Abstract

A pyrolysis chamber includes a bath of molten salt divided by a horizontally disposed baffle into an upper layer and a lower layer. Connected to one end of the chamber is a furnace including submerged burners for heating the salt and for maintaining it in its molten state. The molten salt flows from the furnace across the upper bath layer and back to the furnace in the lower layer. Hydrocarbon containing material is fed onto the upper bath layer and is pyrolyzed as it moves toward the discharge end of the chamber where the spent material is removed; the hydrocarbon gases being recovered by an exhaust system in the chamber. The molten salt acts as a seal between the atmospheres of the furnace and the pyrolysis chamber and also functions to remove pollutants from the combustion gases of the burners in the furnace.
