摘要：
Catalytic dehydrogenation of decalin (decahydronaphtalene), a promising material for hydrogen storage, has been investigated. The amount of hydrogen produced on a Pt (3 wt.%)/C catalyst has been studied as a function of pressure, temperature, and the substrate feed rate in a flow-type reactor. The maximum volume of the released hydrogen is achieved at atmospheric pressure, a temperature of 320 degrees C and a substrate LHSV of 1 h(-1). The dehydrogenation occurs mainly by conversion of cis-(97%) and partial conversion of trans-decalin (66%) with a selectivity of 97% to naphthalene. The amount of the released hydrogen corresponds to the decalin hydrogen capacity (5.5 wt. %). The obtained results are consistent with the calculated thermo-dynamic characteristics of the studied reaction.
