针对大蒜秸秆难利用的问题，对其进行了热解研究，发现生物质内的无机盐确实可以起到热解催化的作用。同时研究了没有催化剂和有催化剂两种情况下的热解行为，发现无催化剂时大蒜秸秆在500~600℃间失重百分比最大，且裂解产油率随着温度升高而增加，在550℃时产油率最高，随后随着温度增加，二次裂解加剧产油率降低；而在 KOH的催化作用下产油率明显增加，产油率几乎增加了15%，但产油率峰值仍在500~600℃。并发现KOH促进大蒜秸秆表面皮下细胞及皮下纤维层进行分解是主要的作用。

We undertook a pyrolysis research on garlic stalks to solve its difficulty in use. We found that the inorganic salts in biomass played an important role in catalytic pyrolysis. Moreover, we studied the pyrolysis behavior under catalyst and catalyst-free conditions. The results showed that the weightlessness rate of garlic stalks was the highest at 550 ℃ under catalyst-free condition. The oil production rate increased with the increase of temperature and reached the peak at 550 ℃. Subsequently, as the temperature increased, the secondary cracking was intensified and oil production rate was decreased. The oil production rate increased significantly (almost 15%) under catalysis of KOH. However, the oil production rate was the highest at 500-600 ℃. What's more, we found that KOH played a major role in promoting decomposition of surface skin cells and subcutaneous fibrous layer of garlic stalks.
