Abstract
A technique is described which enables agglomerating coals (caking coals) to be flash pyrolyzed in a fluidized-bed reactor without agglomerates forming in the fluidized-bed. The technique requires the inert particles of the fluidized-bed to be coarser and denser than the particulate coal being pyrolyzed. With this arrangement the momentum of the inert particles in the fluidized-bed is believed to destroy the agglomerates as they form.
