New chemical heat pump and hydrogen transportation systems with efficient use of catalytic hydrogenation/dehydrogenation reaction couples of organic compounds have been proposed.A cycle, composed of the exothermic catalytic hydrogenation of acetone in the gas phase, the fractional condensation of 2-propanol by cooling and the endothermic catalytic dehydrogenation of 2-propanol in the liquid phase, makes it possible to upgrade the low-quality heat of 80 ゜C to 200゜C with the expense of heat removal at 30 ゜C, being well evaluated for utilizing the geothermal waste water. Spherical nickel fine particles (ca. 20 nm <PHI> ) were proved to exhibit high activity and selectivity with long life for these reactions. The suspended catalyst gave hydrogen and acetone from 2-propanol, under refluxing even from the equimolar mixture with acetone (b.p. 64 ゜C). The surface modification with noble metals promoted the dehydrogenation activity. When supported on the porous active carbon, the same catalyst was active for acetone hydrogenation at high temperature range.The suspended nickel fine-particle catalyst, active as well for cyclohexane and methylcyclohexane dehydrogenation to yield benzene and toluene, respectively, affords a safety hydrogen transportation system, operated by low-quality heat.

本文提出了一种利用有机化合物催化加氢/脱氢反应对的新型化学热泵和氢气输送系统，该系统由丙酮在气相中的放热催化加氢、异丙醇在液相中的冷却分馏冷凝和异丙醇在液相中的吸热催化脱氢组成一个循环，使80 ℃ ~ 200 ℃的低品位热能升级成为可能，但需要在30 ℃时取热，对地热废水的利用有很好的评价。球形镍细颗粒（约20 nm<PHI>）具有较高的活性和选择性，反应寿命长。悬浮的催化剂从2-丙醇中产生氢气和丙酮，甚至从与丙酮的等摩尔混合物（沸点64 ℃）中产生氢气和丙酮。贵金属表面改性提高了催化剂的脱氢活性。负载在多孔活性炭上的催化剂对丙酮的高温加氢反应具有良好的催化活性，而悬浮镍催化剂对环己烷和甲基环己烷的脱氢反应也具有良好的催化活性，可以提供一个安全的低品位热氢输送系统。
