CORPORATION 0] CALIFORNIA DECOLORIZING MATERIAL AND METHOD OF PRODUCING SAME Application filed Kay 22, 1926. Serial no. 110,980.
My invention relates to a decolorizing material which is particularly adapted for the decolorizing of gasoline and the like, and also relates to a process of manufacturing such a decolorizing material.
Gasoline is decolorized and purified before it is placed on the market in order to remove certain of the unsaturated and aromatic hydrocarbons, together with any other impurities of which the gasoline should be rid.
It is an object of this invention to provide a novel and improved process of treating gasoline whereby it is more guickly and more thoroughly decolorized an refined.
I have discovered a decolorizing material which is rapid and thorough in decolorizing gasoline and other substances which have practically no water content.
It is accordingly one of the objects of this invention to provlde a decolorizing material for treating substances having no water content.
The decolorizing material of my invention consists of a cla having decolorizing pro erties and acid w ich are intimately m1xe together. I find that it is very important that the clay and the acid be substantially free from water.
It is a further object of my invention to provide a process of making the decolorizing material 0 my invention.
Other objects and the s ecial advantages thereof will be made mani est hereinafter.
In the drawing which illustrates an apparatus adapted for conducting the process of my invention by which the decolorizing clay of my invention is produced, 1- is a dehydrator in the form of a kiln, 2 is a primary pulver-- izer which may be of any standard form, 3 is a mixer, and 4 is a secondary pulverizer which may be of any standard form.
The decolorizing clay is supplied to a rotating cylinder 11 of the kiln 1 by means of a conduit 12. The cylinder 11 is rotatably supported by rollers 13 which engage tracks 14 thereof, and is rotated by means of a pinion gear 15 which engages a gear 16 of the cylinder 11. The. interior of the cylinder 11 may be. heated by a fire-box 18. The decolorizing clay is carried from the dehydrator 1 to the dehydrated decolorizing clay thereinto and.
for removing it therefrom.
The decolorizing clay is taken from the primary pulverizer 2 and delivered to the mixer 3 by means of a chute 30. The mixer 3 consists of a shell 31 which provides a mix ing chamber 32. Secured to a shaft 33 is a plurality of mixing paddles 34 which are situated in the mixing 0 amber 32. The shaft 33 is driven by means of bevel gears 36. Acid, which is preferably sulphuric acid, is delivered to the mixing chamber 32 by means of an acid pipe 37. Extending from the bottom of the shell 31 is a conduit 38 having a valve 39. The conduit 38 delivers a mixture from the mixer 3' to the secondary pulverizer 4. The secondary pulverizer 4 has a rotatable drum 41 which is supported by bearings 42 through which shafts 43 extend, and is driven by a pinion gear 44 which engages a large gear 45 of the drum 41'. A door 46 is pro- I vided'inthe drum 41 for introducing a mixture thereinto and for removing the mixture therefrom, which mixture when removed is deposited in a chute 49 by means of which it is carried from the secondary pulverizer 4.
The process of producing decolorizing material is substantially as follows:
The clay used in my invention possesses marked decolorizing properties but it is impossible at this time to accurately define its physical characteristics. The decolorizing clay, as I call it, is delivered by means of a conduit 12 to the left end of the cylinder 11 of the dehydrator 1. The cylinder 11 is heated to a temperature of 300 F. or above, and the decolorizing clay is not only thoroughly dried in the sense that it is free from water, but it is dried to such a degree that substantially all of the water of crystallization is driven therefrom. When the decolorizmg clay passes from the right end of the deh drator 1 into the chute 20 it is in a state of tli is removed therefrom. The dehydrated clay is then delivered to the primary 2 and is introduced into the interior of the drum 23 thereof, the door 28 being removed for this purpose. The door 28 is then replaced and the drum 23 is rotated.
