Abstract
Chemical looping systems and methods for producing hydrogen gas are described herein that use a fluidized-bed reactor to reduce carrier particles; and a moving-bed hydrogen reactor to oxidize the reduced carrier particles and form hydrogen gas. Also possibly included as a cooler for cooling the oxidized carrier particles; and a silo for storing the oxidized carrier particles and feeding them to the fluidized-bed reactor and other components. Various configurations of these components are disclosed herein.
Claims23
A system, comprising:
- a fluidized-bed reactor in which carrier particles are reduced;
- and
- a hydrogen reactor with a steam inlet, in which the reduced carrier particles are oxidized and hydrogen gas is formed.
An apparatus, comprising:
- a fluidized-bed reactor in which carrier particles are reduced;
- a hydrogen reactor with a steam inlet, in which the reduced carrier particles are oxidized and hydrogen gas is formed;
- a cooler in which the oxidized carrier particles are cooled;
- and
- a silo configured to receive the oxidized carrier particles from the cooler and feed the oxidized carrier particles to the fluidized-bed reactor.
A method for producing hydrogen (H2) gas, comprising:
- feeding a fuel into a fluidized-bed reactor, the fluidized bed comprising carrier particles that are reduced in the fluidized-bed reactor;
- passing the reduced carrier particles into a hydrogen reactor;
- and
- feeding steam into the hydrogen reactor to oxidize the reduced carrier particles and form the hydrogen gas.
