TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The catalyst is heated by using at least one of sources comprising renewable energy resources (preferred) (e.g. solar concentrator), electrical heater and/or thermic fluid. The catalyst used is nanostructured with a size of 3-100 nm. Preferred Components: In the M/support type metal catalyst, M is present at 2-20 wt.%, and in the M1-M2/support type metal catalyst, M1 is present at 2-20 wt.% and M2 is present at 0.1-3 wt.%. The hydrogen evolution rate using M/support is 300-1000 mmol/gmet/minute, and using M1-M2/support is 10-70 mmol/gmet/minute. The conversion efficiency of the organic compound and hydrogen storage capacity is 20-99% and 1.44-6.1 wt.% respectively.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The dehydrogenation reactor used is microchannel reactor, pulse-spray reactor, continuous reactor or column reactor of cross section of rectangular, triangular, elliptical, circular or any irregular shape.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The hydrogenated liquid organic compound contains hydrogen in chemically bonded form, capable of storing hydrogen of 2-8 wt.% and 10-62 kg of hydrogen/m3 of volume, where the compounds are cyclohexane, methyl cyclohexane, decalin, 2-propanol or liquid pi conjugated form of organic compounds. EXAMPLE - Yttrium oxide was dried in oven at 80 degrees C for 2 hours. Platinum tetrachloride (0.02M, 21.11 ml) was taken for platinum (3 wt.%) loading over yttrium oxide, achieved by wet impregnation. The prepared catalyst (platinum/yttrium oxide) was dried in oven at 100 degrees C. The catalyst (3 wt.%) was used for carrying out dehydrogenation of methylcyclohexane using a specially designed spray-pulsed rector. A cylindrical reactor was used with an injection nozzle at the top of the reactor. The catalyst was placed at the center of the reactor with arrangement for heating and a temperature controller. The nozzle was placed in such a way to inject atomized spray of reactant over catalysts. The reactant was sprayed in a periodic manner after every 1 second. The injection frequency and injection pulse were with in terms of 0.3 Hz and 10 milliseconds respectively by a frequency regulator. The reaction was carried out in nitrogen atmosphere at a pressure of 1.2 atm. The hydrogen generated was monitored using gas chromatograph for product gas analysis. The conversion efficiency for methylcyclohexane over catalyst (3 wt.%) at 350 degrees C was 98.26% therefore hydrogen storage capacity of 6.1 wt.% and 60.92 kg/m3 on volume basis was obtained.
