Characterization and deacidification of acidic petroleum crude oil utilizing metal oxide catalyst supported on alumina and ammoniated polyethylene glycol solution

The presence of naphthenic acid (NA) in petroleum crude oil may cause serious corrosion problem for refinery processing equipment. In this work, an alternative method to remove NA is investigated based on the catalytic deacidification reaction to achieve the target of lowering the total acid number...
