Among them, the study of "heterogeneous catalytic reaction and reactor oscillation phenomenon" is a very valuable research topic. According to the general law, in a reactor, the input of materials does not change with time, and the output does not change with time, showing a steady state. The research team led by Li Shaofen passed the experimental certificate.

This self-oscillation phenomenon exists in many gas-solid catalytic reactions, and it is also found through experiments that some industrial catalytic reactions adopt forced oscillation operation, which is superior to steady-state operation. Another national natural science foundation project he applied for was the research on tube-wall catalytic reactors. This kind of topic is mostly theoretical discussion abroad, and there are few experimental studies. For diffusion and reaction in porous catalysts

To solve this problem, Li Shaofen and his students put forward an approximate analytical solution of the effective factor. Compared with foreign methods, their method is more accurate, the parameters are easy to determine, and it is very simple. Later, Li Shaofen, with a doctoral student, studied the diffusion of gas in porous catalysts with the viewpoint and method of fractal geometry just developed in the 1970s. This is the first time in China. imagination
