Conclusions
-
1.
From an investigation of the oxidative regeneration of zeolitic catalysts at temperatures from 620 to 700°C, it has been shown that the reaction of coke burning proceeds in the kinetic region at temperatures below 650°C and in the internal diffusion region at temperatures above 670°C.
-
2.
At gas velocities from 0.7 to 1.4 m/sec. there is no external diffusion retardation in the supply of oxygen to the surface of the coked catalyst particles.
-
3.
Use of the proposed kinetic equation in calculating oxidative regeneration has demonstrated the acceptability of this equation; the error in the determination amounts to ±5.1%.
