摘要： 化学工艺学是化学工程与工艺专业的核心课程，其教学长期存在“重流程模拟、轻材料创新”的倾向，学生难以将工艺设计与新型功能材料的发展前沿相联系。本文基于科教融合理念，将本科毕业设计中的科研成果——“卤素功能化多孔有机笼Inner Mongolia University Porous Organic Cage-Cl (IMUPOC-Cl)的合成及其SO2吸附分离性能”转化为综合性实验设计。围绕“烟气脱硫工艺中吸附剂的设计与选型”这一工艺学核心问题，设置了“材料创制→结构解析→性能评价→工艺权衡”四个递进模块。学生通过卤素功能化策略强化材料对SO2的吸附容量，测定不同温度下的吸附等温线并计算吸附焓，对比非功能化材料及CO2吸附行为，进而分析材料疏水性对高湿烟气工艺条件的适配性。教学实践表明，该案例有效打通了“分子设计”与“工艺流程”之间的认知壁垒，培养了学生在功能材料视角下进行工艺创新的能力。

Abstract: Chemical Technology is a core course in chemical engineering and technology programs, however, its instruction has long emphasized process simulation at the expense of material innovation, making it difficult for students to connect process design with advances in functional materials. Guided by the concept of science-education integration, this study transforms an undergraduate thesis research outcome-the synthesis of a halogen-functionalized porous organic cage, Inner Mongolia University Porous Organic Cage-Cl (IMUPOC-Cl), and its performance in SO2 adsorption and separation-into a comprehensive experimental design. Centered on the core process engineering question of adsorbent design and selection for flue gas desulfurization, the design comprises four progressive modules: material creation, structural elucidation, performance evaluation and process trade-off analysis. Through a halogen functionalization strategy, students enhance the material's SO2 adsorption capacity, measure adsorption isotherms at different temperatures, calculate the adsorption enthalpy, compare the results with those of the non-functionalized material and with CO2 adsorption behavior, and thereby assess the material’s hydrophobicity in relation to process conditions for high-humidity flue gas. Teaching practice shows that this case effectively bridges the cognitive gap between molecular design and process flowsheets and cultivates students’ ability to pursue process innovation from the functional materials perspective.
