Beschreibung
Zusammenfassung:	The invention discloses a preparation method of an adsorbent capable of removing hydrogen sulphide, carbonyl sulphide and carbon disulphide at the same time and belongs to the technical field of air pollution control. According to the preparation method of the adsorbent capable of removing hydrogen sulphide, carbonyl sulphide and carbon disulphide at the same time, walnut shells are treated, and the obtained biomass activated carbon adsorbent can remove hydrogen sulphide, carbonyl sulphide and carbon disulphide at the same time. The adsorbed prepared by adopting the preparation method disclosed by the invention is rich in pore structures, has a good effect of removing hydrogen sulphide, carbonyl sulphide and carbon disulphide, is more applicable to removal of mixed gas of hydrogen sulphide, carbonyl sulphide and carbon disulphide and is specific. The preparation method of the adsorbent capable of removing hydrogen sulphide, carbonyl sulphide and carbon disulphide at the same time is simple, easy to operate and low in cost.
