项目摘要

Water and CO_2 were easily reduced by using metal Fe and Ni under hydrothermal conditions and to form hydrocarbons. The activated hydrogen from water and the activated CO_2 on metal surface reacted each other and to form hydrocarbons. We confirmed the basic principle of above reactions. The produced alkane groups (gaseous phase) under neutral hydrothermal conditions showed this reaction proceed according to a Fisher-Tropseh reaction via CO formation. On acidic conditions, many carboxylic acids were detected in solution phase. When the magnetite powder was used instead of metals, ethanol was detected in solution phase. In final year (2002), the bench scale flow system autoclave for industrial scale treatment were developed and confirmed the possibility in use the research of non-equilibrium reaction. The batch type autoclave can be used for equilibrium reaction and fitted in the ideal basic research, however this flow system autoclave can be used in the natural analogue experiment (simulator of water flow underground) and the tube digester research for the practical industrial scale treatment. This non-equilibrium reaction in a typical complex system and the non-traditional science. In here, the lathe scrap of metallic iron was set in this tube reactor and the mixed flow of HCl solution and CO_2 gas were introduced in this heating tabs and the outlet sample from tube reactor was collect and determined the carboxylic compounds. In systematic research planning, firstly, the activated hydrogen and CO_2 are formed, and hydrocarbons were synthesized at second stage, and at next stage we discovered the selective formation of organic compounds by the control of hydrothermal conditions and at the last stage we could showed the possibility of large scale treatment by using this flow system autoclave.

在水热条件下使用金属Fe和Ni很容易减少水和CO_2并形成碳氢化合物。从水和金属表面上激活的CO_2激活的氢反应并形成碳氢化合物。我们确认了上述反应的基本原理。中性水热条件下产生的烷基基团（气态相）表明，根据CO形成的Fisher-Tropseh反应进行了这种反应。在酸性条件下，在溶液相中检测到许多羧酸。当使用磁铁矿粉代替金属时，在溶液相中检测到乙醇。在最后一年（2002年）中，开发了用于工业规模处理的基准流量系统高压釜，并确认了使用非平衡反应研究的可能性。批处理型高压灭菌器可用于平衡反应并在理想的基础研究中安装，但是该流量系统高压灭菌可用于自然模拟实验（地下水流的模拟器）和Tube Dipester Research进行实际工业规模处理。在典型的复合系统和非传统科学中的这种非平衡反应。在这里，在此管反应器中设置了金属铁的车床废料，并在此加热片中引入了HCl溶液的混合流，并将CO_2气体引入，并收集来自管反应器的出口样品并确定羧化合物。在系统研究计划中，首先形成了活化的氢和CO_2，并在第二阶段合成了碳氢化合物，在下一阶段，我们通过控制水热条件发现了有机化合物的选择性形成，在最后阶段，我们可以使用这种流动系统自动球使用大规模处理。
