| 64 | Selection and blending of feeds for asphalt manufacture | US14576281 | 2014-12-19 | US10005907B2 | 2018-06-26 | Eric B. Sirota |
| Methods are provided for predicting the properties of an asphalt fraction that contains two or more asphalt components based on measurements of the viscosity versus temperature profile for the components of the asphalt fraction. The viscosity versus temperature profile for each component can be used to determine characteristic (such as limiting) values for the viscosity and temperature for a component. Based on this ability to determine characteristic values for an asphalt blend based on the properties of individual blend components, appropriate blends of asphalts can be selected in order to arrive at an asphalt blend with desired properties. | ||||||

| A bitumen having the properties of a Newtonian liquid is a mixture of a first oil pitch made of particles of soot and saturated oils and a second oil pitch made of aromatic oils and resins, characterized in that the first oil pitch has saturated oils at a content of at least 10% in wet weight and the second oil pitch has aromatic oils at a content of at least 10% in wet weight. | ||||||

| Methods are provided for forming an asphalt fraction corresponding to a blend of asphalts, the asphalt fraction having at least one property that is unexpectedly better than the expected property value based on the individual asphalts used in the blend. The unexpectedly beneficial blends of asphalts are formed in part by including an effective amount of a Napo crude oil or crude fraction in the feed used to form the asphalt fraction. For some asphalt blends, including an effective amount of a Napo crude in the feed can allow for production of an asphalt with a low temperature performance grade that is lower than the predicted value by at least 0.5° C., such as at least 0.75° C. or at least 1.0° C. | ||||||

| 70 | Low softening point petroleum pitch and sealer | US09442154 | 1999-11-16 | US06383365B1 | 2002-05-07 | D. Chris Boyer; Patricia K. Doolin |
| A 40 petroleum pitch is disclosed. A high melting point petroleum pitch is blended with a high boiling normally liquid petroleum derived hydrocarbon stream to form a mixture having a softening point of 35-45 C. as a partial or complete replacement for coal tar pitch used in driveway sealer and other sealer applications. Driveway sealer (an emulsion of clay, water and binder) made with A 40 has excellent durability and can have a greatly reduced amount of, or be essentially free of, coal tar pitch, greatly reducing the toxicity and odor of the sealer. | ||||||
| 71 | Sulfur-in-oil in asphalt and polymer composition and process | US464434 | 1999-12-16 | US6133351A | 2000-10-17 | Roger E. Hayner |
| A sulfur in oil in asphalt and polymer blend is disclosed. An asphalt and polymer blend is first prepared and then a slurry of solid sulfur in liquid oil added. Addition of a slurry of solid sulfur in oil or oil containing sulfur compounds, permits rapid and effective uniform dispersion of the sulfur component in the asphalt/polymer blend. Uneven mixing, which can occur when sulfur is separately added as a solid to the asphalt blend, is avoided. Polymer use is optimized because polymer matrix development (digestion/swelling) can be completed before cross-linking occurs. The method is safer because formation of explosive clouds of sulfur dust is avoided. | ||||||

| Described are preferred pitches which comprise a blend of coal tar pitch, petroleum pitch and gilsonite pitch, and preferred processes and compositions which can be used to form such pitches. The pitches have substantially reduced contents of polyaromatic hydrocarbons (PAH's) relative to standard coal tar pitches, and are thus more favorable from health, safety and environmental standpoints. | ||||||

| A process for the preparation of petroleum-derived binder pitch, comprising heat treating a mixture of both (1) a heavy fraction boiling at not lower than 200.degree. C. and being obtained by the steam cracking of petroleum such as naphtha and (2) a heavy fraction boiling at not lower than 200.degree. C. and being obtained by the catalytic cracking of petroleum such as gas oil. | ||||||
| 74 | Process for preparing binder pitches | US808175 | 1977-06-20 | US4176043A | 1979-11-27 | Johannes N. van Eijk |
| A process for preparing a binder pitch, in which a high-aromatic residual fraction from petroleum raw materials is mixed with a coal tar fraction in weight ratios of about 1:9 to 9:1 and heated, while during heating the mixture is kept in contact with a dehydrogenating agent, in particular an oxygen-containing gas. | ||||||
| 75 | Method of separating bitumin from bituminous sands and preparing organic acids | US455021 | 1974-03-26 | US3951778A | 1976-04-20 | John W. Willard, Sr. |
| Bituminous sands are intimately contacted with an aqueous medium containing a catalytically effective amount of a novel catalyst to separate the bitumin at temperatures below the decomposition point of valuable hydrocarbons contained therein. Usually the temperatures of separation are not higher than 100.degree.C and preferably are about 40.degree.-90.degree.C. The catalyst used in practicing the present invention may be prepared by steps including admixing a water soluble alkali metal silicate with an aqueous medium containing carefully controlled amounts of dissolved water soluble substances which are sources of calcium ion and magnesium ion, reacting the same to produce an aqueous colloidal suspension of the reaction product, admixing a micelle-forming surfactant with the aqueous medium, and agitating the aqueous medium containing the colloidal particles and surfactant to form catalyst containing micelles. | ||||||
| 76 | Asphalt paving compositions from positive spot asphalt fractions | US528440 | 1974-11-29 | US3939004A | 1976-02-17 | Luke W. Corbett |
| Asphalt fractions unsuitable for use in paving formulations because of their inhomogeneity (as reflected by their inability to pass the Oliensis Spot Test) can be used to make homogeneous asphaltic compositions (which pass the Oliensis Spot Test) by combining them with a propane precipitated asphalt and/or petrolene fraction. The latter fractions must have a polar aromatic content of at least 20%. Optionally up to 10% vacuum gas oil can also be added to the compositions. These upgraded asphaltic compositions have a polar aromatic content of at least 30% and are useful in paving formulations. | ||||||

| The hydrocarbonaceous substance, e.g., a petroleum asphalt cement such as a residual, pitch, Trinidad asphalt, etc., is composited with an oil shale which has been ground to an average particle size of less than about 75 microns and then eminently admixed with the hydrocarbonaceous material at a temperature in the approximate range 250*-375*F.

| A bituminous composition, capable of being sprayed at ambient conditions and particularly useful as a soil stabilizer, including, a major proportion of a highly aromatic, bituminous material, such as thermally cracked pitch, in an amount between about 35 percent and 75 percent, a predominantly paraffinic solvent, such as kerosene, in an amount between about 15 percent and 35 percent, a predominantly naphthenic solvent, such as naphtha, in an amount between about 5 percent and 20 percent, and methylene chloride, in an amount between about 5 percent and 20 percent; and the method of preparing this composition, including, heating the bituminous material to a temperature above its melting point and pumping the same into a blending tank equipped with cooling coils and an impeller-type mixer, immediately adding the paraffinic solvent to the bituminous material at a slow rate while agitating and cooling, thereafter adding the naphthenic solvent to the mixture when the temperature of the mixture reaches a point above 25* F. below the boiling point of the naphthenic solvent, agitating and cooling the mixture until the mixture reaches a temperature between about 100 and 105* F., and slowly adding the methylene chloride, while continuing cooling to essentially ambient temperature over an extended period of time, such as 30 minutes.
