Abstract:
Char-handling processes for controlling overall heat balance, ash accumulation, and afterburn in a reheater are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium. The spent heat transfer medium is separated into segregated char and char-depleted spent heat transfer medium. The char-depleted spent heat transfer medium is introduced into a dense bed of heat transfer medium fluidized by a stream of oxygen-containing regeneration gas. All or a portion of the segregated char is combusted in the dense bed using the stream of oxygen-containing regeneration gas. A portion of the segregated char may be exported out of the pyrolysis system to control the overall heat balance and ash accumulation.
