| Research Abstract |
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.
