摘要:

能源和环境是当今世界的两大挑战,将生物质转化为燃料和化学品是应对该挑战的低碳方案。其中,催化热解木质素获得燃料和化学品是低碳方案的重要部分。本文以能源和环境问题为出发点,阐述了木质素催化热解制备燃料和化学品的可行性和必要性,并对催化裂解行为、催化裂解过程和催化产物等方面的国内外研究现状进行了系统介绍。文章首先对木质素的结构和转化过程进行了概述;然后从催化热解行为、催化热解产物以及催化剂的研究现状等方面进行了系统阐述,并对现有的催化木质素热解过程的机理研究进行了讨论。通过对木质素催化热解制备燃料和化学品的发展前景、技术瓶颈以及逻辑方面进行评估表明,木质素转化为燃料和化学品过程中提高产品的产率和能量效率是今后的总体目标,而原料供给和生产、催化剂开发、产品分离纯化、反应机理和动力学以及计算模拟等方面将是深入研究木质素高效利用的重要研究内容。

Abstract:

Energy and environment had been become the two major global challenges in the present world. The production fuels and chemicals from lignin may be an important part of the low-carbon solution to both issues. This paper took the energy and environmental problems as the starting point, the feasibility and necessity of the production of fuel and chemicals via catalytic pyrolysis lignin were described, and then the status of the research on the catalytic pyrolysis behavior, catalytic pyrolysis process and catalytic products at home and abroad were systematically introduced. A brief introduction of the structure and transformation process of lignin was presented. Then the catalytic pyrolysis behavior, catalytic pyrolysis products, and the research status of the used catalysts were systematically elaborated, and the existing mechanism of catalytic pyrolysis lignin was discussed. The assessment of the challenges and opportunities, mitigating technical, environmental, and logistical issues in the process of catalytic pyrolysis lignin for the fuel and chemicals production showed that improving product productivity and energy efficiency in the conversion of lignin into fuel and chemicals will be the overall goal in the future, and the raw material supply and production, catalyst development, product separation and purification, reaction mechanism and kinetics, and computational simulation will be important research fields for further study on effective utilization of lignin.

Key words: lignin, biomass, fine chemicals, catalytic pyrolysis, hierarchical molecular sieves
