In this study, a Cu–Fe–Ce composite metal oxide adsorbent was synthesized by chemical precipitation method to simultaneously remove H₂S and PH₃. The effects of reaction temperature, oxygen content, gas inlet concentration and gas hourly space velocity (GSHV) were studied. The DRIFTS results showed that excessive oxygen and high reaction temperature lead to excessive conversion of H₂S, which competed with adsorption–oxidation of PH₃, and it was not conducive to simultaneous removal of H₂S and PH₃, and it was found that high concentration of H₂S was more likely to cause deactivation of the adsorbent than PH₃. GHSV affected the contact time between the adsorbent and the gas and affected the removal effect. The BET results showed that a larger specific surface area was more conducive to gas adsorption, and thus had a better removal effect. The XPS results showed that the deactivation of the adsorbent was due to the formation of sulfur-containing and phosphorus-containing substances.

在这项研究中，通过化学沉淀法合成了Cu-Fe-Ce复合金属氧化物吸附剂，以同时去除H ₂ S和PH ₃。研究了反应温度，氧气含量，进气浓度和气时空速（GSHV）的影响。DRIFTS结果表明，过量的氧气和较高的反应温度会导致H ₂ S的过度转化，这与PH _3的吸附-氧化竞争，并且不利于同时去除H ₂ S和PH ₃，发现与PH ₃相比，高浓度的H ₂ S更有可能导致吸附剂失活。GHSV影响吸附剂与气体之间的接触时间并影响去除效果。BET结果表明，较大的比表面积更有利于气体吸附，因此具有较好的去除效果。XPS结果表明，吸附剂的失活是由于形成了含硫和含磷的物质。
