| Abstract: | This paper discussed the effect of regeneration temperature and time, oxygen concentration and flow rate of regeneration gas on the performance of regenerated MTP catalyst. The changes of the regeneration conditions in the experimental ranges did not change the crystal structure of the catalyst. The optimized regeneration conditions are as follows: 500-600℃and 6-9h, oxygen concentration in regeneration gas ≥9.19% and regeneration gas flow rate of 1500-2100mL/(g.h). |
