Hydrogen (H) and oxygen (O.) are reacted in a fuel cell to produce energy. The product...
In a hydrogen fuel cell, oxygen and hydrogen are combincd to produce water and a small potential differ- ence. The steps of the chemical reaction are: at-electrode: at + electrode: H2 + 20H-→ 2H2O + 2e-; O2 + H2O + 2e-→ 2OH-, Use the table of chemical values to calculate a) the work that can be produced from this fuel cell, b) the 'waste' heat produced during standard operation, c) the voltage of the cell, and d) the minimum voltage...
Propane is catalytically dehydrogenated to produce propylene by passing it over a granuar solid catalyst. In parallel with the main gas-phase reaction of propane dehydrogenation, side reaction to methane and carbon occurs: C,H,C,H +H A single-pass conversion of propane of 80%Is achieved in the reactor. Out of the propane reacting, 20% reacts according to the side reaction. The reactor effluent gases undergo a two-stage separation. In the first stage all hydrogen and 90% of the methane is separated, in the...
