APPARATUS FOR THE MANUFACTURE OF HYDRGCARBON GAS.

SPECIFICATION forming part of Letters Patent No. 296,201, dated April 1, 1884. Application filed December 21, 1883. (No model.)

To (155 whom it may concern I Be it known that I, \VILLrAu F. O. M. Mo- GARTY, a citizen of the United States of Amer-' ica, at present residing at St. Petersburg, Russia, have invented a new and useful Apparatus for the Manufacture of Hydrocarbon Gas, of which the following is a specification.

The object of my invention is to provide an apparatus by which an illuminating-gas pure and free from oxygen and carbonicoxide gas may be obtained.

My invention consists in the devices and apparatus hereinafter described and claimed.

In the drawings, Figure 1 is a view partlyin section and partly in elevation. Fig. 2 is a sectional elevation of the apparatus shown in Fig. 1. Fig. 3 is central sectional view through the furnace B and combustion-flue B of Fig. 1, and Fig. 4 is a detailed sectional view of the injecting device, by means of which the hydrogeugas and liquid hydrocarbon are introduced to the miXing-chamberI of Fig. 1. r

The same letters of reference refer to similar parts wherever used.

B, D, and E, are furnaces containing muffies G, F, and G. The construction of these three furnaces is similar, and may be understood by reference to Fig. 3, in which B represents the masonry of the furnace; C, a muffle of boileriron, which is provided with shelves abs, and with induction and eduction pipes d and c.

f is the grate-bar, and B the combustionflue. The combustion-fines ET, 1), and O are respectively provided with dampers B DI! Eh.

A is a steam boiler or superheater of any suitable construction, provided with an eduction-pipe, (Z, opening int-o the muffle G.

c is a pipe leading from the top of the muffle O to the bottom of the muffle F, and k is a pipe leading from the top of the muiiie F to the bottom of the muftle G.

Z is a pipe leading from the top of the muflie G and openinginto amiXing-chamber, I. The pipe 2 at its discharge end an is enlarged, and within this enlargement is introduced the discharge end of the pipe at, which leads from the hydrocarbon-holder H, the construction 50 being such that the passage of the hydrogen gas through the pipeland around the discharge end of the pipe it causes the ejection of the fluid hydrocarbon supplied from the tank or vessel H into the mixing-chamber Iin a spray or finely-divided condition.

K is a coil leading from the mixing-chamber H upwardly through a stack or due of masonry, and thence by a pipe, K, downwardly into a second flue or stack having as a continuation of said pipe K" a second coil, K. The latter coil, by means of the pipe K, is caused to discharge into the bottom of a washer, L, set in proper brick-work, and provided with a grate or firebox, M. The washer L is provided with two circulating-pipes, N and N, the. lower open extremities of each of which reach nearly but notquite to the bottom of said vessel, the upper extremities being bent over and provided with rose ends or openings.

M and M" are perforated diaphragms or, sieves.

O is a gas-discharge opening, and Q is an opening for the discharge of the products of combustion from the fire-box M.

