热化学法分解水制氢

Thermochemical Generation of Hydrogen from Water

本文提出了一种以Ｃｒ＿２Ｏ＿３及强碱为循环介质的二段闭路循环分解水制氢的新方法，通过热力学分析证明了此循环的热力学可行性，用正交试验探讨了反应条件对目的产物产率的影响。对主反应进行了动力学试验，获得了该反应的动力学方程。为进一步开发此循环打下了基础。

Anew process of a two-step close-cycle decomposition of water to produce hydrogenemploying alkali and Cr2O3 as cycling substances is proposed in this paper,Thermodynamic calculationshows that the cycle is thermodynamically possible. Experiments arranged according to orthographic designwere conducted to test the influence of reaction conditions on the yield of the product.Kinetic experimentIor the main reaction was also done and a kinetic equation was obtained.All these results provide afundamental for further development of the cycle.
