While experts in various fields discuss the potential of carbon capture and storage (CCS) technologies, the utilization of carbon dioxide as chemical feedstock is also attracting renewed and rapidly growing interest. These approaches do not compete; rather, they are complementary: CCS aims to capture and store huge quantities of carbon dioxide, while the chemical exploitation of carbon dioxide aims to generate value and develop better and more-efficient processes from a limited part of the waste stream. Provided that the overall carbon footprint for the carbon dioxide-based process chain is competitive with conventional chemical production and that the reaction with the carbon dioxide molecule is enabled by the use of appropriate catalysts, carbon dioxide can be a promising carbon source with practically unlimited availability for a range of industrially relevant products. In addition, it can be used as a versatile processing fluid based on its remarkable physicochemical properties.
虽然各个领域的专家都在讨论碳捕获和储存 (CCS) 技术的潜力，但二氧化碳作为化学原料的利用也重新引起了人们的极大兴趣。这些方法并非相互竞争，而是相辅相成的：CCS 的目的是捕获和储存大量的二氧化碳，而二氧化碳的化学利用则旨在从有限的废物流中产生价值并开发更好、更高效的工艺。只要基于二氧化碳的工艺链的总碳足迹具有竞争力，并且二氧化碳分子的反应可以通过使用适当的催化剂来实现，那么二氧化碳就可以成为一种有前途的碳源，对于一系列具有工业相关性的产品来说，其可用性几乎是无限的。此外，由于其显著的物理化学性质，二氧化碳还可以用作多功能加工流体。
