Process for reduction of sulfur content in a hydrocarbon mixture

Abstract

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 ).

1 . Process for the reduction of sulfur content in a hydrocarbon mixture, through catalytic recracking of a fraction of the products generated in the fluid catalytic cracking process, characterized by a product stream to be recracked, injected through one or more injection lines ( 5 ), placed close to the point of gas injection line ( 3 ) that entrains the catalyst in the riser ( 1 ).  
   
   
       2 . Process to reduce sulfur content in a mixture of hydrocarbons, in accordance with  claim 1 , characterized by a stream of products to be cracked having a boiling point within the range of 130° C. and 280° C., preferably within a range between 160° C. and 220° C.  
   
   
       3 . Process to reduce sulfur content in a mixture of hydrocarbons, in accordance with  claim 1 , characterized by a stream of products to be cracked, that is, a mixture of a heavy naphtha cut and a light stream of light cycle oil (LCO).
