TREATING one 7 Specification of Letters Patent. Application filed November 9, 1905. Serial No. 286,471.

Patented June 23, 1914.

To all whom it may concern:

Be it known that I, JESSE A. DUBBs, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or dis-' covered certain new and useful Improvements in Treating Oil, of which improvements the following is a specification.

The invention described herein relates to certain improvements in the distillation of hydro-carbons and has for its object the maintenance of the fluid at a temperature at which a breakin up of the hydro-carbon occurs and at which the hydrogen will combine with the oxygen, mainly or solely by the heat developed by such chemical change or combination. y

In the accompan ing drawings forming a part of this speci cation is shown in sectional elevation a form of apparatus adapted to the practice of my invention.

In the practice of my invention the hydrocarbon o1l z. e. petroleum or oils identified with petroleum is charged into a retort or vessel 1 having a suitable connection to a condenser 2. This liq uid hydro-carbon, if it contains any water, 1s first treated preferably by heat to drive off such water. The water may be removed as described in application No. 286,47 2, filed November 9th, 1905, or in any other suitable manner known in the art. After the water is driven off, the temperature of the hydro-carbon is increased,'provided the temperature required for driving otf the moisture is not suflicient, to start a generation of gases which by preference should be free. This generation of the hydro-carbon gases or vapors will be indicated by the flow of distillate from the condensing coil. The hydro-carbon can be heated to the required temperature to produce hydro-carbon vapor in any suitable manner as by the external application of heat to the containin vessel, by a steam coil in-the vessel or by orcing hot air through the hydro-carbon. The temperature employed may var from 100 F. to 600 F. de pendent upon t e character of the hydrocarbons treated. I have found that as soon as the hydro-carbon reaches a temperature at which a breakin up or decomposition in' the presence of air 1; ereof occurs, that a portion of the h drogen will combine with the oxygen of air forced through the hydrocarbon by perforated pipe 3 connected to a suitable pump. This combination of hydrogen and oxygen will reduce sufiioient heat, if sufiicient volumes 0 air beforced through the materialnot only to maintain-the hydrocarbon at an initial breaking-up temperature, but also to raise it to the temperature required for a further breaking-up. Hence after the dehydrogenation of the hydro-carbon which produces water by the combination of the oxygen'of the air and hydrogen from the hydro-carbon begins as will be evidenced by the appearance of water with the other distillate, no heat except that produced' by the combination of the oxy on of the air with the hydro en, etc., of the ydrocarbon is required an cold air'can be used for completing the distilling operation. It is found in' practice that as the breaking-up and evaporation proceeds, lar er volumes of air are required to obtain an maintain the desired rise in temperature for a complete evaporation of the hydro-carbon.

It is characteristic of my improvement that after the heating necessary to start the breaking-up of the hydro-carbon whereby the hydrogen is placed under conditions no further heat need be applied, the chemical combination of the oxygen and hydrogen supplying suflicient heat which will be proportional within certain limits to the amount of air sup lied to the hydro-carbon and which will e generated uniforml throughout the body of the material treate When it is desired to prevent a discoloration of the residuum or to bleach the latter as in the manufacture of lubricating oils, steam may be forced through the material while being treated with the air.

I claim herein as my invention:

1. As an improvement in the art of distilling hydro-carbons, the method herein described which consists in heating the material to a oint at which the hydro-carbons would be broken up if mingled with air, forcing air through the same and maintaining the heat by the chemicalreaction produced. v

2. The method of dehydrogenating hydrocarbons which consists of passing air through them when heated to a tem erature at which the oxygen of the air will unite with the hydrogen of the hydro-carbon, then continuing the operation bypassing through the hydro-carbon a suflicient'fquantity of air to cause by the chemical action a desired temperature for so continuing distillation.

3. The method of dehydrogenating hydrocarbons which consists of passing air through them when heated to a temperature at which the oxygen of the air will unite with the hydrogen of the hydro-carbon, then continuing the operation by passing through the hydro-carbon a suiiicient quantity of air to cause by the chemical action alone a desired temperature for so continuing distillation.

4. The method of dehydrogenating hydrocarbons vwhich consists of passing. air through them when heated to a temperature at'which the oxygen of the air will unite with the hydrogen of the hydro-carbon, then continuing the operation by passing through the hydro-carbon a sufficient quantity of air to cause by the chemical action a desired temperature and regulating the tem erature of distillation of the hydro-carbon y regulating the quantity of the air passed into it.

5. The method of distilling hydro-carbons which consists of passing air through them when heated to a temperature at which the oxygen of the air will unite with the hydrogen of the hydro-carbons, then continuing the oigeration by passing through the residue a'su cient quantity of air to maintain by chemical action a sufficient heat to carry on the distillation.

6. The method of distilling hydro-carbons without theuse of external heat which consists of passing air through the hydro-car bons while inclosedin astill and at a temperature at which the oxygen of the'air will unite with the hydrogen of the hydro-carto maintain this temperature and such' higher temperatures as may be necessary to complete the distillation, and then withdrawin the primary fire and completing the distil ation by the use of the internal heat produced by chemical action alone.

8. The method of treating hydrocarbons, which consists in passing air through them when initially heated to a temperature at which the oxygen of the air will react on the hydrocarbon, then continuing the operation by passing through the hydro-carbon a sufiicient quantity of air to cause by the chemical action alone the desired temperature for maintaining the necessary reaction, without the agency of any substantial external application of heat, and regulating the tempera ture required for the reactions by regulating the quantity of air passed into the hydrocarbons.

In testimony whereof, I have hereunto set my hand.

JESSEA. DUBBS.
