The rapid development of the chemical industry has contributed to global economic growth and improved people's quality of life. However, the massive consumption of fossil fuels in the chemical production process has also caused environmental pollution and climate change that cannot be ignored. Academician Min Enze has been committed to directional fundamental research in green chemistry since 1990. He has introduced and integrated new materials, processes, and reaction pathways into the traditional petrochemical industry, led and guided the implementation of multiple major national basic research projects, accumulated new technological knowledge in green chemistry, laid the foundation for green refining and petrochemical new processes, and developed multiple influential green chemical technologies, effectively promoting the development of green technologies in the petrochemical industry. This article summarizes the green chemical technology practice cases formed on the basis of the catalytic new materials and green chemistry new knowledge laid by Academician Min Enze in the past 20 years, including the green production technology of caprolactam, fluidized bed hydrogen peroxide technology, complete technology of epoxy propane production by hydrogen peroxide method, and green synthesis technology of cyclohexene esterification and hydrogenation. These condensed innovative practices and experiences in catalytic materials and chemical engineering will provide a foundation and reference for us to carry out new technological innovations.
