模块知识融合反应工程大作业设计的思考

Considerations in Designing Course Projects of Reaction Engineering Based on Module Knowledge Fusion

化学反应工程是高校化学工程专业的重要核心课之一,致力于研究化学动力学并根据反应特点设计合适的反应器。课程教学团队根据多年教学经验,将课程内容分为理想反应器、非理想流动、非均相催化和工业反应器四个模块,并针对非理想流动与非均相催化模块的知识关联较弱而导致学生无法综合运用所学知识解决复杂反应工程问题的现象,设计了基于模块知识融合的课程大作业。本文阐述了课程大作业对加强模块间知识关联的重要作用,梳理了课程大作业的设计和实施要点,并以催化剂氧空位测量的课程大作业为例,介绍如何通过非理想流动和非均相催化模块知识的融合提升学生解决复杂工程问题的能力,最后总结了课程大作业实施过程中的共性问题并提出了改进建议。

Chemical reaction engineering,which focuses on studying chemical kinetics and designing appropriate reactors according to reaction characteristics,is one of the core courses in Chemical Engineering in colleges and universities.Based on years of teaching experience,the contents of this course are divided into four modules:ideal reactors,nonideal flow,heterogeneous catalysis,and industrial reactors.However,the weak correlation between the nonideal flow module and the heterogeneous catalysis module makes students unable to comprehensively apply the basic knowledge of the two modules to solve complex reaction engineering problems.Aiming at this problem,course projects based on module knowledge fusion is designed.The important role of course projects in strengthening the knowledge connection between modules is elaborated and the main points of the design and implementation of course projects are sorted out.Taking a course project for measuring the quantity and reactivity of oxygen vacancies in a catalyst as an example,we explore how to improve students'ability to solve complex practical problems by combining the module knowledge of nonideal flow and heterogeneous catalysis.Finally,the common problems in the implementation of course projects are summarized and suggestions are proposed for continuous improvement.
