PROCESS FOR THE DISTILLATION OF DECANTED OILS FOR THE PRODUCTION OF PETROLEUM PITCHES |
摘要 |
This invention describes a process for the distillation of decanted oil to improve the efficiency of the production of pitches having excellent physical and chemical properties through the development of a distillation process which basically comprises the introduction of a stage of condensation of light volatile compounds derived from distillation of the decanted oil, causing these light compounds to be recycled to the hot zone of the still and react with the raw material acting as a solvent phase which has a lower viscosity than the reaction system, within a particular temperature range and for a particular time.
