Abstract: On the basis of single factor experiment, the influence factors of hydrogen generation of kerosene water reforming were optimized by Box-Behnken mode of response surface method, a quadratic polynomial regression model of reaction was established, and the variance and reliability of the model were analyzed. The results showed that when the kerosene liquid space velocity was 0.066 h^-1, water carbon ratio was 20.2 and the reaction temperature was 681℃, the hydrogen yield achieved the highest level. The predicted maximum hydrogen yield was 33.613 mol/mol, which was almost in consistent with the actual hydrogen yield of 34.028 mol/mol. Therefore, the model was valid and reliable.
