Description

IMPERIAL

PATENT OFFICE.

The present invention relates to innovations in the production of water gas.

Up to now it has been customary to use a liquid hydrocarbon and steam for this purpose Splash lime. The action of the lime on the injected substances produced the steam and the hydrocarbon is transformed into a mixture of hydrogen and carbonic acid. Around To prepare coal gas, this carbonic acid was then absorbed.

According to the present invention, the carbonic acid, instead of being absorbed, turns into colloidal oxide transformed. This mixture of hydrogen and carbon monoxide can be used afterwards, if this is desired to be carburized.

The present invention will become apparent from the accompanying drawings, in which the same Letters denote the same parts, easy to understand.

Fig. 1 is a partial representation of the apparatus in section, Fig. 2 is a plan view of the same.

A denotes a gas generating chamber which contains lime and B is the chamber in which the carbon oxide is generated and which best contains anthracite coal.

The chamber A is provided with the steam inflow pipe L and the naphtha inflow pipe K. The chambers A and B are connected by two tubes D and E , as shown; tube E is used when gas is produced, and tube D when the parts are heated.

M is a pipe which leads into the template C and through which the gas goes to the container or other apparatus.

The steam pipe H and the naphtha pipe J open into the lower part of the chamber B, as shown.

The tubes are fitted with suitable valves, which every gas engineer can handle is common and which should not be described further here.

The device works as follows:

After the chambers have been appropriately filled, air and naphtha are allowed to enter through the tubes JH at the bottom of chamber B and, if desired, a small amount of steam can also enter.

After the naphtha in chamber B has been ignited and the valve of tube E. is closed, while that of tube D is opened, the burning naphtha heats the anthracite in chamber B and the products of combustion pass through chamber A downwards and from there through the tube E into the Äusflufsrohr F, whose valve is then opened. After the coal and lime have been thoroughly heated, the valves in tubes G and H are closed, as are the valves in tubes D and F. After the valve in tube E has been opened, steam and naphtha are passed through tubes Z. and K is injected and, on contact with the lime in chamber A, is converted into hydrogen and carbonic acid. From there , going through pipe E , they go downwards through the hot anthracite into chamber B, where the carbonic acid is converted into carbon dioxide and the mixture escapes through pipe M and receiver C into the container or another

adequate apparatus. A further quantity of air can be driven through the pipe P into the chamber A in order to achieve the complete combustion of the products which pass through the pipe D when the apparatus is heated.

Claims (1)

Patent Claims: i. The process of producing hydrogen and carbon dioxide, consisting in passing a jet of liquid hydrocarbon and vapor through a heated lime containing chamber A and then a heated anthracite or similar body containing chamber B , the latter of which is that of the first chamber generated carbonic acid is converted into carbon dioxide. In connection with the patent claim ι. The method characterized by the process for reheating the lime and coal consists in that, when the lime and coal have cooled down to such an extent that their use in this state is undesirable, a stream of naphtha and air enter through the pipes JH and burn in chamber B and let the products of combustion pass through the other chamber A in order to reheat the coal and lime. For this purpose ι sheet of drawings.
