Abstract

Particulate organic solid waste is pyrolyzed in the presence of an inert particulate source of heat and a carrier gas in a pyrolysis reactor to form a carbon containing solid residue of pyrolysis, pyrolytic oils and gases. The particulate source of heat and carbon containing solid residue of pyrolysis are separated from the product stream. The particulate source of heat and carbon containing solid residue of pyrolysis are transported to a combustion zone where through partial or total combustion. The particulate source of heat is reheated to a temperature requisite for feed to the pyrolysis reactor with attendant generation of additional particulate source of heat.
