Includes bibliographical references. "A technique to simulate catalyst aging was developed whereby catalyst deactivation is accelerated by changing the operating conditions. Because of greatly accelerated aging, the technique can provide preliminary information on aging rates in a much shorter time than is normally required for performing an actual aging test. This report documents a series of tests performed to investigate the effect of variations in space velocity and temperature. Suitable deactivation conditions were found to prevail when both the space velocity and temperature were increased. In one particular case, this increase accelerated the aging rate about thirty times. The relationship between the aging patterns observed under simulated and actual aging conditions is discussed. An approximate quantitative link was established which provided an estimate of the catalyst aging rate from tests performed at simulated conditions"--Abstract, p. i. Includes abstract in French.
