About Moles per hour

The mole per hour (mol/h) equals 1/3600 mol/s ≈ 2.778×10⁻⁴ mol/s, practical for pilot-plant flow chemistry, laboratory gas manifold flow, and hydrogen production by small electrolysers. A 1 kW alkaline electrolyser at 100% Faradaic efficiency produces ≈18 mol H₂/h; bench-scale packed-bed reactors handle feed rates in mol/h. 1 mol/h ≈ 2.778×10⁻⁴ mol/s ≈ 0.002205 lb-mol/h.

About Moles per second

The mole per second (mol/s) is the SI coherent derived unit of molar flow rate, numerically equal to the katal (kat) for catalytic activity contexts. Industrial ammonia synthesis (Haber-Bosch) produces ≈50 mol/s of NH₃ per tonne/h output; a large turbine combustion chamber burns natural gas at ≈500 mol/s of CH₄. It is the reference unit in process simulation mass balances. 1 mol/s = 3 600 mol/h = 60 mol/min.
