PROCESSES AND SYSTEMS FOR PRODUCING HEAT FOR RAPID THERMAL PROCESSING OF CARBONACEOUS MATERIAL

摘要

Embodiments of processes and systems for producing heat for rapid thermal processing of carbonaceous material are provided. The process comprises the steps of contacting bubbles of an oxygen containing gas advancing through a fluidized bubbling bed with a grating to form smaller bubbles. The fluidized bubbling bed is contained in a reheater and comprises inorganic heat carrier particles and char. The reheater is operating at combustion conditions effective to burn the char into ash and heat the inorganic heat carrier particles to form heated inorganic particles. The heated inorganic particles are advanced to a reactor.
