I MOTOR-FUEL.

n 1 2g7 388 Specification of Letters Patent.

No Drawing. 7

To all whom. it may concern:

Be it known that I, CURT L. E. MUELLER,

a citizen of the United States, and a resident i the distillate derived from crude petroleum.

of Joliet, in the county of \Vill and State of Illinois, have invented certain new and useful Improvements in Motor-Fuel, of which the following is a specification.

My present invention relates to the provision of a, fuel suitable for use in internal combustion engines and the objects of my invention are the provision of such a fuel which can be made, at least in part, from substances not heretofore employed in the manufacture of such a fuel, which can be economically made, which will be fully combustible, and which will have, upon combustion, an improved power producin value. The fuel hereinafter described retains sufficient lubricating qualities so as to lubricate the cylinders of an internal combustion, en-

gine which materially reduces the amount of lubricant necessary in the running of such an engine and will absolutely prevent the cylinders ever running dry and sticking or freezing, as it is called.

In order to attain the above results, I have had recourse to the so-called coal tar derivatives which are the by-products of the In this grouping I have disregarded the ammoniacal fumes which are driven off in the distillation of the coal tar derivatives at the comparatively low temperature of 20 degrees centigrade. The first group of which I avail myself are what may be styled the light oils or crude naphtha, which distil from the coal tar derivatives up to a temperature of '170 degrees centigrade. These oils generally have the characteristic of a specific gravity of less than one and in the preparation of the light oils for use iii my fuel and after they have been extracted by distillation of coal tar derivatives up to a temperature of 170 degrees centigrade, the light oils which I use are prepared by washing them through a solution of sodium nitrite (N aNO Baum. This is done prior to the mixing of the light oils with A second group of coal tar derivatives are called the dead oils; and a third group Patented Mar. 18, 1919.

Application filed October 21, 1918. Serial No. 259,056.

are the heavy oils or anthracene oils. Both the dead oils and the anthracene oils usually are characterized by specific gravity in excess of one, or that of water, and distil over from the coal tar derivatives at a temperature in excess of 180 degrees Centigrade.

I do not employ the dead oils, with the exception of naphthalene, diphenyl, and phenol, in the manufacture of my fuel and these unused dead oils, may be separated from the heavy oils, or anthracene oils by treatment with caustic soda or in any other desired manner. After the extraction of the dead oils and the heavy oils from the coal tar derivatives, there remains a. fifth class generally but definitely described as pitch and subsides, but of this class I make no use.

Among the anthracene oils above referred to are anthracene (C H chrysene (C, H pyrene (C H fluorene (C H ;and retene(C H, Of the dead oils I employ naphthalene (C H diphe nyl (C I-I and phenol (C H OH); and I also employ anthraquinone (C H O which is the product of the oxidation of anthracene with 'chromic acid.

The above, as well as other anthracene and in the following manner:

Seventy-five parts of naphthalene are dissolved at, preferably 100 degrees centigrade,

in 100 parts of light oils or toluene; fifty parts of diphenyl are dissolved at the same temperature in 100 parts of light oils or toluene; twelve parts of anthracene are dissolved at 100 degrees centigrade in 100 parts I of light oils or toluene; five parts of chrysene are dissolved at the same temperature in 100 parts of light oils or toluene; forty parts of pyrene aredissolved at 100 degrees centigrade in 100 parts of light oils or toluene; two and fifty hundredths parts of anthraquinone are dissolved at 100 degrees centigrade in 100 parts of light oils or toluene; thirty parts of fluorene are dissolved at 100 degrees Centigrade in 100 parts of light oils or toluene; fifteen parts of retene are dissolved at 100 degrees centigrade in 100 parts of light oils or toluene.

After dissolving the naphthalene, pyrene and flfiorene in light oils or toluene, these radicals may be treat-edto produce neutral picrates and then dissolved in the propor=v tions and in the manner above described for the other radicals. A mixturev of the above solutions is then made with the product of distillation of crude petroleum when heated to a temperature up andto 350 degrees centigrade. The comparativel .low specific gravities of the solutions a ove described renderit possible to control, within desired limits, the Specific gravity of the final composition by taking a greater or less propor tion of the aforesaid solutions. The desired flash point also can likewise be controlled in the same manner, as a greater proportion of the solutions will'lower the flash. point.

I have not set forth herein the propor';

' tions for mixing as different specific gravities and difierent flash-points are'required in different localities and the requisite specific gravity and flash "point'caneasily be ascertained upon mixture by means of a hydrometer, with a'Baum scale, and inconnection with flash tests.

- It is believed that the fuel oil, compounded as above described, is freely-"and fully.

combustible, leaving practically "no carbon deposits and producing a satisfactory power, greatly in excess of that of the entire petroleum fuels, now generally employed, and will lubricate the engine cylinders.

l/Vhile I have described a preferred manner of carrying out my invention, I do not desire to be limited to the specific disclosure made herein, for it will be obvious to others skilled in the art' 7 that modifications and refinements thereof. may be .made without materially departing from the teaching and permit.

disclosure herein made, it being my intention to claim my invention as fully and comhave been pic/rated with the products of the distillation of crude petroleum. at a temperature up and to 350 degrees centigrade.

A fuel oil comprising a mixture of solutions of naphthalene, diphenyl, anthracene, chrysene', pyrene, anthraquinone,fluorene and retene in the light oils derived from the fractional distillation of coal tar with the products of the distillation of crude petroleum at a temperature up and to 350 dey grees centigrade.
