20190322529 · 2019-10-24 ·

Described herein are processes and apparatus for the large-scale synthesis of boron nit ride 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.

Production process for silicon carbide

Inside a furnace body with a vacuum environment or under the inert gas protection, the raw silicon material used to produce silicon carbide is melted or vaporized in a high temperature environment over 1300 C., and then the melted or vaporized raw silicon material will react with the carbonaceous gas or liquid to form silicon carbide. The present invention uses the carbonaceous gas with no metallic impurities, to replace petroleum coke, resin, asphalt, graphite, carbon fiber, coal, charcoal and some other carbon sources used in current production processes. When the carburizing reaction is in progress, the raw silicon material is melted or vaporized and the reaction takes place in the air. No container is required, so impurity contamination is lessened, and the produced silicon carbide has a fairly high purity.

Plasma frequency trigger
10385468 · 2019-08-20 · ·

An exothermic reaction of hydrogen/deuterium loaded into a metal or alloy is triggered by controlling the frequency of a hydrogen/deuterium plasma in a reaction chamber. The plasma frequency is controlled by adjusting its electron density, which in turn is controlled by adjusting the pressure within the reaction chamber. An exothermic reaction is generated at certain discrete plasma frequencies, which correspond to the optical phonon modes of D-D, H-D, and HH bonds within the metal lattice. For example, in palladium metal, the frequencies are 8.5 THz, 15 THz, and 20 THz, respectively.

PLASMA/IONIC REACTOR FOR PROCESSING FLUOROCARBON MATERIALS
20240165448 · 2024-05-23 ·

A plasma or ionic reactor or gasifier implements an ultra-high temperature ionic gasification process that can be used in an environmentally friendly manner to dispose of dried biosolids from, for example, wastewater treatment plants as well other waste feed stocks such as municipal solid waste (MSW) to produce, for example, renewable syngas that can be used to provide heat, power, renewable fuels, renewable hydrogen, and/or renewable chemical production. The systems described herein do so by generating electrical arcs across the interior of the gasifier reaction chamber creating a localized, controlled temperature in excess of 3000 C along with ionic gas or particles (plasma). This ultra-high temperature gasification zone and active ionic environment combine to very effectively and efficiently break down molecules into their constituent atoms, in a process called complete molecular dissociation. This ultra-high temperature ionic zone will also rapidly decompose impurities in the feed stock such as microplastics, PFAS (Per- and Polyfluorinated Substances), and other fluorocarbon materials.

Carbon black generating system

Apparatus and process for the continuous production of carbon black or carbon containing compounds.

There is no significant recirculation of feedstock into the plasma chamber, and the reaction zone does not immediately come into contact with any contact surfaces. The products of reaction are cooled, and the carbon black or carbon containing compounds are separated from the other reaction products.
