二氧化碳(CO_2)是有机物质及化石燃料燃烧的主要产物,同时也被认为是造成温室效应及全球变暖的主要成分之一,约占温室气体的2/3。在世界CO-2排放量逐年递增的今天,研究开发CO-2处理利用方法显得尤其重要,与CO_2地下封存相比,CO_2制备化工产品可实现CO_2的循环利用,因而更具应用前景。本文对近期CO_2制化学品技术的研究进展情况进行了简要总结。 Carbon dioxide (CO 2) is the main product of combustion of organic matter and fossil fuels. It is also considered as one of the major components that contribute to the greenhouse effect and global warming, accounting for about two thirds of greenhouse gases. Nowadays CO-2 treatment and utilization research and development in the world are becoming more and more important. The CO 2 preparation chemical products can realize the recycling of CO 2 compared with CO 2 underground storage, so it has more application prospects. This article briefly summarizes the research progress of recent CO 2 chemical technology.
