A process and reactor for removing impurities from a carbon material, involving providing a carbon feed into the electrothermal reactor; providing a gas into the reactor; passing the carbon feed through the reactor in a direction; heating the carbon feed using one or more electrodes; volatizing non-carbon material of the feed with the heat; and discharging the purified carbon material at the second location. So purified, the carbon material may be battery-grade. The feed may be passed through the reactor in a generally horizontal direction. The velocity of the feed in the reactor may be controlled to achieve a select resident time sufficient to volatize a desired amount of impurity. The process and reactor may be configured to inhibit back-mixing of the feed.

Disclosed herein is a photoreactor design having an optically accessible reactor chamber with a short gas flow residence time for carrying out gas-phase catalytic reactions under light illumination. A vertically arranged reactor is provided with a lighting source, a horizontally arranged thin catalyst bed layer supported on a gas-permeable bounding plate through which gas is passed in the vertical direction, and in which incident photons from the light source are perpendicular to the horizontally arranged thin catalyst bed layer. The described technology is intended to enable a number of industrially relevant chemical reactions to proceed under light illumination on the surface of metal photocatalysts with efficiencies and selectivity beyond that dictated by thermodynamic equilibrium in conventional thermal catalysis in the heat-powered plants.

The present invention relates, in general, to a system and method for focusing gas distribution through at least one three-dimensionally (3D) printed lattice heating elements within an electric catalyst unit to promote ammonia dissociation. The present invention allows gaseous ammonia to be continuously heated under turbulence as it flows through non-linear paths within a 3D printed lattice heating element. The lattice structure of the heating element provides a balance between surface area and heat dissipation, allowing the heating elements to reach a suitable temperature to perform ammonia dissociation, but which are not oversaturated with heat which could result in failure or melting of the heating element.
