提出了一种新的热化学分解循环。研究了循环中各主要化学反应的适宜条件，并从热力学计算出了循环中的能量流动过程；用ＴＧ法研究了循环中多相反应的动力学问题，实验和理论证明了该循环具有很大的节能优势。 A new thermochemical decomposition cycle was proposed. The suitable conditions of the major chemical reactions in the cycle were studied, and the energy flow in the cycle was calculated from the thermodynamics. The kinetic problem of the multiphase reaction in the cycle was studied by the TG method. The experiment and theory proved that the cycle has a large The energy saving advantage.
