Abstract

The invention relates to a process for biohydrogen cleaning from impurity gases.The process, according to the invention, includes biohydrogen treatment by the monoethanolamine solution absorption method, at the same time it is additionally used as an absorbent the copper-ammonium complex of formic acid, with the following content of components, mass %:The process is carried out at a temperature of 10…20°C and a pressure of 5…10 atm. After solution saturation with impurity gases is carried out its regeneration by heating to a temperature of 50…80°C and vacuum treatment at a residual pressure of 75…150 mm Hg.
