SIMULATION OF MULTIPLE STEADY STATES IN A POROUS CATALYST DUE TO PHASE TRANSITION

[摘要] References(15)Cited-By(9)From numerical calculations, two of the four multiple steady states (branches A and C) obtained on a biporous Pt/AI2O3 catalyst surrounded by reacting mixture containing saturated vapor of cyclohexene reported in the preceding paper6) can be attributed to the behavior of the catalyst filled with vapor mixture and condensed liquid mixture in its micropores. Stability analysis based on heat generation and heat removal curves without considering phase change in the catalyst interior showed only a single steady state, i.e. the rate of vapor-filled catalyst, while incorporating the effect of phase change on the heat generation curve yielded two steady states which gave good agreement with those of experiments within experimental error.
