Abstract
Disclosed is a method of preparing a catalytic composite useful in the treatment of sour mercaptan-containing petroleum distillates. More specifically, the method of preparation comprises contacting an adsorptive support with a substituted ammonium hydroxide, 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.
Claims12
A method of manufacture of a catalytic composite which comprises contacting an adsorptive support with a substituted ammonium compound represented by the structural formula:
- ##STR3## wherein 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 and R' is a substantially straight-chain alkyl radical containing from about 5 to about 20 carbon atoms, drying the resulting composite, thereafter contacting the resulting composite with a metal chelate and with an alkali metal hydroxide, said alkali metal hydroxide being in a weight ratio with said adsorptive support from about 0.1:1 to about 1:1, and thereafter drying the resulting catalytic composite.
