Industrial application evaluation of electrocatalytic reduction of CO2 to olefin technology
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.
