摘要

煤制甲醇生产过程伴随着大量二氧化碳排放，绿氢耦合煤化工技术可以有效降低煤化工过程碳排放，但其中存在的技术问题和经济效益未经有效评估。基于调研数据，构建了绿氢耦合煤制甲醇工艺二氧化碳排放的核算体系，并分析了绿氢耦合技术在低碳排放背景下的技术竞争力。结果表明，绿氢耦合煤制甲醇工艺通过再生能源制氢、制氧，可省去原有CO变换、空气分离工序。以某60 × 10

t/a煤制甲醇项目为例，采用传统煤制甲醇工艺二氧化碳排放量为205.94 × 10

t/a，采用绿氢耦合煤制甲醇工艺二氧化碳排放量为60.94 × 10

t/a，二氧化碳排放量相较减少了约70%。随着国家对新能源产业的大力支持，以及能源转型战略的快速推进，当绿电价格下降到0.15 CNY/(kW·h)，绿氢耦合煤制甲醇产品成本约为2883.33 CNY/t，与传统工艺产品成本相当。若未来电价持续走低并辅以碳税征收，绿氢耦合煤制甲醇工艺的经济优势将逐步体现。本研究可为“双碳”目标下煤化工行业实现净零碳排放提供参考。

Abstract

The coal-to-methanol production process is accompanied by significant carbon dioxide (CO

) emissions. Green hydrogen-coupled coal chemical technology can effectively reduce carbon emissions in coal chemical processes

yet the associated technical challenge

s and economic benefits have not been adequately assessed. Based on survey data

an accounting system for CO

emissions in the green hydrogen-coupled coal-to-methanol process was established and the technological competitiveness of green hydrogen coupling under the low-carbon emission context was analyzed. The results indicate that the green hydrogen-coupled coal-to-methanol process

utilizing renewable energy for hydrogen and oxygen production

eliminates the need for the original CO conversion and air separation steps. For a 60 × 10

t/a coal-to-methanol project

the CO

emissions of the traditional coal-to-methanol process amount to 205.94 × 10

t/a

whereas the green hydrogen-coupled process reduces emissions to 60.94 × 10

t/a

a reduction of approximately 70%. With strong national support for the renewable energy industry and rapid advancement of the energy transition strategy

when the price of green electricity decreases to 0.15 CNY/(kW·h)

the cost of green hydrogen-coupled coal-to-methanol production is approximately 2883.33 CNY/t

comparable to the cost of traditional processes. If electricity prices continue to decline and are accompanied by carbon tax implementation

the economic advantages of the green hydrogen-coupled coal-to-methanol process will gradually emerge. This study can provide a reference for achieving net-zero carbon emissions in the coal chemical industry under the “carbon peaking and carbon neutrality” goals.
