Abstract: The present invention is an apparatus and method for continuously separating, removing and purifying the solid residue, resulting from the conversion of hydrocarbons into carbon and hydrogen, from the homogeneous phase of different density contained in a cracking reactor with which said solid residue is not soluble, and where the separation of the solid carbon occur at two subsequent moments: a first separation occurs inside the reactor between the reaction products, including carbon, and the melting bath; a second separation then occurs outside the reactor between the carbon and the gas produced in a separation system (1) of the solid phase from the gas phase, where said separation system (1) also includes carbon purification.

Abstract: 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.

Abstract: High quality, catalyst-free boron nitride nanotubes (BNNTs) that are long, flexible, have few wall molecules and few defects in the crystalline structure, can be efficiently produced by a process driven primarily by Direct Induction. Secondary Direct Induction coils, Direct Current heaters, lasers, and electric arcs can provide additional heating to tailor the processes and enhance the quality of the BN-NTs while reducing impurities. Heating the initial boron feed stock to temperatures causing it to act as an electrical conductor can be achieved by including refractory metals in the initial boron feed stock, or providing additional heat via lasers or electric arcs. Direct Induction processes may be energy efficient and sustainable for indefinite periods of time. Careful heat and gas flow profile management may be used to enhance production of high quality BNNT at significant production rates.
