Process for stripping oil from fluidized ash and char particles to prepare the particles for decarbonization

摘要

A mixture of a high density particulate inorganic heat source and a low density particulate carbon containing residue formed in the pyrolysis of a solid waste is passed along with some entrained pyrolytic oil to a fluidized bed of particles, where a gas is injected to strip the entrained pyrolytic oil from the particles, and a mixture of a high density particulate heat source and low density particulate carbon containing solid residue of pyrolysis are separated from an intermediate point of the fluidized bed and passed to a decarbonization zone, where the carbon containing solid residue of pyrolysis is decarbonized to form a high density particulate inorganic solid heat source for use as the source of heat in the pyrolysis of organic solid waste.
