FIELD: chemistry.
SUBSTANCE: pure hydrogen is isolated from hydrogen-methane mixture at absorption stage at pressure 0.5-2.0 MPa. At desorption stage pressure is reduced to 0.1 MPa and unconditioned hydrogen, which is returned to adsorber input, is isolated, and then to complete desorption stage pressure is reduced to the lower level 0.1-0.005 MPa and fraction, mainly containing methane, which is returned to methane pyrolysis stage, is isolated.
EFFECT: invention makes it possible to separate methane-hydrogen mixture in efficient way and obtain additional amount of hydrogen.
