Abstract
316,897. South Metropolitan Gas Co., Pickard, H., and Stanier, H. March 3, 1928. Drawings to Specification. Tar oils.-Substitutes for the tar-bitumen mixtures used in road-making and like operations are obtained by dispersing bituminous coal, peat, or analogous material in coal tar at 250-350‹ C. so that the product contains no more than 15 per cent of coal &c. and has a consistency lower than 100 secs. Hutchinson at 122‹ F. and upwards. In an example, 6 lb. of Durham coal are dispersed at 300‹ C. in 94 lb. of horizontal retort tar free from water and more volatile oils and of S.G. 1.20; or 30 lb. of coal are dispersed in the tar, and then further tar added at 150-200‹ C. to give a product containing 6 per cent of coal. The Specification shows how to ascertain readily the proportions &c. required to obtain a product of a desired consistency at a given temperature by use of the logarithmic graph of the temperature-consistency relationship of the tar used. According to the Provisional Specification the viscosity and elasticity of coal oils, tars, and pitches are modified by dispersing therein the necessary proportions of naturally occurring carbonaceous substances such as peat and coal at 200-350‹ C. or other high temperature below that causing decomposition of the materials. Specifications 17799/96, 2292/02, [both in Class 55, Gas manufacture], 131,588 and 268,372 are referred to.
