含硫气体的处理方法及用于该方法的加氢催化剂
摘要：
本发明涉及一种含硫气体的处理方法和用于该方法的加氢催化剂，所述处理方法包括将含硫气体引入硫磺回收装置尾气加氢单元，用本发明的加氢催化剂进行处理，加氢尾气经溶剂吸收，然后再生，再生的硫化氢返回Claus单元回收硫磺，净化尾气经焚烧炉焚烧后达标排放。所述含硫气体含二氧化硫0%~6%，氧气0%~3%，以体积计；温度为100～200℃。本发明的加氢催化剂，以占催化剂的重量百分数计，活性组分氧化镍含量为0.5～3%，活性组分氧化钴为1%～4%，活性组分氧化钼或氧化钨为8%～20.0%，脱氧助剂为1%～5%，TiO2为10%～40%，其余为γ－Al2O3。
摘要（英）：

Provided are a method for treating a sulfur-containing gas and a hydrogenation catalyst used in the method. The treatment method comprises introducing a sulfur-containing gas into a tail gas hydrogenation apparatus of a sulfur recovery unit, treating in the presence of the hydrogenation catalyst, absorbing a hydrogenated tail gas with a solvent, regenerating, and returning the regenerated hydrogen sulfide to a Clause apparatus for recovery of sulfur, incinerating the cleaned tail gas in an incinerator, and discharging in compliance with the standard. The sulfur-containing gas contains 0%-6% of sulfur dioxide and 0%-3% of oxygen, by volume; and the temperature is 100-200 DEG C. In the hydrogenation catalyst, based on the weight of the catalyst, the content of an active ingredient nickel oxide is 0.5%-3%, the content of an active ingredient cobalt oxide is 1%-4%, the content of an active ingredient alumina or tungsten oxide is 8%-20.0%, the content of a deoxygenation additive is 1%-5%, the content of TiO2 is 10%-40%, and the balance is gamma-Al2O3.
