| 英文摘要 | In the present study, the spent fluid catalytic cracking (FCC) catalyst is regenerated via coke gasification instead of combustion in a micro fluidized bed reactor to investigate its reaction characteristics and kinetic parameters. The reaction rate first increased with carbon conversion ratio and then slowly decreased when reaching the peak. H2 and CO was found to be over 70 vol.% in the gasification gas. Two reaction models, homogenous model (HM) and shrinking core model (SCM) were used to calculate the kinetic parameters of catalyst regeneration, finding that HM had better fitting relevance for the data than SCM. The activation energy from these two models was close to each other, that is, about 150 kJ.mol-1 for the coke gasification over FCC catalyst. 漏 2015 Published by Elsevier Ltd. |
