A thermochemical hydrogen production process named UT-3 was proposed in combination with solar energy.Some amounts of water steam were produced from a solar collector at 800ﾟC,and then introduced directly into four reactors which were heated adiabatically. This method using adiabatic reactors showed a great possibility for improving thermal efficiency over 50% in comparison with conventional type of reactors heated from outside reactor walls.It was found that the bypass of a certain amount of water steam is needed to obtain good conversion of a reaction from consideration of its reaction equilibrium. In addition to solar heat, the possibility for utilizing discharged heat of coal-fired power stations and blast furnaces was studied, and the result will be presented at 11th World Hydrogen Energy Congress to be held in Argentine. The publication of a book about hydrogen energy written by E.Bligen and K.Yoshida is also in progress.

提出了一种与太阳能相结合的热化学制氢工艺UT-3，该工艺利用太阳能集热器在800 ℃下产生一定量的水蒸汽，然后将水蒸汽直接引入四个反应器中，并对反应器进行恒温加热。与传统的反应器壁外加热相比，绝热反应器的热效率可提高50%以上，但从反应平衡的角度考虑，为获得良好的反应转化率，需要一定量的水蒸汽旁路。除太阳能外，还研究了利用燃煤发电站和高炉排出的热量的可能性，并将在阿根廷举行的第11届世界氢能大会上公布结果。由E.Bligen和K.Yoshida撰写的一本关于氢能的书的出版也在进行中。
