Abstract
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.
Claims19
A method for forming mesophase pitch, comprising:
- continuously providing coal tar to a reactor;
- applying a stimulus to an amount of the coal tar, the stimulus selected from the group consisting of at least one of an electromagnetic field (“EMF”) or a magnetic field, wherein applying the stimulus to the amount of coal tar heats the amount of coal tar to a temperature of from about 100° C. to about 300° C.;
- and
- continuously forming mesophase pitch from the coal tar.
A method for processing coal tar, comprising:
- evaluating a characteristic of an amount of coal or an amount of coal tar formed from the amount of coal;
- selecting one or more parameters of a stimulus in response to evaluating the characteristic;
- and
- applying a stimulus having the one or more parameters to the amount of coal tar to form mesophase pitch, the stimulus selected from the group consisting of at least one of an electromagnetic field (“EMF”) or a magnetic field, wherein applying the stimulus to the amount of coal tar heats the amount of coal tar to a temperature of from about 100° C. to about 300° C.
A method for forming mesophase pitch, comprising:
- applying a stimulus to a first amount of coal tar to form a first amount of mesophase pitch, the stimulus selected from the group consisting of at least one of an electromagnetic field (“EMF”) or a magnetic field, wherein applying the stimulus to the amount of coal tar heats the amount of coal tar to a temperature of from about 100° C. to about 300° C.;
- 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 a second amount of mesophase pitch.
