Under the microscope it l 2f: has been found that the gas, such as air, due to the agitation, will disperse and form globules or bubbles, each one of which will be coated with a. film of water contained within a skin of oil, and it has been found that a compound of this nature will remain in the foamy condition indenitely. Actually, such a compound has remained In stable condition for a period of more than a year without any noticeable stratification.

The amounts of air and water used in the compump 26 is arranged at one side of the casing I5, as shown in Fig. 3, and at the opposite side of she casing,'the oil pump 28 is-located, as shown .n Fig. 4. The intake 29 of this pump is coniected to any suitable oil supply, while the out- .et pipe 30 of the pump leads to the inlet 20 of ;he casing.

The invention permits the production of a fuel from low grade and low specific gravity hydrocarbons, such as heavy crude petroleum, oil field emulsions, still bottoms and the like, which are ordinarily unsuited for use in fuels or refining. The invention also allows of the production of a compound from the same loW grade starting stocks, which may be economically used for the production of illuminating and heating gas, and for the production -of refined petroleum products. a For the purpose of producing a fuel, by way of repetition, it may be stated briefly that heavy crude petroleum, still bottoms or like hydrocarbons, and water, areY pumpedjnto a mixer andV thoroughly agitated in the presence of air or any other suitable gas under super-atmospheric. pressure, the pressure required depending upon the nature of the hydrocarbons undergoing treatment. Likewise, the amount of water that may be put into the mixture depends upon the character of the hydrocarbons. With particularly heavy" hydrocarbons, it will be necessary to preheat the same to, increase its iiuidity to permit it to be properly handled by the pumps.

Upon proper agitation for a suilicientY length of time, the compound is formed, and it is substantially permanent in character, and does not tend to separate. Microscopic examination indicates that the compound is composed of minute globules of lair or other gas, surrounded by films of water and oil, in the order named.

'I'he compound ythus produced may be stored or, if desired, may be consumed as produced.

If refined petroleum products are desired, as the end products, the initial procedure, so far as the production of the compound is concerned, is the same as when the compound is to be produced for fuel purposes, that is, a. compound composed of hydrocarbons, water and gas is made, and to the same is added other elements that may be desired in the end products, for example, benzole.

On the other hand, as before stated, if itis desired to produce gas, then some gas such as natural gas, water gas or blue gas, is substituted for the heated air in the mixer, so that the compound includes such gas instead of air.

By heavy liquid hydrocarbons. in the followingclaims, I means low grade and low specic gravity hydrocarbons, such as heavy crude petroleum, oil eld emulsions, still bottoms and the like. I have found that such heavy liquid hydro- 'carbons have sumcient strength and tenacity to maintain the globule condition over extended periods of time. f

While I have disclosed the principle of my invention, as well as my method in such manner that they may be readily understood by those skilled in the art, I am aware that changesmay be made in the details disclosed, without departing from the spirit of the Iinvention, as expressed in the claims.

What I claim and desire to secre by Letters Patent is: i

1. A process of producing a substantially per- I manent emulsifled compound comprising mixing and thoroughly beating an aqueous liquid, a heavy hydrocarbon liquid and a gas under superatmospheric pressure, and continuing the beating for a suicient length of time to form arremulsified compound substantially permanent in character and one in which the components do not tend to separate.

2. A process of producing a substantially permanent emulsied compound composed of a combustible mixture of water, heavy liquid hydrocarbons and a gas, consisting in vigorously beating the water and hydrocarbons ln the presence or the gas while under super-atmospheric pressure for a sufficient length of time to form an emulsified compound which is substantially permanent in character and which does not tend to stratify.

3. A substantially permanent emulsifed compound consisting of heavy liquid hydrocarbons, aqueous liquid and a gas, the gas being in minute globules surrounded by lms of the aqueous liquid and the heavy liquid hydrocarbons in the order named.

4. A substantially permanent emulsied compound comprising a multiplicity of minute gas globules surrounded by iilms of water and heavy hydrocarbon oil in the order named.

5. A substantially permanent emulsified compound comprising a multiplicity of minute gas globules surrounded by lms of water and heavy hydrocarbon oil in the order named, said emulsied compound being formed by a continuous beating operation under super-atmospheric pressure.
