Abstract:

Through simulation aging test in laboratory scale and the industrial device tracking, the influence of H2O content in the regeneration recycle gas on the properties of continuous reforming catalyst was investigated. The results show that the H2O in recycle gas can cause the loss of specific surface area of the catalyst and the increase of the pore diameter of the carrier. The increase of H2O content causes the fast reduction of the specific surface area of the catalyst, resulting in the obvious drop of the chloride retention capability, as well as the reduction of the activity and selectivity of the catalyst.

Key words: continuous reforming, catalyst, H2O, specific surface area
