Plasma Co-catalysis Evaluation System
TKSC-DBDC80 plasma synergistic catalytic evaluation system is suitable for ammonia synthesis, methane reforming, carbon dioxide to methanol, pollutant explanation and other reactions. The system breaks through the limitations of traditional thermodynamics through the synergistic effect of plasma activation and thermal catalysis to achieve high efficiency and low energy consumption of chemical reactions.
DBD Plasma Activation, Discharge Mechanism: Under a high-voltage AC electric field, gases (e.g., N2, H2, CH4) are ionised, generating high-energy electrons (1-15 eV), ions, free radicals and excited state molecules. Dielectric barrier layers (e.g., quartz, ceramics) limit the current and prevent arc discharge, forming uniform microdischarge filaments.
Active species generation: N2 activation: high-energy electrons dissociate N2 into N atoms (N), breaking through the high-energy barrier (~941 kJ/mol) of conventional thermal catalysis. H2 activation: generates H* free radicals, facilitating surface hydrogenation reactions. excited state molecules, reducing reaction activation energy.
Thermal catalysis enhancement, surface reaction: plasma-generated active species (N*, H*) adsorbed and reacted on the catalyst surface, generating target products (e.g., NH3, CH3OH) catalysts (e.g., Ru, Ni) to provide active sites, lowering the reaction energy barrier.
Synergistic effect: plasma locally heats the catalyst surface, forming micro-region high temperature (>800°C), accelerating reaction kinetics. Plasma induces defects on the catalyst surface (e.g. oxygen vacancies, nitrogen vacancies) and enhances the adsorption capacity. Plasma activation reduces the dependence on temperature and pressure, resulting in milder reaction conditions. Optimal matching of energy input and reaction efficiency is achieved by dynamically modulating the regulation of discharge parameters (frequency, voltage and thermocatalytic conditions (temperature, pressure).
Plasma-thermal catalysis synergy: breaking through the traditional thermodynamic limitations to achieve high efficiency reaction at low temperature and low pressure.
Modular design: convenient for laboratory research and industrial scale-up.
Intelligent control: dynamic optimisation of energy input and reaction conditions.
DBD plasma induces defects on the catalyst surface to enhance adsorption and activation capabilities; waste heat utilisation and dynamic power distribution enhance energy efficiency.
