Abstract: A sulfur-containing oil is initially preoxidized with an oxidant, such as, an organic peroxide, an organic hydroperoxide, air or an organic peracid in the presence of a Group IV-B, Group V-B or VI-B metal catalyst, water is then added to the preoxidized oil and desulfurization is carried out with sodium oxide, potassium oxide or calcium oxide catalyst on an alumina support. Water is added to the oil prior to desulfurization at a concentration ranging from 1 to 20 percent by weight.

Abstract translation: 在IV-B族，VB族或VI-B族金属催化剂的存在下，最初用含氧化剂如有机过氧化物，有机氢过氧化物，空气或有机过酸预氧化含硫油，然后将水 加入预氧化油中，用氧化铝，氧化钾或氧化钙催化剂在氧化铝载体上进行脱硫。 在脱硫之前以1至20重量％的浓度将水加入到油中。

Abstract: THE PIPELINE FLOW CHARACTERISTIC AND THE GEL STRENGTH OF WAXY CRUDES, IN PARTICULAR NORTH AFRICAN CRUDES, ARE IMPROVED BY CENTRIFUGING UNDER SPECIFIC CONDITION TO REMOVE AN OPTIMUM AMOUNT OF WAX. IN A MODIFICATION OF THE PROCESS, LESS THAN THE OPTIMUM OF WAX IS REMOVED AND A DEWAXING AID IS ADDED TO THE CRUDE PRIOR TO CENTRIFUGING OR TO THE DEWAXED CRUDE. THE REMOVED WAX CAN BE VISBROKEN OR THEMALLY CRACKED, AND THE RESULTING FLUID CAN BE ADDED TO THE DEWAXED OIL.

Abstract: THE INTRODUCTION OF A DEWAXING AID INTO WAXY CRUDES

FOLLOWED BY PREHEATING OF THE CRUDE AND THE ADDITIVE PRIOR TO DEWAXING INCREASES THE AMOUNT OF HEAVIER WAX REJECT STREAM AND THE FUEL OIL (OR 650*F. FRACTION) RECOVERED FROM THE DEWAXED CRUDE BY FRACTIONATION HAS A REDUCED POUR POINT. THE REDUCTION IN POUR POINTS RANGES FROM 10* TO 35*F.
