高含二氧化碳天然气化工综合利用

Comprehensive utilization chemically of high-carbon natural gas

高含CO2天然气是一种非常规天然气资源,因其CO2含量高而难以直接利用。为此,本文针对此类天然气中所含的CO2能够弥补一般天然气缺碳多氢的缺点,尤其符合由天然气制丙烯过程中补碳的要求,提出充分利用CO2和这类天然气资源的途径。本文分析了高含CO2天然气化工的利用途径,并对各利用途径进行技术经济分析,提出了高含CO2天然气化工综合利用的建议。

High-carbon content natural gas is a kind of unconventional natural gas,which is not easy to be used directly due to its high content of carbon dioxide. However this high carbon dioxide makes up a lack of carbon of conventional natural gas, in particular, it is consistent with the requirements of adding carbon in the process of transformation of natural gas to propylene, so to fully make use of carbon dioxide and this type of natural gas re- sources. Stemming from this viewpoint, this paper analyzed the way of comprehensive chemically utilization of high-carbon content natural gas, along with the proposal of comprehensive utilization chemically of high-carbon natural gas.
