Claims3
A regenerative, reverse-flow pyrolysis reactor comprising,
- (a) first and second reactors, each comprising a unitary reactor bed;
- (b) a mixing region located between the first and second reactors;
- (c) first and second channels located within the first reactor, the first and second channels being thermally-connected, substantially independent flow-paths;
