The demand for olefin is increasing in countries. At present, prince's principle is mainly used for catalytic coupling ethanol to prepare olefin. This method is cheaper and greener, but there are many problems in the process of preparing olefin. The influence of temperature on ethanol conversion and C4 olefins selectivity was studied by nonlinear regression simulation [1]. Then, the grey correlation degree analysis was used to establish the grey prediction model, and the ranking of the influence of each factor on ethanol conversion was temperature, ethanol concentration, etc., and the ranking of the influence of each factor on C4 olefins selectivity was mass[2], HAP total mass, ethanol flow rate, etc. Finally, the optimum temperature and catalyst combination of olefin preparation were analyzed.
