Abstract
Lime is incorporated in a heated liquid or semi-solid tar, fuel oil, or bitumen containing tar acids and water under such conditions that at the end of the treatment the free water content of the material is small. An increase in viscosity probably due to the formation of a gel lattice structure is thus obtained. The tar acids may be present in the tar as in the case of continuous vertical retort, and low temperature retort tars or they may be added, as e.g. phenol, as in the case of carburetted water gas tar, horizontal retort tar, coke oven tar, bitumen, and fuel oil. The heat may be provided by preheating the tar to, e.g. 70 DEG C., the heat of reaction sufficing to maintain the temperature. The proportion of lime may be from 1,6 per cent upwards; one example specifying 20 per cent addition. The material produced is thixotropic, viz. it loses its rigidity on disturbance but regains it on standing. The advantages of such a property for fuel oil to be used in the production of "colloidal fuel" is referred to. The treated tar or bitumen may be used as a binder in road construction or in briquetting, or for pipe coatings.ALSO:Lime is incorporated in a heated liquid or semi-solid tar, fuel oil, or bitumen containing tar acids and water such under conditions that at the end of the treatment the free water content of the material is small.
