Abstract

The kinetics of coke combustion, platinum sintering in a non-hydrogen atmosphere, and redispersion on Pt-Sn reforming catalyst were investigated. By using the kinetic results, mathematical simulation of coke burning in a radial continuous regenerator was established. Good agreement was obtained between simulation-calculated and measured temperatures. The oxygen in the gas may enhance resistance to sintering at high temperatures in the presence of water. The sintered platinum on the catalyst, if there had been no decrease of the support surface area, can be completely redispersed through chlorination and oxidation.
