IMPERIAL

PATENT OFFICE.

The invention relates to a method for the production of artificial fuels Coal and the like are known, coal waste with tar and tar residues, oils 5 or the like and to incorporate lime, gypsum, cement, etc. with the addition of water. The invention consists of a special way of mixing the individual substances mentioned together, which results in the most intimate possible mixing of the various dry ingredients both with oil and with Water should be made possible.

The procedure is as follows:

The dry ingredients, e.g. B. coal, gypsum, lime, cement, sawdust and sand, are first intimately mixed with one another; then you divide the whole amount in two same parts. The water is then added in a certain ratio to one part of the mixture while to the other part the oil is added. One part of the mix is now using vigorously worked through the water, the

the other part with the oil until both have a completely even distribution of the oil in question Binder is achieved. Then both parts are brought together and intimate with one another mixed and well worked through.

After the parts are so mingled together, the molten pitch or resin becomes added and the whole mass carefully stirred and worked through until one is perfect uniform composition of the whole mass is achieved.

The fuel is molded into suitable pieces or blocks as appropriate for the particular one Purpose respectively Appear suitable for the oven.

The mixing ratio can be, for. B. be the following: 20 percent water, 8 percent Sawdust, 12 percent mineral oil, 6 percent lime or cement, 6 percent plaster, 6 percent Pitch, 6 percent resin, the rest coal or the like. When producing a fuel with lower oil content, higher coal content and no sawdust the following ratios give good results:

16 percent water, 67 percent coal, 3 percent gypsum, 3 percent pitch, 3 percent Resin, 5 percent oil, 3 percent cement.

As a result of the fact that the mixture of the dry ingredients divided and the one Part with water, the other with oil, can be done with either oil or that Water combine completely with the dry parts of the mixture with which it is worked through. If one were to add the oil and water to the total mixture of the dry components, so would such an intimate mixing or blending as necessary for the present purposes is, cannot be achieved, because if one of the two substances (oil or Water) is added to the mixture before the other, it would reduce the absorption

or prevent intimate interference from the other. Finally, if one wanted to try to add oil and water at the same time, a similar success would result.
Since, according to the present method, the oil is completely absorbed by one part and the water is completely absorbed by the other part of the mixture, the oil will be formed during the subsequent mixing of the two parts

ίο and the water intimately and thoroughly evenly brought into contact with each other.

The fuel produced is relatively hard and does not crack easily, even not when it cracks ruthless treatment, it also does not disintegrate while burning.

Instead of incorporating the pitch or resin at the end of the "ready mix," it can also be added to the part to be made with oil. The moldings are advantageously in the hot state with a Coating surrounded by lime, which then hardens. ■

Claims (1)

Patent claim: Process for the production of artificial fuel from coal pebbles and the like. with the simultaneous use of plaster of paris, lime or cement, water, mineral oil and pitch or resin as binders, thereby characterized that one part of the well mixed dry ingredients with oil, the other with water is worked through well, whereupon the two masses' united and with pitch or resin be mixed.
