ABSTRACT:
A supported metal chelate catalyst, and a method of preparing said catalyst is disclosed. The catalyst is particularly useful in the treatment of a sour petroleum distillate or fraction to remove mercaptans contained therein. In preparing the catalyst, a solid adsorptive support is contacted with a solution of a metal chelate and with a substituted ammonium compound, and thereafter heated.
In one embodiment, the metal chelate, cobalt phthalocyanine disulfonate, is contacted with the adsorptive support, activated charcoal, contacted with the substituted ammonium compound, dimethylbenzylalkylammonium chloride, and then raised to a temperature of 120.degree. C.
