Abstract: The invention comprises a method for reducing the amount of carboxylic acids in petroleum feeds comprising the steps of (a) adding to said petroleum feed a catalytic agent comprising an oil soluble or oil dispersible compound of a metal selected from the group consisting of Group VB, VIB, VIIB and VIII metals, wherein the amount of metal in said petroleum feed is at least about 5 wppm, (b) heating said petroleum feed with said catalytic agent in a reactor at a temperature of about 400 to about 800 °F (about 204.44 to about 426.67 °C), under a hydrogen pressure of 15 psig to 1000 psig (204.75 to 6996.33 kPa), and (c) sweeping the reactor containing said petroleum feed and said catalytic agent with hydrogen-containing gas at a rate sufficient to maintain the combined water and carbon dioxide partial pressure below about 50 psia (about 344.75 kPa).

Abstract: The present invention is a process for decreasing the acidity of a starting acidic crude oil by contacting an acidic crude with an effective excess of ammonia dissolved in said crude to form an ammonia-continuous oil discontinuous phase at a temperature and conditions sufficient to form the corresponding amide of the naphthenic acids. The process is useful in the processing of acidic crudes.

Abstract: The present invention is a process to remove a major portion of metals and coke precursors from a hydrocarbon stream. The steps of the process include contacting the feedstream with a hydrocarbon insoluble adsorbent, recovering the oil which does not adsorb and removing the metals and coke precursors from the adsorbent.
