Abstract:
Hydrogen sulfide evolution in a heavy hydrocarbon (such as a residual fuel oil) derived from a heavy crude oil (such as a API 8 gravity crude) is suppressed by contacting the hydrocarbon with a compound corresponding to the reaction product of a heterocyclic aldehyde (such as furfural) and an organic primary amine.
