Abstract
Official abstract text for this publication.
A catalyst component is described for reducing the total acid number of a refinery feedstock. A solid catalyst material that is pretreated with a caustic base solution form the catalyst component effective for contacting a refinery feedstock to reduce the total acid number.
First claim
Opening claim text (preview).
1 - 31 . (canceled) 32 . A catalyst component for reducing the total acid number of a refinery feedstock containing naphthenic acids comprising one or more solid catalyst materials selected from the group consisting of zinc aluminates and layered double hydroxides including magnesium/aluminum, wherein the solid catalyst material is pretreated with an aqueous caustic base prior to use. 33 . The catalyst component of claim 32 , wherein the aqueous caustic base comprises sodium hydroxide or potassium hydroxide. 34 . The catalyst component of claim 32 , wherein the colic catalyst material is pretreated in situ h contacting with the aqueous caustic base in a neutralization vessel used for contacting a refinery feedstock. 35 . The catalyst component of claim 32 , wherein the solid catalyst material is pretreated ex situ by contacting with the aqueous caustic base in a vessel separate from a neutralization vessel used for contacting a refinery feedstock. 36 . (canceled) 37 . (canceled) 38 . (canceled) 39 . (canceled) 40 . The catalyst component of claim 32 , wherein the solid catalyst comprises zinc aluminates. 41 . The catalyst component of claim 32 , wherein the solid catalyst comprises layered double hydroxides including magnesium/aluminum.
