A method for preparing a solid bitumen material at ambient temperature, the method comprising at least the steps of: a) preparing a stabilized emulsion of bitumen drops in a water phase that has a pH of 2 to 4; b) preparing a silica sol or silica gel from a first silicon oxide precursor that has a pH of 2 to 4; c) mineralizing the emulsion of bitumen drops from step a) with the silica sol or gel from step b); d) mineralizing the emulsion of bitumen drops from step c) having a maximum pH of 1 with a second silicon oxide precursor; e) separating the material from the water phase.

A method for producing a non-coalescing asphalt from raw natural asphalt herein referred to as TLA Cold Milled. Raw TLA is crushed into smaller particles and milled at ambient temperature. The milled TLA is passed through a first sieve to maintain the separation of the particles and to produce a damp milled TLA in a powdered state. The damp milled powdered TLA is dried by exposing it to heat and is thereafter cooled to ambient temperature. The dried and cooled powdered TLA is passed through the first sieve or another sieve to produce the TLA Cold Milled which may be packaged at ambient temperature in conventional bags. The milling of the asphalt results in each particle of inorganic matter within the asphalt being surrounded by bitumen and a thin film of inorganic material, producing asphalt in a non-coalescing form, i.e., the TLA Cold Milled.

Granular bitumen that is solid at ambient temperature includes a core and a coating layer that covers all or part of the surface of the core, wherein the core includes at least one bitumen base, and the coating layer includes at least one viscosifying compound and at least one anticaking compound. A method for manufacturing bitumen that is solid at ambient temperature and the use of bitumen that is solid at ambient temperature as a road binder, particularly for manufacturing asphalts. Further, a method for manufacturing asphalts from solid bitumen and to a method for transporting and/or storing road bitumen that is solid at ambient temperature.

Methods, processes, and apparatuses for preparing and transporting bitumen. Bitumen may be prilled such that a bitumen product comprising a prill core and a non-stick coating is produced. The non-stick coating may comprise asphaltenes and the prill core may comprise bitumen, deasphalted oil, or both bitumen and deasphalted oil. The resultant non-stick coated prills have reduced adhesion to transportation vessels and other non-stick coated prills at a temperature below an adhesion temperature, facilitating transport.

The present disclosure relates to a method of preparing an anisotropic pitch for carbon fiber, and more particularly, to a method of preparing an anisotropic pitch of preparing a pitch having a low softening point by thermally polymerizing heavy oil or residue oil generated in an oil refining process, extracting only a mesogen component, and then heat-treating at a high temperature for a short time. The anisotropic pitch prepared in the present disclosure has advantages of exhibiting the anisotropic content of 100% and controlling the anisotropic content only a simple temperature control as desired and may be used as a precursor of a high value-added carbon material such as carbon fiber and an anode material for a lithium secondary battery.
