Removal of particulates from pyrolytic oil

摘要

A process for producing organic liquid product from solid organic waste. The process comprises pyrolyzing the solid organic waste to produce pyrolysis vapors and solid pyrolysis residue. The solid residue is separated from the pyrolysis vapors leaving entrained particulate matter in the vapor. At least a portion of the pyrolysis vapor is condensed for producing pyrolysis liquid containing entrained particulate matter. The pyrolysis liquid is centrifuged producing a light fraction containing entrained particulate matter, a middle fraction substantially free of particulate matter and a heavy fraction containing entrained particulate matter. The middle fraction is recovered as organic liquid product substantially free of entrained particulate matter. The light fraction and heavy fraction are mixed and filtered. The liquid filtrate produced is distilled for producing additional organic liquid product.
