Procedure

According to A.C. CCCP 1235860 (1986) before decomposition, the phenol tar is diluted by high-molecular weight aromatic compounds such as Baltic shale oil (grade kerogen -70) weight ratio of tar to shale oil 1.3/2.5. Process conditions are: pressure 3-7 MP, temperature 400°-430 ° C., time 5-20 min. Liquid products obtained are separated by distillation. This process takes place under relatively severe conditions and gives a poor yield of phenol (4-5% ) and cumene (10-15% ). In addition it requires the addition of shale oil.
