摘要：

The deactivation of ZSM-5, -11, and -48 in the cracking of mixtures of hexane with resp. propylene and hexadiene was measured in an electrobalance, operated in a differential mode and connected with an on-line gas chromatograph. In this way the deactivation of both the cracking reaction and the coking reaction could be observed. The effect of coke is more pronounced on its own rate of formation than on the rate of the cracking reaction, except with ZSM-48. Differences between the behavior of the three catalysts can be related to their structural characteristics. © 1990.
