This work comparatively studied the catalytic effect of MgO and MgCO on pyrolysis of rice husk (RH). The apparent activation energy (E) was reduced significantly by pyrolysis of RH with MgCO, thus lowering the decomposition temperature during pyrolysis. MgO could not obviously influence the gas evolution during pyrolysis, while MgCO had a better performance on the syngas (H and CO) generation at around 600-700 °C. Also, the generation of CO was suppressed by the RH pyrolysis with MgCO. The phenols were the dominant compounds in the bio-oil derived from RH. Furthermore, co-pyrolysis of RH and polyvinyl chloride (PVC) in the presence of MgO or MgCO at 600 °C could improve the oils quality by decreasing the acids content and increasing the hydrocarbons content. Particularly, the resulting oils had high hydrocarbons content (>35%) and low acids content (<2%). The decrease of acids, alcohols, and phenols contributed to the increase of hydrocarbons.
这项工作比较研究了 MgO 和 MgCO 对稻壳（RH）热解的催化作用。MgCO 的 RH 热解使表观活化能（E）显著降低，从而降低了热解过程中的分解温度。MgO 不能明显影响热解过程中的气体逸出，而 MgCO 在 600-700°C 左右对合成气（H 和 CO）的生成具有更好的性能。此外，MgCO 的 RH 热解抑制了 CO 的生成。酚类是 RH 衍生生物油中的主要化合物。此外，在 600°C 下，MgO 或 MgCO 存在下 RH 和聚氯乙烯（PVC）的共热解可以通过降低酸含量和增加烃含量来改善油的质量。特别是，所得到的油具有高的烃含量（>35%）和低的酸含量（<2%）。酸、醇和酚的减少有助于烃的增加。
