摘要

在全球积极应对气候变化的背景下，发展高效的碳捕集技术对于实现“碳中和”目标至关重要。为研究利用介质阻挡放电（DBD）技术优化粉煤灰基催化剂结构的可行性，进而提高其对单乙醇胺溶液CO

解吸的催化性能，采用响应面法分析了电压、处理时间和N

流量对粉煤灰基催化剂催化性能的影响。结果表明，DBD处理能显著优化催化剂的织构性质并优化活性位点。在电压27 kV、处理时间646 s和N

流量111 mL/min的最优条件下制备的Ni/FA-a-DBD（FA和a分别代表粉煤灰和碱改性）表现出较好的催化性能，其平均CO

解吸量提升率为16.53%（与Ni/FA-a相比）。

Abstract

In the context of global active response to climate change

the development of efficient carbon capture technologies is essential for achieving “carbon neutrality”. To explore the feasibility of optimizing the structures of fly ash‑based catalysts via dielectric barrier discharge (DBD) technology and thereby enhancing their catalytic performances for CO

desorption from monoethanolamine solutions

response surface methodology was adopted to analyze the effects of voltages

treatment time and N

flow rates on the catalytic performances of fly ash-based catalysts. The results demonstrate that DBD treatment can significantly refine the textural properties of the catalysts and optimize their active sites. Ni/FA-a-DBD (FA and a represent fly ash and alkali modification

respectively) prepared under the optimal conditions of voltage of 27 kV

treatment time of 646 s and N

flow rate of 111 mL/min exhibits favorable catalytic performance

with average enhancement rate of 16.53% (compared with Ni/FA-a) for CO

desorption capacity.
