基于废气动能收集系统的自驱动碳氮联合固定实现尿素合成的研究

本项目以工业废气为应用对象，从能源和环境两个角度出发，围绕如何将残余机械能高效转化为电能和减少温室气体排放两个核心问题，逐步开展研究。拟通过构建一个完整的自驱动合成尿素系统，实现废气中残余动能利用的同时，在环境条件下固定其中的二氧化碳和氮气并最终获取尿素。本项目将探索气体动能到转动动能再到电能的能量转化规律，建立各级能量转换效率模型，并根据碳氮联合固定中的反应，探索相应的高效能量管理电路，解决其中的能量匹配利用问题。此外，将深入研究放电固氮合成氨的反应机理和提高转化效率的方法，并探索制备适用于二氧化碳和氨合成尿素的高效催化体系。本项目通过构建自驱动合成系统，为能源再利用和降低温室气体排放提供了一条新的思路。此外，环境条件下高价值产物—尿素的获得进一步提升了该方法的应用潜力。

This project focuses on the industrial exhaust gas as the application object, and will gradually carry out research on the two core issues of how to efficiently convert residual mechanical energy into electric energy and reduce greenhouse gas emissions, from the perspectives of energy and environment. It is proposed to build an integral self-powered urea synthesis system to realize the reuse of residual kinetic energy in the exhaust gas and the fixation of carbon dioxide and nitrogen in it, and finally obtain the product of urea at ambient conditions. This project will explore the law of energy conversion from gas kinetic energy to rotational kinetic energy and then to electric energy, establish the energy conversion efficiency model at all levels, and explore the corresponding efficient energy management circuit according to the reactions in the combined fixation of carbon dioxide and nitrogen to solve the problem of energy matching and utilization. In addition, the reaction mechanism of ammonia synthesis by nitrogen discharge and the methods to improve the conversion efficiency will be studied in depth, and the preparation of an efficient catalytic system suitable for urea synthesis from carbon dioxide and ammonia will be explored. This project provides a new solution for energy reuse and greenhouse gas emission reduction through the construction of a self-powered synthetic system. In addition, the application potential of this method is further enhanced due to the acquisition of high value product of urea.
