Abstract: QMS-01 adsorbent for removing methyl ethyl ketone and sec-butyl alcohol from hydrogen were developed and used for the purification of hydrogen in tail gas from methyl ethyl ketone unit. The commercial application results showed that using QMS-01 adsorbent, under appropriate conditions of tail gas space velocity in the range of 90-100 h－1, reaction pressure in the range of 2.4-3.0 MPa and reaction temperature in the range of 5-10 ℃, the mass fraction of methyl ethyl ketone and sec-butyl alcohol in the tail gas could be both less than 1 μg/g. The purified hydrogen could well meet the requirements of hydrogen for hydrogenation processes, and the adsorbent could be regenerated having a service life of about 3-5 years.

Key words: adsorbent, hydrogen, methtyl ethyl ketone, sec-butyl alcohol, regeneration
