摘要
碳捕集技术目前被认为是减缓大气二氧化碳浓度的有前途的技术之一。二氧化碳捕集与利用(CCU)可以捕集人为产生的废弃二氧化碳,并将其转化为有用的产品,从而为实现碳中和的循环过渡途径提供支持。遗憾的是,二氧化碳的热力学稳定性要求在转化过程中输入高能量,从而导致过程产生净正碳足迹。在工艺中加入酶作为生物催化剂具有吸引力,因为这有利于在环境条件下进行二氧化碳转化。在自然界中,二氧化碳转化为有机化合物是通过光合作用进行的,使用的酶称为核酮糖-1,5-二磷酸羧化酶/氧化酶(RuBisCO)。RuBisCO 在二氧化碳的自然同化过程中发挥着核心作用,因此被自然界选为所有生命形式赖以生存的酶。然而,由于 RuBisCO 的羧化速度较慢(1-10/s),它被碳酸酐酶(CA)等羧化速度较快的酶所忽视,而碳酸酐酶的羧化速度为 106/s。尽管如此,RuBisCO 的速率增强仍比 CA 高 108 到 1010 倍。因此,本综述旨在更深入地了解 RuBisCO 并研究其在 CCU 中的潜力。本综述考虑了各个方面,如 RuBisCO 与其他酶相比的性能、克服其局限性的方法、其在 CCU 中的应用和影响、可从中提取的有价值化学品、RuBisCO 集成工艺的最新发展,以及其经济和环境考虑因素。通过这些,将探索 RuBisCO 作为 CCU 关键酶之一的潜力。
The potential of RuBisCO in CO2 capture and utilization
Carbon capture technology is currently considered one of the promising technologies to mitigate atmospheric CO2 concentration. CO2 capture and utilization (CCU) captures anthropogenic waste CO2 and valorizes it into useful products, supporting a circular transition pathway towards carbon neutrality. Unfortunately, the thermodynamic stability of CO2 requires a high-energy input for its conversion, resulting in processes with a net positive carbon footprint. The incorporation of enzymes as biocatalysts in a process is attractive, as it facilitates CO2 conversion under ambient conditions. In Nature, the conversion of CO2 into organic compounds is done through photosynthesis, using an enzyme called ribulose-1,5-biphosphate carboxylase/oxygenase (RuBisCO). RuBisCO plays a central role in the natural assimilation of CO2, making it the enzyme chosen in Nature upon which all life forms depend. However, the slow carboxylation rate of RuBisCO (1–10/s) has caused it to be overlooked by faster enzymes such as carbonic anhydrase (CA), which has a carboxylation rate of 106/s. Despite this, RuBisCO has a rate enhancement of 108 to 1010 times higher than CA. Thus, this review aims to take a closer look at RuBisCO and examine its potential in CCU. Various aspects are considered, such as RuBisCO’s performance in comparison to other enzymes, approaches to overcome its limitations, its applications and implications in CCU, the valuable chemicals that can be derived from it, recent developments in RuBisCO-integrated processes, and its economic and environmental considerations. Through this, RuBisCO’s potential as one of the key enzymes in CCU will be explored.
期刊介绍:
Progress in Energy and Combustion Science (PECS) publishes review articles covering all aspects of energy and combustion science. These articles offer a comprehensive, in-depth overview, evaluation, and discussion of specific topics. Given the importance of climate change and energy conservation, efficient combustion of fossil fuels and the development of sustainable energy systems are emphasized. Environmental protection requires limiting pollutants, including greenhouse gases, emitted from combustion and other energy-intensive systems. Additionally, combustion plays a vital role in process technology and materials science.
PECS features articles authored by internationally recognized experts in combustion, flames, fuel science and technology, and sustainable energy solutions. Each volume includes specially commissioned review articles providing orderly and concise surveys and scientific discussions on various aspects of combustion and energy. While not overly lengthy, these articles allow authors to thoroughly and comprehensively explore their subjects. They serve as valuable resources for researchers seeking knowledge beyond their own fields and for students and engineers in government and industrial research seeking comprehensive reviews and practical solutions.
