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.
Claims22
A method of preparing a supported metal chelate catalyst which comprises contacting a solid adsorptive support with a solution of a metal chelate and with a substituted ammonium compound represented by the structural formula ##STR2## where R is a hydrocarbon radical containing up to about 20 carbon atoms and selected from the group consisting of alkyl, cycloalkyl, aryl, alkaryl and aralkyl, R' is a substantially straight-chain alkyl radical containing from about 5 to about 20 carbon atoms, and X is an anion selected from the group consisting of halide, nitrate, nitrite, sulfate, phosphate, acetate, citrate, tartrate and hydroxide, and wherein said prepared composite is heated to a temperature below the temperature of decomposition of the metal chelate or the substituted ammonium compound.
