    Abstract: The composition based on a discharge from an oil refining plant after a desulfurization of heavy oils in the oil refining plant using a catalyst, comprising: 80% or less of vanadium; 80% or less of molybdenum; 20% or less of nickel; 30% or less of cobalt; 99% or less of alumina; and a trace of the impurities, which is catalytically active to purify the exhaust of diesel vehicles. A filter or a washcoat made of the discharged catalyst composition alone or in combination with ordinary filtering materials or ordinary washcoat materials can be very useful for purification of smoke. In addition, a catalyst in which at least one metal of the platinum group is uniformly impregnated on the filter is quite superior to conventional ones employing alumina or titania as a washcoat in stability to both high temperature and sulfur trioxide.

    Abstract translation: 基于使用催化剂在炼油厂中重油脱硫后的来自炼油厂的排出物的组成,其包含:80%以下的钒; 80%以下的钼; 20%以下的镍; 30%以下的钴; 99%以下的氧化铝; 以及痕量的杂质,其具有催化活性以净化柴油车辆的排气。 由排出的催化剂组合物单独或与普通过滤材料或普通修补基面涂料组合的过滤器或修补基面涂层可以非常适用于净化烟雾。 此外,将铂族金属的至少一种金属均匀地浸渍在过滤器上的催化剂与使用氧化铝或二氧化钛作为修补基面涂层在高温和三氧化硫稳定性方面的常规催化剂相当优越。
