Abstract

204,976. Richards, W. E. W., and Siluminite Insulator Co., Ltd. Dec. 19, 1922. Pitch and tar. - Coal tar is heated to about 100‹ C, sulphuric acid is added and air is blown in; heating is then discontinued and the blowing maintained until the mixture has thickened when pitch separates at the bottom and oils at the top, these being separated. The oils are distilled at about 400‹ C a pitch like residue and a distillate suitable for use as fuel oil being obtained. Specification 3008/12 is referred to.
