    • In accordance with one example, a method for comparing data units is disclosed comprising generating a first digest representing a first data unit stored in a first memory. A first encoded value is generated based, at least in part, on the first digest and a predetermined value. A second digest representing a second data unit stored in a second memory different from the first memory, is generated. A second encoded value is derived based, at least in part, on the second digest and the predetermined value. It is determined whether the first data unit and the second data unit are the same based, at least in part, on the first digest, the first predetermined value, the first encoded value, and the second digest, by first processor. If the second data unit is not the same as the first data unit, the first data unit is stored in the second memory.
    • 根据一个示例,公开了一种用于比较数据单元的方法,包括生成表示存储在第一存储器中的第一数据单元的第一摘要。 至少部分地基于第一摘要和预定值生成第一编码值。 生成表示存储在与第一存储器不同的第二存储器中的第二数据单元的第二摘要。 至少部分地基于第二摘要和预定值导出第二编码值。 通过第一处理器,至少部分地基于第一摘要,第一预定值,第一编码值和第二摘要来确定第一数据单元和第二数据单元是否相同。 如果第二数据单元与第一数据单元不相同,则第一数据单元被存储在第二存储器中。

    • The present invention relates to a trifunctional catalyst used in catalytic cracking device in petroleum refining industry and a method for preparing the same. The trifunctional catalyst of the invention comprises absorbent, cerium dioxide and vanadium pentoxide acting as oxidative catalyst and cerium oxyfluoride acting as structural promoter. The oxidative catalyst and structural promoter are dispersed over the absorbent. The absorbent is spinel-based composite oxides having a general formula of MgAl2-xFexO4.yMgO, where the x is 0.01-0.5 and y is 0.2-1.2. In the trifunctional catalyst, the raw material for forming the chemical compound containing rare-earth cerium is hamartite powder. The method for preparing the trifunctional catalyst of the invention is shown as follows: the components relating to the preparation of the finished product are dissolved or dispersed into liquid materials; then the trifunctional catalyst is obtained after the mixing, drying and calcining of such liquid materials. The trifunctional catalyst of the invention is used for highly efficient absorption and desorption of sulfoxides contained in the catalytic cracking flue gas regenerated in the process of petroleum refining, the combustion promoting of carbon monoxide and the reduction of nitrogen oxides. Furthermore, the method for preparing such trifunctional catalyst is featured for its lower cost.
    • 本发明涉及用于石油炼制工业的催化裂化装置的三官能催化剂及其制备方法。 本发明的三官能催化剂包括作为氧化催化剂的吸收剂,二氧化铈和五氧化二钒和作为结构促进剂的氟氧化铈。 氧化催化剂和结构促进剂分散在吸收剂上。 吸收剂是具有通式MgAl2-xFexO4yMgO的尖晶石复合氧化物,其中x为0.01-0.5,y为0.2-1.2。 在三官能催化剂中,用于形成含有稀土铈的化合物的原料是不分散的粉末。 制备本发明的三官能催化剂的方法如下:与成品的制备相关的组分溶解或分散在液体材料中; 然后在这种液体材料的混合,干燥和煅烧之后获得三官能催化剂。 本发明的三官能催化剂用于石油精炼过程中再生的催化裂化烟道气中所含的亚砜的高效吸收和解吸,一氧化碳的燃烧促进和氮氧化物的还原。 此外,制备这种三官能催化剂的方法的特征在于其较低的成本。
