    摘要: 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 (3) are introduced in an intermediary region of the stripper (1) 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.

    摘要: A process for reduction of sulfur content in a hydrocarbon mixture, without considerable increase in gas production, comprising the introduction of a fraction of products obtained by the FCC process in a reaction zone of said unit. The cut must be introduced into the unit riser, in an area below the feed line of the heavy hydrocarbon streams to be cracked. Preferably, through one or more injection lines (5) placed near the point of gas injection line (3) entraining the catalyst in the riser (1).
