Process for preparing solid cuprous halide sorbents

Claim 1

A PROCESS FOR PREPARING SOLID CUPROUS HALIDE SORBENTS WHICH COMPRISES: (A) DISSOLVING A CUPROUS HALIDE SALT CONTAINING NOT IN EXCESS OF 0.5 WT. PERCENT MOISTURE AND SELECTED FROM THE GROUP CONSISTING OF (1) CUPROUS CHLORIDE, (2) CUPROUS BROMIDE, AND (3) CUPROUS IODIDE IN A HYDROCARBON SOLVENT MIXTURE HAVING A BOILING RANGE OF FROM ABOUT 60 TO ABOUT 330*F., AND CONSISTING IN ITS ESSENTIAL COMPONENTS OF C4 TO C9 TYPE I TO TYPE IV MONOOLEFINS AND AT LEAST ONE LOW SOLUBILITY COMPONENT SELECTED FROMTHE GROUP CONSISTING OF (1) C6 TO C7 MONOCYCLIC AROMATIC, (2) C5 TO C7 CYCLIC MONOOLEFINS, AND (3) MIXTURES OF (1) AND (2), SAID ESSENTIAL COMPONENTS CONSTITUTING FROM 82 TO 100WT. PERCENT OF SAID SOLVENT MIXTURE WITH FROM 0 T/ 18 WT. PERCENT THEREOF BEING SELECTED FROM THE GROUP CONSISTING OF (1) POLYOLEFINS, (2) PARAFFINS, AND (3) MIXPONENTS APPROXIMATING 100 WT. PERCENT OF SAID HYDROCARBON SOLVENT MIXTURE, AT TEMPERATURES OF ABOUT -50 ABOUT 70*F.; (B) CONTACTING SAID CUPROUS HALIDE SOLUTION AT TEMPERATURES OF ABOUT -40 TO ABOUT 20*F. WITHA COMPLEX FORMING COMPOUND CAPABLE OF FORMING A STABLE COMPLEX WITH SAID CUPROUS HALIDE HAVING A MOL RATIO OF COPPER TRO COMPLEXING COMPOUND GREATER THAN 1:1 TO FORM A STABLE CUPROUS HALIDE COMPLEX WHICH IS AT LEAST PARTLY INSOLUBLE IN SAID HYDROCARBON SOLVENT MIXTURE; (C) RECOVERING SAID CUPROUS HALIDE COMPLEX AND (D) DESORBING SAID COMPLEX BY HEATING TO THEREBY PRODUCE AN ACTIVE CUPROUS HALIDE SORBENT.
