Process for fluidized catalytic cracking of disulfide oil to produce ethylene used for metathesis to produce propylene
Relatively low value disulfide oil (DSO) compounds produced as by-products of the mercaptan oxidation (MEROX) processing of refinery hydrocarbon streams, and oxidized disulfide oils (ODSO), are economically converted to value-added light olefins by introducing the DSO and/or ODSO compounds as the feed to a fluidized catalytic cracking (FCC) unit and recovering the light olefins, namely, ethylene and propylene, and in some embodiments a minor amount of butylenes which is then recovered and introduced as the feedstream to a metathesis process for the production and recovery of propylene.
