Abstract
The present disclosure is related to the field of chemistry and provides methods and devices for stimulation of endothermic reactions in gas phase with high activation barriers by nanosecond pulsed electrical discharge. It can be used for, e.g., CO2 functionalization of methane, H2S dissociation, hydrogen and syngas production, for processing ammonia synthesis and dissociation, etc. Some embodiments include methods and devices associated with the stimulation of plasma chemical reactions with nanosecond pulse electric discharge in the presence of gas flow.
Claims8
A plasmachemical reactor with nanosecond pulse electric discharge generation, wherein the reactor comprises:
- one or more cylindrical channels having a gas input system and output system;
- a high voltage positive electrode and a high voltage negative electrode in each channel;
- and
- a gas swirling system in each channel for increasing local tangential gas velocity at electrodes ends;
- wherein
- the pulse electric discharge generation has a frequency f,
- the tangential gas velocity is greater than f*5*10−3 m/s, and
- wherein each high voltage positive electrode and each high voltage negative electrode has a cylindrical shape and at least one electrode has a tangential channel in the electrode body and a circular row of equal length rods on a flat end and at least one electrode having no tangential channel has a circular row of rods having lengths which decrease along a direction of gas rotation.
