Abstract:
1. A method for the integration of carbochlorination into a staged reforming operation, the method comprising: step i. delivering a feedstock to a thermal decomposition stage where the feedstock is reacted with a gas and volatized through a plurality of thermochemical steps to yield a gas stream and a solid residue comprising a spent catalyst, an inert mineral, and a formed coke; step ii. chlorinating the solid residue in a carbochlorination process to produce a gas comprising carbon oxides and a multi-phase residue comprising a molten or semi-molten salt, metal, or metal compound; step iii. reacting water and a portion of the gas stream of step i. in a hydrogen production process to produce a carbon gas comprising hydrogen, wherein at least a portion of the multi-phase residue is used as a heat carrier between the carbochlorination process and the hydrogen production process; step iv. delivering at least a portion of the gas produced in step ii. or step iii. to the thermal decomposition stage of step i. to be used as the gas reacted with the feedback; and step v. delivering at least a portion of the gas stream formed in step i. to a downstream process.
