CO2 conversion covers a wide range of possible application areas from fuels to bulk and commodity chemicals and even to specialty products with biological activity such as pharmaceuticals. In the present review, we discuss selected examples in these areas in a combined analysis of the state-of-the-art of synthetic methodologies and processes with their life cycle assessment. Thereby, we attempted to assess the potential to reduce the environmental footprint in these application fields relative to the current petrochemical value chain. This analysis and discussion differs significantly from a viewpoint on CO2 utilization as a measure for global CO2 mitigation. Whereas the latter focuses on reducing the end-of-pipe problem “CO2 emissions” from todays’ industries, the approach taken here tries to identify opportunities by exploiting a novel feedstock that avoids the utilization of fossil resource in transition toward more sustainable future production. Thus, the motivation to develop CO2-based chemistry does not depend primarily on the absolute amount of CO2 emissions that can be remediated by a single technology. Rather, CO2-based chemistry is stimulated by the significance of the relative improvement in carbon balance and other critical factors defining the environmental impact of chemical production in all relevant sectors in accord with the principles of green chemistry.

二氧化碳的可持续转化:催化和生命周期评估的综合综述

从燃料到散装和日用化学品,甚至到具有生物活性的特种产品(例如药品),CO 2转化涵盖了广泛的可能应用领域。在本综述中,我们将对综合方法和流程的最新技术及其生命周期评估进行综合分析,以讨论这些领域中的精选示例。因此,我们试图评估相对于当前石化价值链而言,在这些应用领域中减少环境足迹的潜力。从作为整体CO 2缓解措施的CO 2利用率的观点来看,这种分析和讨论有很大不同。而后者侧重于减少管道末端问题“ CO 2排放”来自当今行业,此处采取的方法试图通过开发新型原料来寻找机会,该原料避免了在向更可持续的未来生产过渡的过程中利用化石资源。因此,发展基于CO 2的化学的动机并不主要取决于可以通过单一技术补救的CO 2排放的绝对量。相反,基于碳平衡的相对改善的重要性以及根据绿色化学原理定义所有相关行业的化学生产对环境的影响的其他关键因素,会刺激基于CO 2的化学。
