Abstract
Phenols are removed from phenol-containing liquors or effluents such as gas liquors and condensates from coal distillation or cooling waters for generator gas prepared by gasifying anthracite or lignite by treatment with a water-immiscible solvent for phenols such as benzene, commercial benzole or tar oil so as to extract a large part of the phenols followed by a treatment with an adsorbent charcoal such as active carbon or bone black to extract the remainder of the phenol. In a preferred manner of carrying out the process tar oil is sprayed into the liquors and the separated liquor filtered through active carbon. The active carbon may be revivified. The Provisional Specification refers also to the use of any solid adsorbent. Specification 266,004, [Class 2 (iii), Dyes &c.], is referred to.ALSO:Phenols are removed from phenol-containing liquors or effluents, such as gas liquors and condensates from coal distillation or cooling waters for generator-gas prepared by gasefying anthracite or lignite, by treatment with a water-immiscible solvent for phenols such as benzene, commercial benzole or tar oil so as to extract a large proportion of the phenols followed by a treatment with an adsorbent charcoal such as active carbon or boneblack to extract the remainder of the phenol.
