Abstract

A process for the dry distillation of used rubber in a fluidized bed-forming oven comprises heating used rubber under agitation in the presence of solid particles to temperatures sufficient to make the rubber pulverized and further heating the thus-obtained rubber particles to temperatures sufficient to pyrolyze the rubber particles while forming a fluidized bed thereof and burning a part thereof in the stream of an oxygen-containing fluidizing gas.
