Abstract
The present invention relates generally to an apparatus for housing a chemical looping process comprising of at least one fluidized-bed combustor reactor, at least one entrained riser, at least one particle separator, optionally at least one particle holding reactor, at least one moving-bed reactor, at least one standpipe, at least one L-valve system for solid flow control and interconnecting sections.
Claims28
A chemical looping system comprising:
- a fluidized-bed combustor reactor comprising a windbox, a heat exchange surface, and an oxidant distribution grid;
- a particle;
- a particle separator;
- a riser;
- a particle receiver;
- and
- a moving-bed reactor;
- wherein the fluidized-bed combustor reactor oxidizes the particle, creates a carrier gas, and the riser transports the oxidized particle and the carrier gas to the particle separator;
- and
- wherein the particle receiver receives the oxidized particle from the particle separator and the moving-bed reduces the oxidized particle in the presence of a carbon-based fuel;
- and
- wherein the riser and the moving-bed reactor share a common wall.
