Patented June-21, 1938 UNITED STATES PATENT OFFICE 2.121.431 rnocrss or MAKING ASPHALT No Drawing. Application February 12, 1937, Serial No. 125,428
9 Claims. (Cl. iec -w This invention relates to the manufacture of asphalt; and it is among the objects of the invention to provide a process making possible faster operation than that customary in asphaltmaking, and capable of giving superior products. Other objects and advantages will appear as the description proceeds.
To the accomplishment of the foregoing and related ends, the invention, then, comprises the m, features hereinafter fully described, and particularly pointed out in the claims, the following description setting forth in detail certain illustrative embodiments of the invention, these being indicative however, of but a few of the various 15 ways in which the principle of the invention may be employed.
The raw material may be the stocks customary, in general a petroleum residuum or the residue left after the vaporizable hydrocarbons through 20 the range of lubricating fractions have been taken oil. The raw material, in accordance with the invention, is subjected to the action of heat and oxidizing conditions, and while oxygen gas may be used. in practice air is generally more 5 desirable, and such gaseous agent may be introduced into the residuum to accomplish both the oxidation and agitation, as by air-blowing, while at the same time carrying a particular catalyst.
In accordance with the invention, the latter is at! an inorganic gasiform agent, or at least'capable of being carried along by an air stream, and containing an acid-forming element such as sulphur ora halogen, and selected from the group consisting of Selene-sulphide, SeS, thlonyl perchloride, SOClz, sulphuric oxyfluoride, $021 2,
ghosphorus oxychloride, POCla, phosphorus oxyuoride, POFa, phosphorus thiofluoride, PSFz, and sillco-fluoroform, SiHFa. Particularly desirable are the halogen-containing compounds, 40 and especially the phosphorus-halogen compounds.
These catalysts are notably effective, and are employed in small amount, as for instance .0001-1 per cent, and where an air stream is employed 45 as the primary reagent, the catalyst may be proportionally fed along therewith. The temperature of treatment is in general 400 to 550 B.
As a further refinement, particularly advantageous in some instances, the residuum may be 50 air-blown or oxidized by heating at 400-550" F.
with oxygen or air alone without the catalyst to partial conversion to desired specifications, and
then the catalyst is fed in with the air and the reaction is completed to the final desired specifications of melting point, pepetration, etc.
As an example: 1000 barrels of petroleum residuum, obtained by vacuum reduction of Mid-Continent crude, and having a penetration of 200 at 77 F., is charged into a tank-which may be suitably equipped with an air spray in the bottom. Air is blown in at the rate of about 50,000 cubic feet per hour. The temperature of the material rises during the oxidation to about 500 and the treatment is carried on until the penetration of the material is about 100 at 77 F. 10 At this point, phosphorus oxychloride is admitted along with the air in amount of 0.5 per cent by volume, until the material reaches a penetration of about 50 at 77 F. The air and catalyst is then stopped, and the material is pumped to storage or shipping containers.
As another example: Petroleum residuum similarly is agitated and blown with air containing about 0.5 per cent by volume of phosphorus oxychloride, the temperature being maintained at around 500 F., and the treatment continued until-the material reaches a penetration of about 50 at 77 F. The time of treatment may be around eight hours.
As another example: Petroleum residuum is similarly agitated and blown with air carrying phosphorus oxyflouride as catalyst,- until the product samples to the desired penetration.
As another example: Residuum similarly is agitated and air blown, with supply oi sulphur oxyfiuoride as catalyst.
As another example: Residuum similarly is agitated and blown with air carrying phosphorus thiofluoride as catalyst.
As another example: Residuum similarly is agitated and blown with air carrying selenosulphide as catalyst.
As another example: Instead of starting with the catalyst .as in the immediately preceding examples, the residuum is first air blown without a catalyst, until the penetration is about 100 at 77 F. Then either of the catalysts noted is introduced with the air, and the treatment continued until the product shows a penetration of about at 77 F. 5
As another example: Residuum is oxidized with air blowing, until the material shows a penetration of at 77 F., then the gaseous catalyst, carried by air, is mixed with the asphalt for a period of about half an hour, the temperature 50 being maintained at around 500 F.
Other types of blowing equipment, aside from the tank mentioned. may be employed, those such 7 as in my Patents Nos. 1,982,920, 1,950,900 and 2,002,670 being especially advantageous. 5a
Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the features stated in any of the following claims, or the equivalent or such, be employed.
