The mathematical model for dehydrated kinetics of ethanol over HZSM 5 zeolite has been established based on experimentally determined data of ethanol dehydrated kinetics by using microreactchromatography. It is shown by results from statistical analysis that parameter estimates and the mathematical model selected are very approximate. Standard deviation σ and correlation coefficient r 2 are 0.008 744 67 and 0.999 803 2, respectively. It indicates that the mathematical model is accurate and it can represent the real processes of ethanol dehydrated over HZSM 5 zeolite.