l? P are pipes extending into the washer L, and having their open ends therein nearly but not quite in contact with the lower interior end of said chamber, the outer ends of said pipes being provided with suitable valves for closing the same; The shelves a- I) c are provided with calcium protoxide, (lime,) and the muffle F is upon its shelves provided with iron, copper, or other easily-oxidizable metal in a finely-divided condition, while the muflie G is upon its shelves provided with beds of charcoal. The materials are fed to said mnffles by removing the plates from the front ends thereof, and the luting by which they are held in place, after which the plates are replaced and luted in position. The muflies O and F, with their contents, are heated by means of fire upon the grate-bars f and g in the combustion-chambers B and D, respectively. I may here remark that the muflie of the furnace B may be charged with finely-divided iron or copper, and the muffle in the furnace D with lime, without changing the nature of my invention. Steam is fed from the superheater or boiler A, through the pipe d, to the I00 bottom of the muffle O, and passes backward and forward over and through the lime contained upon the shelves of said muffle, whereby oxygen and such carbonic acid as may be present in said steam are to alarge extent absorbed and removed therefrom. The hydrogen resulting, with such impurities as it may contain, is then conveyed by the pipe 6 to the bottom of the muffie F,where it is discharged, and passes over and through the heatedfinelydivided iron or copper or equivalent material contained upon the shelves thereof, by which said gas is further purified from oxygen and carbonic-oxide gas. This purified gas is then, by means of the pipe is, conveyed to the lower part of the muffle G, at which point it is' discharged in said muffle and passes over and through the bed of charcoal contained upon the shelves thereof, whereby its complete purification from oxygen and carbonic-oxide gas is insured. The'purified and highly-heated hydrogen so obtained is then conveyed by the pipe Z to the mixing-chamber I, and in its escape through the enlarged orifice m of the pipe Z into said chamber causes the stream of liquid hydrocarbon fed by the pipen from the holder H to be forced into said mixing-chamber I in a finely divided condition or spray. This mixture of hydrocarbon and hydrogen gases then passes through the coil K,which has been highly heated by fire upon the grate-bars J, whereby said gases become more or less fixed. From the coil K, through the pipe K, this gas may be conveyed to a second coil, K, heated by fire from the grate J, whereby a perfect fixing of the gas may be insured. The fixed gas so obtained is then conveyed through the pipe K to the washer L, and discharged into said chamber at the bottom thereof, said chamber having previously been supplied with hydrate of lime, ammonia, and water, or other suitable cleansing solution, the passage through which of said gas purifies the same andfits it for use, the purified gas being removed from said washer to a suitable storagereservoir through the orifice O. The hydrocarbon gas introduced to the purifier L through the pipe K is caused to come into more thorough con tact with the cleansing solution in said chamber by reason of the fact that the heat arising from the fire-box M causes a circulation of the bath in the washer L upwardly through the pipes N N, and a discharge of said mixture through the rose discharges on the upper ends of said pipes, respectively, and a consequent trickling of said solution downwardly through the perforated diaphragms M and M, by which the upward current of gas comes intimately into contact with said purifying mixture. The pipes P and I? may be used to free the purifier L of its contents, pressure applied to one of these pipes causing the contents of said purifier to be ejected through the other.

B and D are flues connecting the combustion-chambers of the furnaces B and D and D and E, respectively, said fiues being provided with dampers. This construction enables the retort of the combustion chamber E to be heated by causing the currents of heat and the products of combustion from the furnaces B and D to pass through the furnace E and be discharged through the smoke-stack E, whereby the charcoal of the muffle G may by heat be purified of its oxygen and carbonic oxide, when such purification beomes necessary, instead of removing said charcoal from said muffie, and replacing it by fresh supplies thereof.

Having thus described my invention, I claim 1. In an apparatus for the manufacture of hydrocarbon gas, in combination, three or more furnaces, the combustion chamber of each being provided with a closed muffle containing, respectively, lime; iron, (or copper in afinely-divided state,) and charcoal, a mixing-chamber provided with a hydrocarbon-injector, and a heating or fixing coil or chamber, the arrangement being such that superheated steam introduced to the first-named muffle may pass over or through the heated lime therein, and thence over or through the heated iron or copper in the second muffle, and thence over or through the charcoal in the third muffle, and thence into the mixing-chamber and become mixed with the hydrocarbon therein, and thence into or through the heating or fixing coil or chamber, as specified.

2. In an apparatus for the manufacture of hydrocarbon gas, in combination, a steam boiler or superheater, A, furnaces B, D, and E, provided, respectively, with muffles C, F, and G, said superheater and mufiles being connected by pipes 01, e,- and 7c, respectively, a mixing-chamber, I, provided with a hydrocarbon-supply tube, at, and with a hydrogengas-supply tube, Z, leading from the muffle G, and a fixing chamber or coil, K, as specified.

3. In an apparatus for the manufacture of hydrocarbon gas, in combination, a steam boiler or superheater, A, furnaces B, D, and E, provided, respectively, with muffies G, F, and G, said superheater and mufiles being connected by pipes d, e, and k, respectively, a mixing-chamber, I, provided with a hydrocarbon-supply tube, a, and with a hydrogengas-supply tube, 1, leading from the muffle G, one or more fixing chambers or coils, K, and a washer, L, as specified.

In testimony whereof Ihave hereunto signed my name this 11th day of December, A. D. 1883.
