Abstract
A two or particularly three-phase process, and corresponding apparatus, desulfurizes sour hydrocarbon gas, e.g., natural gas, generally better than known, using a fixed-bed, two-phase processes in terms of the amount of H2S scavenged and the breakthrough time of H2S. The three-phase process is effective in scavenging H2S at ambient temperature and pressure, using a copper salt catalyst impregnated on alumina or other generally inert support, which is regenerable.
Claims6
A heterogeneous desulfurization catalyst, comprising:
- a solid catalyst comprising:
- a support comprising Al2O3 in an amount of at least 95 wt. %, based upon total support weight, the support being inert to desulfurization at ambient conditions;
- copper (II) ions upon and impregnated within the support in an amount of at least 95 wt. %, based upon total catalytically active metals in the catalyst at the ambient conditions, and
- a liquid comprising at least 75 wt. % H2O, based upon total solvent weight, and at least one selected from the group consisting of ethylene glycol, methanol, ethanol, propanol, isopropanol and n-butanol,
- wherein the heterogeneous desulfurization catalyst is in the form of an aqueous suspension having a solid-liquid ratio, measured as solid catalyst mass per mass of liquid, in a range of from 0.01 to 1.5.
