摘要：NOVELTY - Coalbed gas deoxidation involves preparing coalbed gas and water solution of iron sulfate which is oxidized in presence of catalyst. The catalyst is catalyst A or mixture of catalyst A and B, where catalyst A is iron metal and catalyst B is hydroxide of alkali metal, hydroxide of alkali earth metal, zinc hydroxide, ammonium hydroxide, ethylenediamine or 2-aminoethanol. USE - Method for deoxidation of coalbed gas (claimed). ADVANTAGE - The coalbed gas deoxidation method ensures to provide moderate reaction condition, large treatment load, short reaction time and high conversion rate, and enables to remove oxygen at normal temperature and pressure, and is safe, energy-saving and eco-friendly.
