Abstract: It is important to investigate the catalyst combination and temperature on the preparation of olefins by ethanol coupling.Firstly,ANOVA was used to screen the important influencing factors;then,the importance of the influencing factors on ethanol conversion and C4 olefin selectivity was analyzed by random forest algorithm:temperature>catalyst mass>ethanol concentration>Co loading>charging ratio;finally,multiple non-linear regression was performed by L-M algorithm,and the optimal C4 olefin yield was obtained with particle swarm algorithm.The optimal value was 42.548 5%.

Key words: random forest, L-M algorithm, C4 , olefin preparation, particle swarm algorithm
