摘要
作为生物质资源中,数量最为丰富的木质纤维素,气化后的"生物合成气"可以被进一步用于合成二甲醚。文章系统地介绍了目前国内外利用生物质气化制备二甲醚的研究状况,对木质纤维素的定向气化、微波裂解气化及气体的重整进行了详细阐述,并比较了木质纤维素合成气一步法合成二甲醚2类典型方法的优劣;最后提出微波裂解气化木质纤维素技术与二甲醚浆态床一步法合成技术相结合制备二甲醚的新思路。
As the main constitute of blomass, lignocellulose was gasified to produce bio-based syngas which can be used to synthesize of dimethyl ether. The status of synthesis of dimethyl ether from biomass both home and abroad in the last two decades was reviewed in detail. The directional gasification and microwave pyrolysis gasification of lignocellulose and the reforming of syngas were explained. Two major techniques of one-step synthesis of dimethyl ether from syngas of lignocellulose were evaluated. Finally, a nov- el process of producing dimethyl ether by combining the microwave pyrolysis gasification of lignocellulose and one-step synthesis of dimethyl ether from syngas in slurry bed was suggested.
