资料简介

工业上使用二氧化碳(参见7.3节)作为气体或 液体或作为生产化学品的原料可以 有助于将捕获的CO2排除在大气层之外 储存在人造碳产品中。工业用途 提供碳汇,只要池的大小保持增长 所合成的化合物的寿命长。既不 由于CO2的规模,所以在实践中满足先决条件。 与人为二氧化碳排放量相比,利用率很小, 而且所生产的化学品的寿命太短 关于二氧化碳储存的兴趣范围。因此, 工业利用捕获的CO2对缓解的贡献 预计气候变化的规模会很小。

The industrial use of CO2 (see Section 7.3) as a gas or a liquid or as feedstock for the production of chemicals could contribute to keeping captured CO2 out of the atmosphere by storing it in anthropogenic carbon products. Industrial uses provide a carbon sink, as long as the pool size keeps growing and the lifetime of the compounds produced is long. Neither prerequisite is fulfilled in practice, since the scale of CO2 utilization is small compared to anthropogenic CO2 emissions, and the lifetime of the chemicals produced is too short with respect to the scale of interest in CO2 storage. Therefore, the contribution of industrial uses of captured CO2 to the mitigation of climate change is expected to be small.
