Abstract: To follow the industrial upgrading and transformation of Light Chemical Engineering and to explore the education reform of practice and experimental teaching for students majoring in it under the background of "emerging engineering education", an experimental and practical teaching system to improve students' ability for engineering and innovation majoring in Light Chemical Engineering was developed in Sichuan University based on the long-term practice teaching. Following the organic combination of inheritance and innovation of training objectives, training programs and resource allocation of experimental practice teaching, the "554" collaborative training system, "5+N" experimental practice curriculum system and "3-chain integration" experimental project system for experimental practice ability training were constructed. It provides strong support for improving the training quality of Light Chemical Engineering professionals and promoting the construction of the first-class majors.
