ABSTRACT The catalysts for use in pyrolytic decomposition of the phenol distillation residue in accordance with the present invention are used in pyrolytically decomposing a distillation residue resulting from the separation by distillation of cumene, phenol and acetone from a reaction mixture obtained by oxidizing cumene with molecular oxygen followed by acid cleavage, and the present catalysts are characterized by comprising oxygen containing metallic compounds having a particle diameter of 0,002-100 µm. Furthermore, the processes for recovering useful substances from a phenol distillation residue containing the same in accordance with the present invention are characterized by allowing said phenol distillation residue to undergo pyrolytic reaction at a temperature of 200- 350°C, preferably 250-300°C, in the presence of the above- mentioned oxygen containing metallic compound catalysts having a particle diameter of 0.002-100 µm, thereby recovering the useful substance such as cumene, phenol and the like from the phenol distillation residue.
