摘要
在现有二氧化碳资源化利用路径中,电化学手段所需反应条件温和、产物选择性好,是打通绿色多能耦合链路,生产高附加值精细化学品的优选.武汉大学庄林、王功伟团队通过设计多功能聚合物电解质,成功实现采用工业级电流密度的二氧化碳/纯水共电解制乙烯技术.为评估该项技术的工业化前景,构建了物料平衡计算模型和技术经济性匡算框架.以实验数据为依据,计算了单位时间内反应装置原料消耗量与产物生成量,估算了采用该技术路线的万吨级乙烯装置生产收益情况,进行了相关技术参数对工业化收益的敏感性分析,明确了该技术工业化应用较为理想的场景,为二氧化碳/纯水共电解制烯烃技术工业化发展方向与市场化布局提供参考.
Abstract
In the existing path of CO2 resource utilization,electrochemical means prov ides good product selectivity but only requires mild reaction condition.It is a preferred choice of carbon resouce utilization for producing high-value chemicals.ZHUANG Lin and WANG Gongwei from Wuhan university has designed multi-functional polymer electrolyte,which enables the electrolysis of CO2 towards ethylene using industrial-scale current density.To evaluate its application prospects,a material-balance model and a techno-economic assess-ment framework have been constructed.The material consumption and production per unit time have been calculated to estimate the revenue of a 10 000 ton ethylene unit.Sensitivity analysis of technical parameters to revenue has been conducted.The ideal scenario for ap-plication of this technology has been identified.This study provides a reference for the in-dustrial development of CO2/pure water co-electrolysis towards olefins production.
