ABSTRACT:
Disclosed are a method of preparing a catalytic composite useful in the treatment of sour mercaptan-containing petroleum distillates, and a method of using the catalytic composite in treating sour petroleum distillates. More specifically, the method of preparation comprises contacting an adsorptive support with a specified substituted ammonium compound, such as dimethylbenzylalkylammonium chloride drying the resulting composite, thereafter contacting the resulting composite with an alkali metal hydroxide and a metal chelate, such as a metal phthalocyanine the alkali metal hydroxide being in a weight ratio with the adsorptive support of from about 0.1:1 to about 1:1, and thereafter drying the resulting catalytic composite. A sour petroleum distillate can be treated with the catalytic composite by contacting the distillate at oxidation conditions with the catalytic composite.
