SYSTEMS AND METHODS FOR PARTIAL OR COMPLETE OXIDATION OF FUELS

摘要

A system used for converting multiple fuel feedstocks may include three reactors. The reactor system combination can be so chosen that one of the reactors completely or partially converts the fuel while the other generates the gaseous product required by utilizing the gaseous product from the second reactor. The metal-oxide composition and the reactor flow-patterns can be manipulated to provide the desired product. A method for optimizing the system efficiency where a pressurized gaseous fuel or a pressurized utility is used for applications downstream can be used to any system processing fuels and metal-oxide.

1. A system for the production of syngas, comprising:
a first reactor comprising a plurality of oxygen carrying particles comprising a first metal oxide, wherein the first reactor is configured to provide a counter-current contact mode between the first metal oxide and a first fuel to reduce the first metal oxide to a second metal oxide; a second reactor in communication with the first reactor, the second reactor configured to oxidize the second metal oxide to a third metal oxide, and further configured to reduce the third metal oxide to a fourth metal oxide with a second fuel to provide a partially or fully oxidized gaseous fuel comprising one or more of CO, CO2, H2, and H2O, wherein the second metal oxide is oxidized to the third metal oxide using an enhancing gas of CO2 and H2O, the partially or fully oxidized gaseous fuel, or a combination thereof, to generate syngas; and a third reactor in communication with the second reactor, the third reactor configured to regenerate the first metal oxide by oxidizing the fourth metal oxide with an oxygen source.
