目的 随着欧盟碳边境税的实施及国际航运公司大量生产绿色甲醇燃料船舶,未来全球对绿色甲醇的需求将急剧增加,因此,亟需探索绿色甲醇生产技术商业化运行的可行性。方法 通过对不同生物燃气制绿色甲醇技术路线的对比分析,构建了基于生物质厌氧和气化制生物燃气,结合绿电制氢,最终形成资源循环利用以生产绿色甲醇的模型。结果 该模型可输出绿色甲醇10×104 t/a、生物有机肥12×104 t/a、活性炭7 000 t/a,CO2总减排潜力达到80×104 t/a,纳入碳减排收益该模型可实现税后内部收益率超过8%的经济可行性。结论 经过理论参数分析构建的依托风、光绿电及生物燃气制绿色甲醇技术路线,可为国内生物质资源高值化利用项目开发及风光绿电消纳提供借鉴。 |

Objective The implementation of the EU CBAM policy and the large-scale production of green methanol fuel ships by international shipping companies will lead to a sharp increase in global demand for green methanol in the future. On this basis, it is necessary to research the feasibility of commercial operation for green methanol production. Methods The technologies for producing green methanol from biomass gas are analyzed comparatively. A resource-recycling green methanol production model based on the combination of hydrogen producted by green electricity and anaerobic/gasification gas producted by biomass is created. Results The model could output 100×103 tons of green methanol, 120×103 tons of bioorganic fertilizer and 7 000 tons of active carbon annually, and the total annual carbon dioxide emission reduction potential could reach 800×103 tons, and achieve an economically feasible for the post-tax internal rate of return exceeding 8% inclusion carbon reduction benefits. Conclusion After theoretical parameter analysis, the technology route for producing green methanol based on green electricity from the wind and solar energy and biomass gas will provide certain guiding for the high-value utilization of biomass resources and the consumption of the green electricity from the wind and solar energy in China. |
