Apparatuses and Methods for Controlling Heat for Rapid Thermal Processing of Carbonaceous Material

摘要

Embodiments of apparatuses and methods for controlling heat for rapid thermal processing of carbonaceous material are provided herein. The apparatus comprises a reheater for containing a fluidized bubbling bed comprising an oxygen-containing gas, inorganic heat carrier particles, and char and for burning the char into ash to form heated inorganic particles. An inorganic particle cooler is in fluid communication with the reheater to receive a first portion of the heated inorganic particles. The inorganic particle cooler is configured to receive a cooling medium for indirect heat exchange with the first portion of the heated inorganic particles to form first partially-cooled heated inorganic particles that are fluidly communicated to the reheater and combined with a second portion of the heated inorganic particles to form second partially-cooled heated inorganic particles. A reactor is in fluid communication with the reheater to receive the second partially-cooled heated inorganic particles.

1. An apparatus (10) for controlling heat for rapid thermal processing of carbonaceous material, the apparatus (10) comprising:
a reheater (14) configured to contain a fluidized bubbling bed that comprises an oxygen-containing gas (34), inorganic heat carrier particles, and char and to operate at combustion conditions effective to burn the char into ash and heat the inorganic heat carrier particles to form heated inorganic particles; an inorganic particle cooler (15) in fluid communication with the reheater (14) to receive a first portion (38) of the heated inorganic particles and configured to receive a cooling medium (52) for indirect heat exchange with the first portion (38) of the heated inorganic particles to form first partially-cooled heated inorganic particles (54), wherein the reheater (14) and the inorganic particle cooler (15) are cooperatively configured to combine the first partially-cooled heated inorganic particles (54) with a second portion of the heated inorganic particles in the reheater (14) to form second partially-cooled heated inorganic particles; and a reactor (12) in fluid communication with the reheater (14) to receive the second partially-cooled heated inorganic particles.
