采用LZ—1型催化剂对苯酚焦油进行了催化裂解，并通过共沸精馏得到雨酮、α-甲基苯乙烯、异丙苯、苯乙酮、苯酚等其它有用物质。实验结果表明，催化裂解法苯酚的生成率为97．63％。 Phenol tar was catalytically cracked by LZ-1 catalyst, and other useful materials such as ketones, α-methyl styrene, cumene, acetophenone, phenol and the like were obtained by azeotropic distillation. The experimental results show that the formation rate of phenol by catalytic cracking is 97.63%.
