绿色甲醇制备及其在内燃机上的应用

Green methanol production and its application oninternal combustion engine

综述了绿色甲醇理化指标、材料兼容性特点,对比了“生物质气化”和“液态阳光”两种绿色甲醇制备工艺优缺点、应用规模和技术瓶颈,分析了绿色甲醇在内燃机上应用的研究和应用现状。证明了利用可再生电力及工业排放CO_(2)合成液态阳光甲醇,能够解决可再生电力波动性与间歇性问题,实现电的“液态”存储,以及内燃机零碳排放。“坚持因地制宜、积极稳妥、安全可控,在具备应用条件的地区发展甲醇汽车”是发展方向。

The physicochemical indexes and material compatibility characteristics of green methanol are summarized. The advantages and disadvantages, application scale and technical bottlenecks of two green methanol preparation processes, namely biomass gasification and liquid sunlight, are compared. The research and application status of green methanol in internal combustion engines are analyzed. It is proved that the synthesis of liquid solar methanol from renewable electricity and industrial CO_(2) emissions can solve the volatility and intermittent problems of renewable electricity, realize the liquid storage of electricity, and achieve zero carbon emissions from internal combustion engines. The development direction is to adhere to local conditions, be active, stable, safe and controllable, and develop methanol vehicles in regions with application conditions.
