Abstract Coal pyrolysis and volatiles upgrading were intelligently coupled into an integrated reactor with two sections that enabled tar quality to be improved. The upper drop tube served as the rapid pyrolysis section to maximize the primary yield of tar. Subsequently, the pyrolysis char together with the released volatiles was introduced into the lower moving bed section, wherein the formed char bed was endowed with a catalytic upgrading function by enhancing volatiles-char interactions. This design succeeded in the consecutive pyrolysis-upgrading process by recombining its pyrolysis products. In the first-step rapid pyrolysis, a much higher yield of tar than the Gray-King assay yield was obtained at 600 °C, but the light fraction (boil pointing

一种提高煤焦油质量的集成反应器串联热解升级策略

摘要 煤热解和挥发分提质智能耦合到两段一体化反应器中，提高焦油质量。上滴管用作快速热解部分，以最大限度地提高焦油的初级产量。随后，热解焦与释放的挥发物一起被引入下部移动床部分，其中形成的焦床通过增强挥发物-焦炭相互作用而被赋予催化升级功能。该设计通过重新组合其热解产物，在连续热解升级过程中取得了成功。在第一步快速热解中，在 600 °C 下获得的焦油产量比 Gray-King 测定产量高得多，但轻馏分（沸点）
