         The zeolite-containing FCC catalyst produced by Lanzhou Refinery was steam deactivated at temperature in the range of 700~850℃ for 2~20 hrs. Results show that the steam deactivation is a first-order decay reaction, at the lower temperature region, the deactivation is chiefly due to changes in matrix, and at the higher temperature region, it is chiefly due to changes in zeolite.
