Value-Added Utilization of Biomass via Pyrolysis and Catalytic Upgrading

       课题组长期致力于生物质催化热解制备高值化学品的基础与应用研究，核心方向为非原位催化热解技术全流程开发。研究体系基于多元化可再生及废弃可循环碳资源，主要底物包括生物柴油产业副产物粗甘油、非食用性植物油（如蓖麻油、藻油等能源植物油脂）、制浆造纸污泥以及废弃聚烯烃类塑料等。通过分子筛、金属氧化物及复合催化剂的结构设计、反应系统集成及全流程模拟优化，实现目标产物的高选择性可控合成。主要产品定位高附加值的芳烃平台化合物（如苯系物）、C₈-C₁₆长链烷烃及符合航空燃料标准的生物质基航空煤油。

Our research is consistently committed to fundamental and applied research on preparing high-value chemicals from biomass through catalytic pyrolysis. The core direction is the full-process development of ex-situ catalytic pyrolysis technology. The research system is based on diversified renewable and waste recyclable carbon resources. Primary substrates include crude glycerol (a by-product of the biodiesel industry), non-edible vegetable oils (such as castor oil, algal oil, and other energy plant oils), pulp and papermaking sludge, as well as waste polyolefin plastics. By means of structural design of catalysts (zeolites, metal oxides, and composite catalysts), reaction system integration, and full-process simulation and optimization, we achieve the highly selective and controllable synthesis of target products. The main products are targeted at high-value-added aromatic platform compounds (e.g., benzene series compounds), C8-C16 long-chain alkanes, and biomass-based aviation kerosene conforming to aviation fuel standards.
