摘要

Abstract

The plasma-coupled electrocatalytic cascade technology with NO

as intermediate product is a potential method to realize green ammonia synthesis. The matching of the formation rate and consumption rate of NO

as the main absorption product is an important prerequisite for the system to achieve stable operation. Therefore

this paper firstly emphasizes the importance of operating parameters on the cascade system based on the single factor experiment. Secondly

the empirical equation between electrocatalytic operating conditions and NO

consumption rate was established by response surface analysis. Based on this equation

the electrocatalytic operating parameters were optimized to achieve the dynamic equilibrium between NO

formation rate and consumption rate. Finally

the techno-economic assessment model was established to calculate the levelized cost of ammonia based on the cascade system

and the single-variable sensitivity analysis was performed to provide the clear guidance for cost reduction.
