| 摘要 |
The invention relates to a method for pyrolysis of carbonaceous raw materials. The aim of the invention is process optimization for isothermally performing the pyrolysis with autothermic partial gasification. The aim is achieved by a method comprising mixing heat exchange particles (25) having a mean temperature T2 and pyrolysis material (21); drying the pyrolysis material, wherein the heat exchange particles and the pyrolysis material cool down to a mean pyrolysis temperature T1, wherein T1 is less than T2; isothermally disintegrating the pyrolysis material into solid, liquid, and gaseous pyrolysis products (29, 34) and exhausting the gaseous pyrolysis products at a pyrolysis temperature T1 +/- 10°C, wherein the heat exchange particles are made of hollow bodies filled with a filler material and the filler material undergoes a phase change at T1; partially oxidizing the liquid and solid pyrolysis products under controlled addition of an oxidizing agent (31), wherein heat exchange particles and liquid and solid pyrolysis products heat up to a mean temperature greater than or equal to T2; and separating the heat exchange particles from the pyrolysis products and recirculating (36) the heat exchange particles to the mixture. |
