脱挥发分作用 devolativation
At lower temperature there exists devolatilization reaction in swelling coal, and it exists a relationship between the swelling ratio and the activation energy, the higher the swelling ratio the smaller activation energy.
溶胀煤在低温阶段有脱挥发分反应,活化能与溶胀效果成对应关系,溶胀率越高活化能越小。

粒径对脱挥发分的影响不是很明显,只当海藻粒径小于0.20mm时,裂解最终残留量略有增加,粒径过小,不仅降低了挥发分还提高了破碎成本。 随着升温速率的增加,TG和DTG曲线均向高温侧移动。
