Abstract: The main purpose of innovation experiment is to cultivate students’ innovative thinking ability, so the research content of popular scientific research field is one of the main sources of innovation experiment. Based on the existing hot scientific research, which allows students to use their professional knowledge to understand the scientific problems and technical difficulties, trains their scientific awareness to find solutions, is conducive to increase students’ sense of professional identity and sense of pride. Therefore, based on the major national demand for carbon emission reduction, the undergraduate innovation experiment is conducted with the absorption method of organic amine in carbon capture technology as the content, mainly focusing on the influence of different proportions of alcohol and water as solvents on the absorbent viscosity and CO₂ absorption rate in the development of non-aqueous absorbent. In the process of the experiment, the students’ practical ability and data processing ability are improved. In the result analysis, the influence of absorbent viscosity on the gas-liquid mass transfer process is analyzed by combining the chemical principle and reaction engineering professional knowledge, so as to cultivate the students’ independent thinking ability and innovative thinking ability in an all-round way.
