Abstract

The present invention refers to a method and an equipment for pyrolytic treatment of organic material comprising a supply storage receiving the organic material to be treated, a number of containers with meshlike walls, each to be charged with a batch of said organic material, a horizontal reactor with a charge gate in one end and a discharge gate in the opposite end, the interior of the reactor being divided by means of internal gates into at least a heating chamber, a pyrolysis chamber, and a cooling chamber, as well as a recovery storage for a solid pyrolytic residue of the organic material, i.e. the pyrolytic coke, the pyrolysis chamber being provided with an outlet pipe for generated pyrolytic gas terminating in a fractionating condenser, said condenser being provided with an outlet for each liquid fraction and an outlet pipe for uncondensed pure pyrolytic gas, which outlet pipe terminates in a gas tank.
