Thermal fracture and microcarbon separation of coal particles

A process for fracturing and devolatilizing coal particles rapidly exposes coal particles to a high temperature, oxygen-depleted work zone for a sufficient time period to cause volatile matter within the coal particles to vaporize and fracture the coal particles. The work zone has a temperature in the range from 600° C. to 2000° C. The coal particles are exposed to the high temperature, oxygen-depleted work zone for a time period less than 1 seconds, and preferably less than 0.3 second. The vaporized volatile matter is condensed and recovered as microcarbon particles.

20230042044 · 2023-02-09 ·

A method for forming mesophase pitch can include applying a stimulus to a first amount of coal tar to form a first amount of mesophase pitch. The stimulus can include one or more of an electromagnetic field (“EMF”) or a magnetic field. The method can further include evaluating a characteristic of the first amount of mesophase pitch, changing a parameter of the stimulus in response to evaluating the characteristic of the first amount of mesophase pitch, and applying the stimulus exhibiting the changed parameters to a second amount of coal tar to form mesophase pitch.

METHOD FOR MANUFACTURING COKE, COKE, AND METHOD FOR EVALUATING HOMOGENEITY OF COAL BLEND

A method for manufacturing coke having a high strength and excellent extrusion capability. The method includes a preparing step of blending two or more coal brands to prepare a coal blend, a stirring and mixing step of stirring and mixing the coal blend to disintegrate at least a part of pseudo-particles that have been formed by agglomeration of coal particles in the coal blend, and a carbonizing step of charging the stirred and mixed coal blend into a coke oven to carbonize the stirred and mixed coal blend. Additionally, a mixing apparatus is used in the stirring and mixing step that has a capability of controlling a degree of mixing of the coal blend to be 0.85 or more at 60 seconds after start of a mixing operation. The degree of mixing is calculated by the following equation (1):


degree of mixing=(σC.sub.0−σC)/(σC.sub.0−σCf)  (1).
