| 摘 要： | 基于生物质焦油氧含量高、品质差的缺陷，本文提出将生物质与重油共转化利用的方法。以催化裂化油浆（FCC）、稻壳（RH）、木屑（PS）为原料，通过低温固定床热解实验对其共热解产物分布进行了研究。结果表明，在FCC的供氢作用下，共热解有利于焦油中含氧化合物的脱除，随着生物质比例增加，反应过程中脱羧基、脱羰基反应减弱，脱羟基反应增强，产物中CO、CO2产率较计算值增加幅度减小，水的产率较计算值逐渐增大。焦油中烃类物质增加，其中芳香烃以二元环和四元环增加为主，脂肪烃中以C13~C20增加为主。整体上，共热解过程促进了半焦产率的增加，焦油产率虽无明显改变但品质得到了显著提升。

| Abstract: | Based on the defects of high oxygen content and poor quality of biomass tar, this paper proposes a method for co-conversion and utilization of biomass and heavy oil. The distribution of co-pyrolysis products of FCC slurry (FCC), rice husk (RH) and wood chip (PS) was studied by fixed bed pyrolysis at low temperature. The results show that the co-pyrolysis process is not conducive to the formation of tar in general, and the polymerization reaction in the system is strong, which promotes the increase of char yield. However, under the action of hydrogen supply by FCC, co-pyrolysis is beneficial to the removal of oxygen-containing compounds in tar. With the increase of biomass ratio, decarboxylation and decarbonylation reactions were weaken and dehydroxyl reaction was strengthen in the reaction process, and the increase of CO and CO2 in the product decreases compared with the calculated value, while the yield of water gradually increases compared with the calculated value. The increase of hydrocarbons in tar is dominated by the increase of two-rings aromatic and four-rings aromatic in aromatic hydrocarbons and the increase of C13-C20 in aliphatic hydrocarbons. The quality of tar was improved after co-pyrolysis. |
