| Abstract: | Caustic washing-catalytic oxidation was adopted to purify yellow phosphorus tail gas. The purification (efficiency) could be remarkably improved when the reaction temperature and oxygen volume fraction raised. When the yellow phosphorus tail gas was purified under optimum process conditions, i.e. reaction temperature 110 ℃ and oxygen volume fraction 1.5 %, the total phosphorus mass concentration was less than 10 mg/m~3, hydrogen (sulfide) mass concentration less than 10 mg/m~3 and hydrogen fluoride less than 5 mg/m~3, thus meeting the (requirement) on feedgas for producing C1 chemical (products.) Invalidated catalyst is apt to regenerate and the (catalyst′)s capability is fine after repeated regenerations. |
