METHOD OF TREATING AND UTILIZING PETROLEUM RESIDUES.

To all whom it may concern:

Be it known that I, VAGLAV Kfn'DLo, a subject of the Emperor of Austria-Hungary, reslding in Prague, Bohemia, in the Empire of Austria-Hungary, engineer, have invented certain new and useful Improvements in Methods of Treating and Utilizing Petroleum Residues, of which the following is a specification.

The residues remaining in petroleum refiners as Waste and known under the term of goudron (pitch) have hitherto only been utilized to a very limited extent and under considerable difiiculties. Now according to an improved method such residues are utilized and may be employed partly for combustion under favorable circumstances and partly for obtaining pure carbon for various chemical-technological purposes.

An apparatus for carrying out my process 1s shown as an example in the accompanying drawings, in which- Figure 1 is a longitudinal section; and Fig. 2 a front View of a suitably arranged furnace installation.

In the fire chamber there is a grate Rwith a tilting grate K of known construction. On these grates an ordinary coal fire is maintained at least at first, while through the door T the viscous residues are conveyed onto a lattice-work or grate G. These residues are almost or entirely freed from' hydrocarbons by the radiating heat of the coal fire, while they are in the process of combustion and drop through between the bars of the lattice or grate G, forming stalactites. The latter still burn during their formation and adhere tothe lattice until, in consequence of their own weight, or of externally acting influence by the shaking of the grate or lattice G, they drop onto a plate,

' P. The latter is also heated by the radiating heat of the coal fire on the grate R, and is provided with perforations in order that the descending already partially carbonized pieces may receive a sufficiency of air. On this plate P the residues which have dropped down are entirely coked and the heat which is thereby developed assists the further de? scent of the residues still lying on the lattice or grate G. The gases which are formed by the combustion of the residues are conveyed into the existing heating fines, while a depending baflie M prevents the direct escape of the volatile products of combustion into the heating flues.

Specification of Letters Patent. Patented Aug. 24;, 1909. Application filed. December 13, 1906.

Serial No. 347,632.

The pure coke accumulating on the plate P is either pushed down as combustible material onto the grate R, in which case a smaller addition of other fuel on the grate R then sutfices in order to permanently maintain the combustion in the desired manner, or the coke is removed from the heating apparatus through a door 6 located above the plate P. The coke thus employed may be employed for other industrial or chemical purposes. Now if it be merely a question of burning the, mass of pitch, the intermediate grate may under certain circumstances be entirely omitted, so that the material from which the gas has been removed may fall directly onto the furnace hearth. Eventually after the operation of combustion has been once initiated, an addition of other fuel may even be found unnecessary, so that it is only necessary to make a temporary fire of other fuel on the grate R K.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. The improvement in treating and utilizing petroleum residues, which consists in placing the residues on a perforated tray in a furnace, melting the residues by heat from the furnace, catching the melted residues as they fall from the tray by a second tray also heated from the furnace, and converting the residues in the melted condition into carbon.

2. The method of treating and utilizing petroleum residues, which consists in freeing the same from gas and melting them under partial combustion on a wide meshed lattice by the heat of a separate furnace, catching the melted residue on a further lattice or grate, and coking or carbonizing the same thereon.

3. The method of treating and utilizing petroleum residues, which consists in freeing the same from gas and melting them under partial combustion on a wide meshed lattice by the heat of a separate furnace, catching the melted residue on a further lattice or grate, coking or carbonizing the same thereon, and consuming the resulting carbon in the furnace.

In witness whereof, I have hereunto signed my name this 29 day of October 1906, in the presence of two subscribing witnesses.

VACLAV KRIDLO.
