UNITED STATES PATENT orrlce GARLAND H. DAVIS, 01 BATON iBO-UGE, LOUISIANA, ASSIGNOB TO STANDARD OIL DEVELOPMENT COMPANY, A? CORPORATION OF DELAWARE LUBRIOATILTG OIL AND METEOD.OF MAKING- THE Application filed Kay 17 The present invention relates to imprdvements in hydrocarbon oils, and more specifically comprises a new product and its method of manufacture. My invention will be fully understood from the following description.
Heavy oils from wax bearing crudes con tain both wax and petrolatum, which cause materials had a tendency to reduce the pour,
the oil to set or solidify at a relatively high.
temperature. In the language of petroleum technology, these oils are said to have high pour points.
It has been previously recognized that an addition of an asphalt or tarry pointof lubricating oils, but the color of the oil was ruined at the sametime and the Conradson carbon value was unduly raised. ,I have discovered that the addition of relatively small quantities of certain other substances will greatly reduoe the pour point without detriment to the color of the oil or its other prope'rties.- J L Y I have found that the addition of small". quantities of certain oil-soluble, high molecular weight substances of a colloidal nature derived from petroleum are particularly advantageous in reducing pour points of lubricating oils since the colorof the oil is not seriously damaged. The quantity varies somewhat with the particular agent added, but is only a few'per cent; generally about 1% is sufficient for most purposes.
The material which I prefer to use is waxtailings or oxidized waxtailings, The former is a product obtained as the final distillate during the coking distillation, and the latter is formed by exposing the waxtailings to air at an elevated temperature solve in the oil, and may be either liquefied 1929. Serial No. 304,004.
added to the oil. The solvent may then be 1 evaporated, but in many cases it is so small in amount as to have no deleterious efi'ect. Whether the substance is actually in true solution in the oil is unknown to me, and it may be that it is colloidally dispersed, but in any event it produces a marked lowering of the pour point without other disadvantages, at a relatively low cost, and appears to be in a stable form. v
As an example of the use of my process, an oil derived from a wax-bearing crude has a color of 1 Robinson and a pour of 45 F. To
this oil 1% of oxidized waxtailings is added A and dispersed homogeneously through it by agitation and heating. The'oil is then allowed to cool and is found to have a color of A Robinson and a pour of 10 F.
My invention is not to be limitedby any 1.-"A composition of matter comprisin. a
