在解耦双循环反应系统中,进行了以石英砂-赤铁矿为床料的白松木屑热解和热解油催化提质研究.通过颗粒分级器,将循环床料石英砂和赤铁矿分别分配到热解器和提质器,构成原料热解-半焦燃烧和热解油催化提质-床料再生两个独立、平行的反应回路,实现了各反应的解耦调控.考察了热解温度、赤铁矿/生物质比(H/B)、提质温度对热解产物的影响.结果表明,提高热解温度有利于白松木屑热解脱氧,油产率在500℃时达到峰值.H/B增大促进了热解油的脱羧和脱羰反应,有效降低了其中酯类、酸类、酮类的含量,进而富集了芳烃、糠醛类等高值化学品.提质温度升高使热解油中各种含氧化合物(除酚类)相对含量均处于较低水平,而芳烃相对含量增加,最高可达35.6％.
