Abstract: A reactor and a process for fluid catalytic cracking (FCC) a hydrocarbon feed in the riser-reactor, the process including injecting the hydrocarbon feed into an evaporation zone of the riser-reactor, injecting a first catalyst into the evaporation zone, wherein the first catalyst mixes with the hydrocarbon feed to generate a hydrocarbons stream in the evaporation zone, and wherein the temperature in the evaporation zone is less than 625° C., and passing the hydrocarbons stream from the evaporation zone into a cracking zone of the riser-reactor to generate a cracked product in the cracking zone.
