Abstract
Disclosed are a catalytic composite, and 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 a molecular sieve support with a specified substituted ammonium compound, drying the resulting composite, thereafter contacting the resulting composite with an alkali metal hydroxide and a metal chelate, 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.
