Development and Application of Gas Flow Bubbling Generator

With the continuous consumption of global fossil resources, the conversion of renewable resources has become the focus of scientific researchers. The catalytic conversion reaction of bio-based lower alcohols obtained by the biological or chemical conversion of biomass is a hot research topic in recent years. In order to efficiently explore a variety of model catalytic reactions, a gaseous flow bubbling generator is developed to replace the feeding process of the traditional fixed-bed reactor. The purpose is to carry out different model catalytic reaction exploration experiments. By comparing the experimental results of the two equipments, it is shown that the gas flow bubbling generator has the characteristics of small error, fast test and simple operation. In addition, the advantages of its small footprint and portability are just right for a variety of in-situ characterization techniques. By combining the gas flow bubbling generator with the in-situ diffuse reflection infrared spectroscopy, students are able to study the theoretical knowledge of the infrared spectroscopy and the working principles of instruments, and integrate the basic knowledge on catalysis that have learned. The gas flow bubbling generator not only assists the exploration of scientific research experiments, but also can be extended to the application of experimental teaching, which improves students’ scientific research innovation ability, and provides a new paradigm for the integration of science and education and the integration of teaching and research.
