Abstract Microwave-assisted catalytic fast co-pyrolysis (co-MACFP) of distillers dried grains with solubles (DDGS) and waste agricultural plastic mulching films (WAPMFs) with SiC as microwave absorbent and hierarchical ZSM-5/MCM-41 as catalyst are implemented in a microwave-induced reactor. MCM-41 mesoporous structure is formed in hierarchical ZSM-5/MCM-41 catalyst as the outer shell layer coupled with ZSM-5 as the inside core. Experimental results show that the use of both microwave absorbent and hierarchical ZSM-5/MCM-41 catalyst significantly increase the carbon yield of hydrocarbons in bio-oil. The influence of co-MACFP temperature and the mass ratio of WAPMFs to DDGS (W/D ratio) on product distribution and hydrocarbon composition is investigated. The total liquid yield and total hydrocarbon carbon yield in bio-oil first increase with the augment of temperature from 500 to 650 °C, and then decrease when temperature continues to rise. Besides, a higher W/D ratio can favor bio-oil production and retard coke formation, and a significant synergy between DDGS and WAPMFs is observed during co-MACFP. Additionally, from the perspective of hydrocarbon carbon yield in bio-oil, W/D ratio of 1.0 is the best option.

使用微波吸收剂和分级 ZSM-5/MCM-41 催化剂通过微波辅助催化快速热解，从含可溶物的酒糟 (DDGS) 与废弃农用塑料地膜共同喂养生物燃料

摘要 采用微波辅助催化快速共热解 (co-MACFP) 的可溶物 (DDGS) 和废弃农用塑料地膜 (WAPMFs) 以 SiC 为微波吸收剂和分级 ZSM-5/MCM-41 为催化剂在微波感应反应器中。MCM-41介孔结构以分级ZSM-5/MCM-41催化剂为外壳层，ZSM-5为内核。实验结果表明，微波吸收剂和分级ZSM-5/MCM-41催化剂的使用显着提高了生物油中碳氢化合物的碳产率。研究了 co-MACFP 温度和 WAPMFs 与 DDGS 的质量比（W/D 比）对产物分布和烃组成的影响。生物油中总液体产率和总烃碳产率随着温度从 500 ℃升高到 650 ℃先增加，然后随着温度继续升高而降低。此外，较高的 W/D 比有利于生物油的生产和延缓焦炭的形成，并且在 co-MACFP 期间观察到 DDGS 和 WAPMF 之间的显着协同作用。此外，从生物油中碳氢化合物的产率来看，W/D 比为 1.0 是最佳选择。
