Abstract
A process and device to optimize the yield of fluid catalytic cracking products through a reactive stripping process are disclosed. One or more hydrocarbon streams () are introduced in an intermediary region of the stripper () of a fluid catalytic cracking unit (FCC), from a device that allows a homogeneous distribution with adequate dispersion. This/these stream(s) react(s) with the catalyst of FCC, although its activity is reduced due to the adsorption of hydrocarbons in the reaction zone, generating products that improve and/or change the global distribution of products, providing a refinery profile adequate to meet quality demands and requirements.
