在固定床反应器中研究了煤矸石和玉米芯在添加剂作用下的热解行为。结果表明，随着煤矸石掺量的增加，热解过程中液体油产率和气体产率均降低，煤矸石与玉米芯在共热解过程中存在相互作用。与HZSM-5分子筛一样，麦饭石对热解过程也有重要影响，可以提高液体油产率。添加Co/MS、Mo/MS、PW 12/MS、KCl/MS、CaCl 2/MS和Co-Mo/MS可提高油收率，其中Co/MS对液体油性质的改善效果优于其他添加剂。添加CaCl 2/MS和Mo/MS也能提高共热解过程中H2的相对含量。HZSM-5、KCl/HZSM-5、CaCl 2/HZSM-5、SnCl 2/HZSM-5、Co/HZSM-5、PW 12/HZSM-5和Mo/HZSM-5的加入也使500 °C和900 °C共热解过程中液体油产率增加，气体产率降低; Co/MS对液体油性质的影响也优于其他添加剂。
Pyrolysis behavior of coal gangue and corncob with some additives was studied in a fixed bed reactor. The results showed that with the blending ratio of coal gangue increasing during pyrolysis, the liquid oil yield and the gas yield all decreased, and there were interactions between coal gangue and corncob during co-pyrolysis. Furthermore, the results also showed that just as HZSM-5, medical stone (MS) also had an important influence on the pyrolysis process and could increase the liquid oil yield. Adding Co/MS, Mo/MS, PW12/MS, KCl/MS, CaCl2/MS and Co-Mo/MS could increase the oil yield, and Co/MS had a better effect on liquid oil properties than other additives. Adding CaCl2/MS and Mo/MS also could increase the relative content of H2during co-pyrolysis. Adding HZSM-5, KCl/HZSM-5, CaCl2/HZSM-5, SnCl2/HZSM-5, Co/HZSM-5, PW12/HZSM-5 and Mo/HZSM-5 also made the liquid oil yield increase and the gas yield decrease during co-pyrolysis at 500 °C and 900 °C; and Co/MS also had a better effect on liquid oil properties than other additives.
