<p>PURPOSE:To enhance the removal efficiency of carbonyl sulfide by controlling the copper content, pore radius, pore volume and specific area of the adsorbent of carbonyl sulfide in a fluid to specific ranges. CONSTITUTION:The adsorbent of carbonyl sulfide in a fluid has a carrier such as silica or alumina of which the volume of pores having a pore radius of 40-300Angstrom is 0.12ml/g or more and the specific surface area is 100m<2>/g or more. The copper content of this adsorbent is pref. 30-55wt.%. When the adsorbent having copper oxide supported on its carrier is brought into contact with a fluid containing carbonyl sulfide, carbonyl sulfide in the fluid is removed efficiently and inexpensively.</p> |
