10 Claims

1. A heterogeneous desulfurization catalyst, comprising:

a solid catalyst comprising:

a support comprising Al₂O₃in 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,

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.
