PROCESS FOR PROCESSING TALL OIL PITCH, FUEL COMPOSITION COMPRISING TALL OIL PITCH, USE AS FUEL OF A COMPOSITION COMPRISING TALL OIL PITCH AND COMBUSTION PROCESS

摘要

The present invention relates to a process for treating tall oil pitch by decantation comprising a cooling and reheating step, making it possible to separate a light supernatant phase (4) with reduced ash content which can then be subsequently recovered. light (4) forms a combustible composition from biomass which is particularly suitable for being burned in industrial combustion plants.
