Abstract
Embodiments of the disclosure provide a method and system for upgrading heavy hydrocarbons. A heavy hydrocarbon feed and a non-saline water feed are introduced to a first stage reactor. The first stage reactor is operated under supercritical water conditions to produce an effluent stream. The effluent stream and a saline water feed are combined to produce a mixed stream, where the saline water feed includes an alkali or alkaline earth metal compound. The mixed stream is introduced to a second stage reactor. The second stage reactor is operated under supercritical water conditions to produce a product stream including upgrading hydrocarbons. The second stage reactor is operated at a temperature less than that of the first stage reactor.
