目前以有机胺为吸收剂脱除 CO2的化学吸收法多存在氨基易分解、再生能耗高等不足。新型的 IVCAP 工艺采用碳酸钾水溶液吸收 CO2，可大幅节能降耗，但吸收速率较有机胺慢。碳酸酐酶是至今发现的最有效的 CO2水合酶催化剂，将该酶添加至 IVCAP 工艺中，可显著提高 CO2吸收速率。文中综述了固定化碳酸酐酶在碳捕集与封存技术中的研究和应用进展，并对其选用磁性载体材料强化 IVCAP 工艺对 CO2的捕集应用前景进行了展望。

Currently,the main drawbacks of the most available amine-based processes for post-combustion CO2 are amine degradation and parasitic power loss.A novel Integrated Vacuum Carbonate Absorption Process (IVCAP)was proposed to reduce the energy usage by employing a potassium carbonate aqueous solution as a solvent for CO2 absorption.However,K2 CO3 -based system has a much slower CO2 absorption rate than amine-based system does.Carbonic anhydrase is the most effective known enzyme by far that catalyzes the hydration of CO2 into bicarbonate and a proton.The research and applications of immobilized carbonic anhydrase were reviewed,and the application prospect of IVCAP process improvement for carbon dioxide capture by selecting magnetic carrier material was presented.
