SMO KELESS BBIQUET AND PROCESS OF MAKING SAME;

fspecification of Letters Patent.
To all whom it may concern:
Be itknown that l, Bonner A. CARTER, J12, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Smokeless Briquets and Processes of Making the Same, of which the following is a specification.
This invention relates to smokeless briquets and the process of making the same out of substantially a waste product, or a by-product of comparatively little value, in the manufacture of gas for domestic and manufacturing purposes.
The coke which is obtained from the destructive distillation of coal in'the manufacture of gas is more. or less broken and pulverized as the result of handling to get the same from the retorts to the consumer. This coke is quite brittle and portions of it are pulverized or broken into fine particles known in the art, while. in other localities there is a market for it at a very low figure, By my invention I take this breeze or screenhugs and mix with it any suitablepartially volatilizable binder to-form a briquet and then subject the briquet to volatilization to drive out all volatile matter and gases of the. hinder, the resulting briquet being practically smokeless.
If the briquets are not subjected to volatilization the gases of the binder are given ofi' quicklywhen the briquets are fed to a boiler or a stove, resulting in the smoke or gases being under considerable pressure which, when used for instance in domestic service, will'cause the smoke and volatile I gases to-be forced out through the crevices and cracks of the stove besides forming soot within its drafts, passages and connect ing pipes. This objection applies also more or less to the use of'such briquets as fuel for boilers for manufacturing purposes.
By my invention I take the breeze or screenings of coke which is approximately in some instances there is no 10% to 20% or more, of the total output of coke, depending upon how it is handled, and mix with it any suitable binder to make the briquets which may be given any desired shape or contour. In practice '1 have found that a very good binder is ordinarily coal tar pitch, very satisfactory results being obtained with pitch which is known as. 170, the same being its melting point, though of course, it is to be understood that my invention is not limited to this or any other particular form of binder. *I preferably mix the binder in a condition sufficiently fluid to enable it to be at least partially absorbed by the porous particles of the breeze and when the briquets are subsequently coked this absorption insures. a

permanent adhesion between the coke particles and the binder whereby a briquet substantially uniformly coked throughout is produced and crumblingand waste prevented. After the breeze or screenings are .mixed with the suitable binder and given a proper shape or configuration, depending upon the use to which it is to be put, I place the resulting briquets in a volatilizer and subject them to suiiicient heat. to drive otf substantially all the volatile matter of the binder. This leaves the resulting briquets more or less porous and it the volatilization is continued,'the relatively small portion of the binder, which is left in the briquet is very hard. In this second treat ment of the screenings or breeze what little volatile matter remains in it from its first destructive distillation is driven ed with the volatile matter of the binder, the resulting briquet being comparatively firm and burning substantially without smoke.
I have described this invention in connection with one manner of practicing the same but it is to be understood that m invention is not to be limited to the details here set out for what is claimed as new and what it is desired to secure by Letters Patent is set forth inthe appended claims.
1. A porous smokeless briquet comprising coke screenings or breeze and a vola'tilized binder formed frorn'coal tar pitch of sub} stantially 170 melting point combined with the breeze and coked.
2, The method of making smokeless briquets consisting in mixing ordinary coal tar pitch of substantially 17 0 melting point with the breeze or col-re screenings and subfluid to enable it to be at least partially absorbed by the porous particles of the breeze, shaping the briquets, subjectin the briquets to volatilization to drive 0 the volatile matter in the binder, and leaving the absorbed base or unvolatilizable portion of the binder in the briquets to form a per manent adhesion between the coke particles whereby a briquet substantially uniformly coked throughout is produced and crumbling and Waste prevented ROBERT A. CARTER, JR.
