在这项工作中提出了一种新的工艺流程,从天然气中共同生产氢气和甲酸,而不排放任何二氧化碳。这是通过采用涉及商业上可获得的技术的反应簇来实现的,所述商业上可获得的技术例如燃烧、干重整、水煤气变换反应、变压吸附和经由甲酸甲酯水解的甲酸生产。热力学和能量自给自足分析施加操作限制的建议的过程中,开发一个可行的流程图。热电集成分析表明,热机和热泵子网络是足以满足流程的能量需求,而不违反能源自给的约束。运行成本分析显示,当系统的运行点被选择为最大化氢气产量时,收入成本比为8.8。
Presented in this work is a novel process flowsheet that co-produces hydrogen and formic acid from natural gas, without emitting any carbon dioxide. This is achieved by employing a reaction cluster that involves commercially available technologies, such as combustion, dry reforming, water-gas shift reaction, pressure-swing adsorption, and formic acid production via methyl formate hydrolysis. Thermodynamic and energetic self-sufficiency analysis imposes operating limits on the proposed process, within which a feasible flowsheet is developed. Heat and power integration analysis reveals that heat engine and heat pump subnetworks are sufficient to meet the flowsheet's energy requirements without violating energetic self-sufficiency constraints. Operating cost analysis reveals a revenue to cost ratio of 8.8, when the system's operating point is chosen to maximize hydrogen production.
