Pyrolysis characteristics of pine biomass in a powder-particle fluidized bed

College Marine of Science and Engineering, Tianjin Science and Technology, Tianjin 300457, China

摘要

摘要: 通过冷模实验考察了双颗粒流化床的流化特性。结果表明,在适宜的气速范围内,双颗粒流化床层内部可保持较好的流化状态。松木生物质在粉粒流化床反应器中的热解和催化热解实验结果表明,生物质热解时挥发分的释放存在一个最快的温度区域,生物质中约92%的挥发分在723 K时即可释放完全。773 K时,生物质热解产物中的无机气体(IOG)、低碳烃气体(HCG)和碳氢化合物液体(HCL)的收率之和只有3.1%。随着热解温度的升高,IOG、HCG和HCL的收率均逐渐增加,1 173 K时,其收率之和达到58.7%,且产物主要以CO为主。CoMo-B催化剂可有效促进生物质催化加氢热解产物的二次气相反应,在863 K下可得到6.3%,轻质芳烃化合物(苯、甲苯、二甲苯和萘)是1 173 K下非催化过程的两倍。

Abstract: To investigate the fluidized characteristic of powder particle fluidized bed (PPFB), the experiment of cold model fluidized bed was carried out. The results show that fluidization of PPFB could be maintained when gas velocity is in an appropriate range. Pyrolysis and catalytic pyrolysis of pine biomass was also investigated using the PPFB. It was found that there is a rapid release zone for the volatile during biomass pyrolysis, about 92% of the volatile matter of pine is released at 723 K. The total yield of inorganic gas (IOG), hydrocarbon gas (HCG) and hydrocarbon liquid (HCL) is only 3.1%at 773 K. The yields of IOG, HCG and HCL increase with the increase of pyrolysis temperature. The total yields of IOG, HCG and HCL reach 58.7% at 1 173 K, and the pyrolysis product is almost CO. CoMo-B catalyst greatly promotes the secondary reactions of the primary products of catalytic hydropyrolysis. At 863 K the yield of light aromatic hydrocarbons (benzene, toluene, xylene and naphthalene) is 6.3%, which is 2 times higher than that by using SiO₂ at 1 173 K.
