
Wood chip pyrolysis oil was used as raw material,and the pretreated bio-oil was polymerized with acrylic acid(AA)and chitosan(CTS)in the presence of ammonium persulfate(APS).A new bio-oil-based environmentally friendly coal dust inhibitor(Hbio-CTS)was prepared.The results show that at 70℃,CTS and AA mass is 0.65 g and 3.00 g,when APS/CTS is 5%,the maximum viscosity of Hbio-CTS synthesized under optimized conditions is 5.4 mPa·s.Both the FTIR and TG properties of Hbio-CTS confirmed that AA and CTS had been successfully grafted on the structure of bio-oil components.The solidified layer formed by Hbio-CTS on pulverized coal is very little affected by wind and rain.Among them,at 17 m/s(classⅦ),the maximum mass loss of pulverized coal was 6.99%.After 8 cycles(56 d),the degradation rate of Hbio-CTS was 57%.
