NOVELTY - Carbonaceous raw materials pyrolysis involves mixing heat exchange particles (25) with a mean temperature (T2) and pyrolysis material (21), where the pyrolysis material is dried. The heat exchange particles and the pyrolysis material are cooled down to a mean pyrolysis temperature (T1). The pyrolysis material is isothermally disintegrated into solid, liquid and gaseous pyrolysis products (29,34), where the gaseous pyrolysis products are exhausted at a pyrolysis temperature. The heat exchange particles are made of hollow bodies filled with a filler material.    USE - Method for pyrolysis of carbonaceous raw materials (claimed).    ADVANTAGE - The carbonaceous raw materials pyrolysis method provides feasible and optimum pyrolysis performance with autothermic partial gasification.    DETAILED DESCRIPTION - Carbonaceous raw materials pyrolysis involves mixing heat exchange particles having a mean temperature and pyrolysis material, where the pyrolysis material is dried. The heat exchange particles and the pyrolysis material are cooled down to a mean pyrolysis temperature. The pyrolysis material is isothermally disintegrated into solid, liquid and gaseous pyrolysis products, where the gaseous pyrolysis products are exhausted at a pyrolysis temperature. The heat exchange particles are made of hollow bodies filled with a filler material, where the filler material undergoes a phase change at a predetermined temperature. The liquid and solid pyrolysis products are partially oxidized under controlled addition of an oxidizing agent (31), where the heat exchange particles and liquid and solid pyrolysis products heat up to a mean temperature. The heat exchange particles are separated and recirculated from the pyrolysis products. An INDEPENDENT CLAIM is also included for an apparatus, which comprises a reaction vessel with inlets, a drying zone, a pyrolysis zone with outlet for gaseous pyrolysis products and a partial oxidation zone with an adjustable oxidant intake.
