摘要： Systems and methods for producing hydrogen and solid carbon from gaseous feedstock. The system includes a plasma reactor configured to receive and convert feedstock comprising hydrocarbons into acetylene-containing feed stream, and a refractory coupled to the plasma reactor that is configured to receive and decompose acetylene to hydrogen and solid carbon. The system is further configured to deliver one or more auxiliary feedstock comprising hydrocarbons directly to the refractory for decomposition into hydrogen and carbon. The energy required to decompose the auxiliary feedstock is provided by the energy released from decomposition of acetylene in the refractory.

摘要： Disclosed is a system and method related to removal of carbon from carbon dioxide via the use of plasma arc heating techniques. The method involves generating C atoms and H atoms from CxHy. The method involves generating graphite and H2 from the C atoms and H atoms, and extracting the graphite. The method involves quenching the H2 with CxHy. The method involves receiving, at a generator, the quenched the H2 and CxHy and generating electricity. The method involves generating a concentrated stream of H2 from the quenched H2 and CxHy. The method involves receiving CO2 and the concentrated stream of H2 and generating C, O, and H atoms. The method involves receiving the C, O, and H atoms and generating graphite, wherein the graphite is extracted. In the hydrocarbon CxHy: x is an integer 1, 2, 3, . . . , and y=2x+2.

摘要： Described herein are processes and apparatus for the large-scale synthesis of boron nitride nanotubes (BNNTs) by induction-coupled plasma (ICP). A boron-containing feedstock may be heated by ICP in the presence of nitrogen gas at an elevated pressure, to form vaporized boron. The vaporized boron may be cooled to form boron droplets, such as nanodroplets. Cooling may take place using a condenser, for example. BNNTs may then form downstream and can be harvested.

摘要： An alternative process and device for carrying out Fischer Tropsch (FT) syntheses is proposed, allowing the reactant entities that take part in the FT reaction to be activated and their contributions, whether by quantity or by proportion, to be adjusted. The process consists in making a particulate phase, optionally consisting of catalytic particles, flow through a reactor. While flowing through the reactor, the particulate phase is subjected at regular intervals to the action of a plasma obtained from a gas, such as hydrogen, thus enabling hydrogen activation for hydrogenation of carbon monoxide, or carbon monoxide activation in order to lengthen the carbon chains.

摘要： The present disclosure relates to a spark plasma sintering-joined polycrystalline diamond and methods of joining polycrystalline diamond segments by spark plasma sintering. Spark plasma sintering produces plasma from a reactant gas found in the pores in the polycrystalline diamond segments. The plasma forms diamond bonds and/or carbide structures in the pores, which join the polycrystalline diamond segments to form a polycrystalline diamond element.
