Pressure swing adsorption (PSA) is an excellent way for separation and purification of gas mixtures. In this work, a process that separates hydrogen from mixtures with natural gas transported in the natural gas grid is present. The aim is to make a simulation and optimization of PSA for the hydrogen separation. The results show that Box-Behnken design provides sufficient data to fit the quadratic models for hydrogen production. And the target function is optimized by Minitab response optimiser. It is calculated that the optimised conditions are that temperature is 34°C, height ratio of activated carbon and zeolite layer is 1.73, and adsorption time is 382 s, the maximum hydrogen mole fraction is 0.8018.
