Gas-Phase Conversions

Nanoplazz Technologies has developed a breakthrough plasma-based chemical reactor for gas-phase conversions capable of extraordinary selectivity and energy efficiency
A high temperature plasma reactor is powerful tool to drive endothermic chemical reactions with high activation energies. Temperatures within electric discharges can rise from more than a few up to greater than ten thousand degrees. The high energies of the reactants at such temperatures easily overcome activation energies and push the chemical equilibrium towards the products.
Gas-Phase High-Temperature Nanosecond-Pulsed Plasma Reactor
Our plasma reactor generates a continuous series of electric breakdowns of gas to plasma across two electrodes. The reactant gases flow through an input gas module from the cathode to the anode. The breakdowns appear as thin filaments which form and extinguish in less than 20 nano-seconds each time in a new place in the gas flow. The proprietary gas input module design generates a vortex that helps stabilize the discharges between electrodes. Because these short-lived discharges allow products to escape hot zones very quickly, the reactor represents a natural and efficient solution for the quenching problem and ensuring high selectivity to desired products.
 
The power supply design enables the nanosecond discharges at a high frequency, typically from 50 to 100 kHz. The supply utilizes a proprietary design to achieve high energy efficiency in converting simple AC power to high voltage, high current, short-lived pulses. The electrodes have been designed to achieve a long lifetime.
 
Most components of the reactor are constructed of common, low-cost materials. The overall design is simple and amenable to modular construction. The reactors are scalable and additional capacity can be added simply by adding another reactor.  The installed cost of modules will be very competitive with thermo-catalytic reactors. The high energy efficiency and high selectivity enable simple and cost-effective process design concepts. Downstream separation and purification unit operations are minimized.

Value Proposition: Low cost production with low or no GHG emissions
Nanoplazz Technologies’ plasma reactor creates an opportunity to attack specific industry challenges in advantaged ways. The technology allows industry producers to avoid high temperature, high pressure catalytic systems requiring expensive metallurgy or the use of expensive catalysts that require regular replacement. The use of renewable power offers a simple way to reduce or eliminate greenhouse gas emissions and produce carbon-neutral or low-carbon fuels and chemicals.

Competitive Advantage

Nanoplazz Technologies’ approach to quenching has proven to be more effective than other methods including direct water injection and wall heat transfer. Our plasma energy efficiencies (heat of reaction/energy cost) measured in laboratory experiments are significantly higher than those reported in the literature for identical reactions. A simple reactor design that achieves translates into ease of reactor manufacturability using a modular approach with low cost materials of construction.  High energy efficiency and high selectivity translate into limited downstream unit operations. Aspen Plustm modeling and techno-economic analyses suggest that as renewable power prices continue to fall, production by plasma reactor will soon be lower cost than conventional thermo-catalytic approaches.
