摘要： Provided are methods for preparing hydrogen and solid carbon. Illustrative methods comprise providing a feedstock comprising gaseous hydrocarbons to a microwave-inert reaction vessel and/or a radio wave-inert reaction vessel. The reaction vessel has solid carbon, about 0% water and about 0% molecular oxygen inside the reaction vessel and the carbon inside the reaction vessel is operable to heat the feedstock comprising gaseous hydrocarbons. The carbon is then exposed to microwaves and/or radio waves until the solid carbon is at a temperature of at least 1200 Kelvin, thereby forming hydrogen and solid carbon. Once formed, the hydrogen and solid carbon are separated.

摘要： 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.

摘要： Herein disclosed are apparatus and associated methods related to producing an enhanced surface area biochar product with a desired activation level based on receiving biochar into a processing vessel configured with multiple independently temperature-controlled chambers and counter-flow steam injection, controlling activation levels of the biochar by moving the biochar through the processing vessel and adjusting the temperature of the biochar by injecting steam into at least one temperature-controlled chamber of the processing vessel, recovering volatiles driven off through dehydration using a thermal oxidizer, cooling the biochar to a desired discharge temperature using steam and retention time, and discharging the activated biochar product. The processing vessel may be a calciner, a rotary calciner, or a kiln. Biochar may be heated or cooled to a desired thermochemical processing temperature depending on the temperature of the received biochar. Counter-flow saturated steam may sweep volatile gases to a thermal oxidizer using a vacuum system.

摘要： The present disclosure relates to a method for producing metallurgical coke from non-coking coal. The method comprising, densifying, the non-coking coal to form pellets. The densified pellets will be placed in a microwave oven within plurality of bricks and are subjected for pyrolysis. For carrying our pyrolysis, the pellets are carried out by heating, the pellets in the microwave oven at a predetermined temperature under an inert atmosphere at atmospheric pressure, and then the pellets are cooled in the microwave oven under the inert atmosphere. This process coverts non-coking coal to the metallurgical coke in a quicker time, and without use of any susceptors.
