Particles with suitable properties may be generated using systems and methods provided herein. The particles may include carbon particles.

Carbon blacks such as reinforcing-grade carbon blacks with high structure are described. The carbon black can have the following properties: a statistical thickness surface area (STSA) ranging from 80 m.sup.2/g to 150 m.sup.2/g, an oil absorption number (OAN) of at least 180 mL/100 g, and a crushed oil absorption number (COAN) of at least 110 mL/100 g. Rubber compounds which incorporate the carbon black also are described.

Carbon nanoparticles made in a one step process. A method of making carbon black nanoparticles is described, including adding a hydrocarbon to a heated gas to produce carbon nanoparticles that are less than 1 micron volume equivalent sphere and have an Lc greater than 3.0 nm. Elastomer composites containing such particles are also described.

Disk shaped fine carbon particles. A fine carbon particle having a diameter of less than 3 microns and a height of less than 0.05 micron substantially in disk form are described. Admixtures with other fine particles are also described.

Methods to produce carbon black from low-yielding carbon black feedstocks are described. Carbon blacks produced from these carbon black feedstocks are further described. The advantages achieved with the methods are further described.

A plant for producing hydrogen from scission of methane molecules with production of carbon dust includes a reactor having an inner chamber delimited by a holding wall. The reactor includes an inlet opening for feeding methane (CH4), an outlet opening for allowing hydrogen (H2) in gaseous form to flow out. A discharge opening is for discharging carbon dust (C) from the inner chamber through a sealing rotary valve. A refractory lining, and an electromagnetic induction heater are for heating the inner chamber of the reactor.
