METHOD OF APPARATUS FOR REMOVING GASEOUS ADMIXTURES FROM HYDROGEN STREAM

摘要

FIELD: purification of gases. SUBSTANCE: to remove from hydrogen stream carbon mono- and dioxides and moor difficultly removable admixtures mainly composed of nitrogen and methane, hydrogen stream is first brought in contact (at 5-50 C) with a material containing nickel and/or nickel compounds, wherein at least 1 wt % of total quantity of nickel is in reduced state, and then the stream yet containing nitrogen and methane is brought in contact with a gas-absorbing material at lower temperature. EFFECT: enhanced efficiency of process.
