METHOD OF REMOVING HYDROGEN CYANIDE AND AMMONIA FROM SYNTHESIS GAS Russian patent published in 2013 - IPC C01B3/56 C10K1/32

Abstract RU 2475446 C2

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry. The method of removing HCN and NH₃ from synthesis gas involves the following steps: (a) bringing crude synthesis gas containing HCN into contact with a HCH-hydrolysing sorbent in the presence of water to obtain synthesis gas which contains NH₃, and (b) bringing the synthesis gas containing NH₃ into contact with an acidic cation-exchange resin in the presence of water to remove NH₃. Purified synthesis gas is obtained as a result.

EFFECT: invention simplifies the method and reduces capital costs.
