Abstract: A process for preparing activated carbon includes combining crushed petroleum coke (petcoke) with non-aqueous potassium hydroxide. The petcoke and the potassium hydroxide are then heated to a sub-activation temperature to yield a pre-activated blend. Under substantially inert conditions, the preactivated blend is then heated to at least the activation temperature of the petcoke to yield a first-stage activated blend. The first-stage activated blend includes activated carbon of a first microporosity percentage. The first-stage activated blend is then cooled to below the activation temperature of the petcoke. Under substantially inert conditions, the first-stage activated blend is then re-heated to at least the activation temperature of the petcoke to yield a second-stage activated blend. The second-stage activated blend includes activated carbon of a second microporosity percentage that is less than the first microporosity percentage. The steps of cooling and reheating may be repeated serially, to tailor the microporosity of the activated carbon.

Abstract: The present disclosure relates to a method of treating hydrocarbon materials with thermoplastic nature that are liquid at room temperature or become liquid upon heating, to increase their softening point temperature up to 400° C. The method includes the steps of mixing a sulfur-containing gaseous catalyst with the hydrocarbon material in an environmentally controlled reactor, Heating the mixture to a temperature between 280° C. and 480° C. in a flowing gas environment and holding the mixture at this temperature for a period of time from 2 hours to 5 hours and stirring the mixture and maintaining stirring until the hydrocarbon material becomes solid.

Abstract: There is provided a process and system for producing carbon fiber products. The process can involve deasphalting a heavy hydrocarbon feedstock, which can contain native asphaltenes, to produce a solid asphaltene particulate material, which can be further treated to produce the carbon fiber products. In some implementations, the solid asphaltene particulate material can be extruded in the presence of a polymer. In some implementations, the solid asphaltene particulate material can be chemically treated with a chemical agent including a Lewis acid, an oxidizing agent and/or a reducing agent before extrusion. In some implementations, the process can further produce activated carbon fibers.

Abstract: A process gas (such as a hydrocarbon gas) is flowed through a thermal cracking apparatus to crack the process gas into constituent components (such as hydrogen gas and solid carbon nano-particles, e.g., carbon nano-onions, necked carbon nano-onions, carbon nanospheres, graphene, graphite, highly ordered pyrolytic graphite, single walled nanotubes, and/or multi-walled nanotubes). The thermal cracking apparatus has an elongated heating element disposed within an inner volume along a longitudinal axis thereof. The elongated heating element heats the process gas as it flows within a longitudinal elongated reaction zone to thermally crack molecules of the process gas into the constituent components of the molecules.

Abstract: An electrode for an electrochemical device includes porous carbon particles. In a pore distribution of the porous carbon particles, a ratio B/A of an integrated volume B to an integrated volume A ranges from 1 to 1.5, inclusive. The integrated volume A is an integrated volume of pores each having a pore diameter of more than or equal to 1 nm and less than 2 nm. The integrated volume B is an integrated volume of pores each having a pore diameter of more than or equal to 2 nm and less than or equal to 50 nm. A volume-based particle diameter frequency distribution of the porous carbon particles has a first peak and a second peak. A particle diameter corresponding to the second peak is larger than a particle diameter corresponding to the first peak.
