Aging resistant asphalt compositions and related methods of preparing and applying the same are provided. The aging resistant asphalt compositions can include a base asphalt with specified properties combined with an aging resistance additive, to produce modified asphalt compositions having a colloidal index within the range of about 3.7 to about 8.0, a saturates content of less than about 10% by weight, and measurable age-resistant properties. The aging resistant asphalt compositions are useable in a variety of asphalt paving and non-paving applications. The aging resistant asphalt compositions provide improved resistance to both moderate and low failure temperatures of conventional paving asphalts throughout its service life by reducing age-related failures.

The present disclosure generally relates to scavenging hydrogen sulfide. The disclosure pertains to non-aqueous and non-volatile compositions that include a monolignol alcohol and hydrogen sulfide scavenging compound. The hydrogen sulfide scavenging compound may be hexamine in some aspects. The compositions may also include a C.sub.2-8 polyol. The compositions disclosed are stable and can be used, for example, in removing hydrogen sulfide from hot asphalt.

The invention relates to a surfactant composition comprising an ionic liquid prepared from an unsubstituted or substituted primary, secondary or tertiary amine, or from an unsubstituted or substituted pyridine, amidine or guanidine with at least one fatty acid and/or resin acid. The invention also relates to a method for treating bitumen froth from a separation process, where bitumen is separated from mineral solids. The method comprises addition of said surfactant composition to the diluent and/or to the froth before phase separation.

A method and apparatus are provided for processing hydrocarbon coal slurry feeds. The method and apparatus enhance the conversion of the coal feeds into useful conversion products, such as high melting and high carbon containing pitch products. In particular, the present techniques utilize a specially designed “self-cleaning” and “wall-catalyzed” preheater-reactor systems.

An integrated method for mesophase pitch and petrochemicals production. The method including supplying crude oil to a reactor vessel; heating the crude oil in the reactor vessel to a predetermined temperature for a predetermined amount of time; reducing asphaltene content in the crude oil by allowing polymerization reactions to occur in the reactor vessel at an elevated pressure in the absence of oxygen; producing a three-phase upgraded hydrocarbon product comprising gas, liquid, and solid hydrocarbon components, where the liquid hydrocarbon component comprises deasphalted oil and the solid hydrocarbon component comprises mesophase pitch; separating the gas, liquid, and solid hydrocarbon components; directly utilizing the liquid hydrocarbon component for petrochemicals production; and directly utilizing the solid hydrocarbon component for carbon artifact production.

The invention relates to a surfactant composition comprising an ionic liquid prepared from an unsubsituted or substituted primary, secondary or tertiary amine, or from an unsubstituted or substituted pyridine, amidine or guanidine with at least one fatty acid and/or resin acid. The invention also relates to a method for treating bitumen froth from a separation process, where bitumen is separated from mineral solids. The method comprises addition of said surfactant composition to the diluent and/or to the froth before phase separation.

Crosslink agents dispersible in oil or water for polymer modified asphalt. Sulfur is used in combination with hexamethylenetetramine and other adjuvants to form a powder compound suitable for use as is or dispersed in either oil or water.

The present disclosure relates to methods for preparing materials from heavy feedstocks. In particular, the disclosure provides a chemical process to convert heavy feedstocks with predominant polyaromatic hydrocarbon molecules or species, including the residues of petrochemical refining or extraction, into thermoset or thermoplastic materials that can be used alone or as a component in a composite material.

It has been discovered that contaminants such as metals and/or amines can be transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble C5-C12 polyhydroxy carboxylic acids, ammonium salts thereof, alkali metal salts thereof, and mixtures of all of these. The composition may also optionally include a mineral acid to reduce the pH of the desalter wash water. The method permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase under-carry into the aqueous phase. Resolving the emulsion into the hydrocarbon phase and the aqueous phase occurs in a refinery desalting process using electrostatic coalescence. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom. The polyhydroxy carboxylic acid additionally inhibits metal corrosion of metal pipe or other equipment used in a crude unit.

A method for processing bitumen froth to produce a diluted bitumen product having a reduced water and solids content is provided, comprising: adding a sufficient amount of water to the bitumen froth and mixing the bitumen froth and water to form a froth/water mixture; diluting the froth/water mixture with naphtha to form a diluted froth; and separating the water and solids from the diluted froth to produce the diluted bitumen product.
