(GRANTED UHDEB. THE PROVISIONS 01? THE ACT OF IABGH 3, 1921, 41 STAT. 1., 1315.)

To all whom it may concern:

Be it known that I, Liionon citizen of the Republicof France, and a resident of Paris, France, have invented certain new and useful Improvements in Oil-Gas Apparatus (for which I have filed applications in France on February 20, 1918, Patent No. 496,539, granted on August 6, 1919, and in England on October 15, 1918, Patent No. 140,128, dated March 25,

1920), of which the following is a speci-.

fication. 1

The present invention relates .to the production of rich gases and liquid fuel by means of petroleum residues and other hydrocarbon products of low thermal value.

It is known that the use of blue water gas or other gas of low thermal and lighting value is becoming more and more general for heating or lightinga its heatin and lighting pro erties becoming increase I by carbureting t e gas with hydrocarbon products of low value, such as by-products of petroleum, which are vaporized, in such 1 a manner that their almost complete, de-

com osition is effected and their transformation into hydro en and carbon. This method, however, oes not obtain the desired pur ose. I

a The ob]ect of the present invention is'to increase the calorific and lighting value of .blue water gas or other gas of low thermal value; and according to the invention, the

vapors of petroleum residues are passed through retorts containing catalyzers heated -tobetween 500 and 600 0. The heavy hydrocarbons split up into vapors and gases consisting of non-condensible 'olefines and hgdro'carbons which distil-- paraffius, light over up to"150 bons. The gases thus formed are andheavier hydrocarmixed with the blue water gas or'the like, whereas the liquid hydrocarbons which distil up to 150? C. may be used as fuel for explosion motors, Finally, a very small amount of carbon is deposited on the catalyzers.

.The catalyzers used may be metals such "as, copper or iron, in the form offilings or' "powder, which are formed into briquettes by means of a binder (gum, glue, starch, and. .rthe like),

1 r In the accompanying drawing, Figure 1 -represents a diagrammatic vertical sectional BLANCHET, a

' catal view of a unitary retort embodying the invention, andFig. 2 is a fragmented horizontal section taken through the catalyzing compartment of the retort.

As shown in said drawing, the retort of the present invention comprises a lower catalyzing portion or compartment A, in the mtoncn BLANCHET, or PARIS, FRANCE, nssxcnonmo LA soom'rn ms cumin ETA form 'of a pa'rallelepiped,'-and an upper vaporizing portion or compartment B; the two. portions A and B being'made of a single iron casting which is heated by a furnace or other means (not shown). In the interior of the compartment A are arranged channel-iron supports C carrying rows of briquettes D prepared as described abovep- These briquettesare placed side by side and fill the entire length of the channel-iron supports and the available height of the compartment A. The vaporizer B communis cates by means of a pipe connection E with a tank F containing the petroleum residues to be catalyzed, said pipe opening at its inlet end through the bottom wall of tank F and at its outlet end through one of the side walls of the vaporizer at H.

The petroleum residues contained in tank F and fed through ipe E are va orized in the vaporizer B, wgnch is heated y reason of its direct connection to the catalyzing compartment A whereon it is mounted, both compartments fol-min parts of the retort, as already stated. he vapors enter the zin compartment A through an opening an flow. through the catalytic mass formed by the briquettes ,D, contact with which decomposes them into amixture of light hydrocarbon vapors and gas. This mixture is discharged from the catalyzing.

compartment A through a pipe G which opens into a suitable condensing coil J, the

latter discharging, inturn, into a tank K;. .The liquid condensates discharged from coil J collect in tank K and the gas, which i also passes from said coil into the tank,

escapes therefrom through the outlet pipe L, whence it is sent into gas generators in order to be mixed-with blue' water gas or other gas of low thermal value. The light,

hydrocarbons obtained" by this process as previouslydescribed are likewise recovered.---

The arrangement described above has the advantage of enabl' the catalytic mass to be easily introduce 'into and withdrawn fi orn. the catalyzing chamber or compartqf merit A for removing the deposited carbonl. p

For this purpose it is sufficient to open the outerdoor A of said compartment and to withdraw in' succession the several channeliron" supports C with all the briquettes I thereom. The catalytic masscan then Joev easily regenerated.