In the drawing I have shown the primary pulverizer 2 and the secondary pulverizer 4 as being ordinaryv tubemill pulverizers but it should be understood that other types may be used. Also the dehydrator is shown in the 7 form of a. kiln but another type of dehydrator;
1 might be used in lieu thereof.
After the dehydrated decolorizing clay has been thoroughly pulverized, the door 28 is opened and it is delivered into the chute 30, by means of which it is conducted to the mixing chamber 32.
In the mixing chamber 32 the decolorizing clay is very intimately mixed with an acid which is substantially free from water, by the action of the mixing paddles 34 which are rotated with the shaft I prefer to use sulphuric acid in my,decol0rizing material but some other acid might be used if desired.
I find it desirable to mix from 4 to 8 per cent sulphuric acid by weight with the decolorizing clay. The sulphuric acid, since it is substantially free from water and since the decolorizing clay is substantially free from water, has practically no reaction upon the decolorizing clay. Therefore, a mechanical 35 mixture of free sulphuric acid and decolorizing clay is obtained.
After the decolorizing clay and sulphuric acid have been intimately mixed in the mixer 3, the valve 39 in the conduit 38 is opened and the mixture is delivered to the secondary pulverizer 4. The door 46 of the drum 41 is opened so that the mixture may be introduced thereinto, after which the door 46 is replaced and the drum 41 is set into motion. After the mixture is again thoroughly pulverized, it is ready for market andis taken from the secondary pulverizer 4 by means of the chute 49.
The decolorizing material produced by my invention is adapte for use in treating substances having no water content and is especially adapted for treating gasoline. In the treatment of gasoline by the decolorizing material of my invention, the gasoline to be treated is thoroughly mixed with an amount of decolorizing material in a mixer which is similar to the one shown in Fig. 3. It is very often desirable to heat the gasoline while it is being mixed with the decolorizing material. The decolorizing material effectively removes all of the impurities from the gasoline, these impurities being adsorbed thereby. After a thorough mixture has been effected, the decolorizing material is sepa- 65 rated from the gasoline, preferably by a orough dehydration and all of the water pulverizer clay to a temperature above 300 filtering process, leaving a gasoline product whirlxh is very highly refined and ready for mar (et.
One. of the important features of this invention resides in the decolorizing material and its method of production, which decolorizing material is substantially free from water. Because of this, no reaction will take place between the decolorizing clay and the sulphuric acid and therefore neither of these constituents will in any way be weakened by their intimate association. The decolorizing clay and the sulphuric acid are finely divided due to the pulverization thereof, and are brought into intimate contact with the gasoline, thereby effecting a more eflicient action and a more rapid treatment thereof.
I claim as my invention:
L A decolorizing material consisting of: decolorizing clay having no water content either in the form of free or divided water of crystallization; and sulphuric acid having no water content, said sulphuric acid being intimately mixed with said decolorizing clay.
2. A decolorizing material consisting of: decolorizing "clay having no water content either in the form of free or divided water of crystallization; and four to eight per cent by weight of sulphuric acid having no water content, said sulphuric acid being intimately mixed with said decolorizing clay.
3. A process of making decolorizing material comprising: dehydrating decolorizing clay so that all free water and water of crys-- tallization is removed; an intimately mixing sulphuric acid having no water content with said decolorizing clay. l
4. A process of making decolorizing. material comprising: dehydrating decolorizing clay so that all free water and Water of crystallization is removed; pulverizing said decolorizing clay; and'intimate'ly mixing sulphuric acid having no Water content with said decolorizing clay.
5. A process for making ad'ecolorizing ma- 1 terial comprising /heating adecolorizingclay to a dehydrating temperature so that all free water and water crystallization is removed; and intimately mixing from four to eight per cent of sulphuric acid having no 1 Water content therewith. v 6. A process for making a decolorizingmaterial comprising: heating a decolorizing F. so that all free water and water of crystallization 1 is removed; and intimately mixing from four to eight per cent of sulphuric acid having no water content therewith.
In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 1 17th day of May, 1926.
