柴油硫含量检测论文

Abstract Many large diesel vehicles and diesel fuel the main driving force, with power, and the advantages of cheap, is the largest of China's consumption of petroleum products. As environmental awareness increased, and on diesel products increasingly stringent quality requirements, for which China has developed new standards for 2000 diesel GB252-2000, for motor vehicle diesel sulfur content, color, sediment and other references Of a higher demand. This paper discusses the application of non-hydrogenation FS - Trap complex RFCC diesel refining process. Fushun Petrochemical Corporation of raw materials from the production of heavy oil catalytic cracking plant diesel (55%-doped vacuum residue), Jing Jing FS preparation for FS01 complexing agents and trapping agent. FS Act refined diesel RFCC higher yield of diesel oil, up to . Basic nitrogen removal rate of percent, the actual rate of glial lower, the total insoluble reduced to mg/100mL. After the catalytic cracking of refined diesel fuel does not contain water-soluble acid-base; mercaptan sulfur content by μg • g-1 down to 0μg • g-1; refined diesel colority RFCC , oxidative stability for the total insoluble mg/100mL, to meet national quality standards GB252-2000 requirements. In this paper, the design of the production capacity of 200,000 tons of non-RFCC diesel hydrotreating unit, as well as the process principle, major equipment selection, size of the calculation and description of technical parameters. The experimental results show that: the technology is most cost far less than the hydrogenation is the hydrogenation capacity of non-diesel refinery to upgrade the quality of an effective way.打字好辛苦。。。。。

成品柴油硫含量不合格的原因目前降低柴油中含硫量的方法主要有加氢脱硫和非加氢脱硫。加氢脱硫技术要求高温高压氢环境以及贵金属催化剂等苛刻条件。费用昂贵。吸附脱硫是新型方法，操作简单，费用少。该技术以活性炭为载体，CuO,ZnO和硝酸为改性剂，采用等体积浸渍法制备脱硫剂，采用静态吸附法和固定床动态吸附法对脱硫剂的吸附性能进行评价。参考资料：中国海洋大学硕士论文

不使用仪器是测不出来的。因为燃油中的含硫化合物种类很多，需要把它们都分解后才能测定。仪器最简单最便宜的是燃灯法，但操作复杂，需要滴定；微库仑法简单一些，但仪器贵得五六万一台；化学发光法（荧光法）最简单，但仪器得十几万一台。

abstractDiesel vehicles are many large internal combustion engines and the main force, with power and fuel prices cheaper in China, is the largest oil consumption of products. Along with the people environmental protection consciousness, the enhancement of diesel oil products' quality, therefore our new 2000 diesel GB252-2000, the standard of the sulfur diesel, chroma, sediment, etcA higher article mainly discusses the application of FS hydrogenation - complexation capture process refined oil catalytic cracking diesel oil. Raw material and fushun petrochemical companies from the production of catalytic cracking diesel (d), mix pure preparations for 55% of pure and FS01 complexometric capture. FS method after refining diesel fuel catalytic cracking diesel oil refining of high yield, can reach. Alkaline nitrogen removal rate, reduce tissue rate, total insoluble, reduce to mg / 100 ml. After the catalytic cracking diesel oil refining consists of water-soluble acid-base, Mercaptan from muon g, sulfur is 0-1 drop g. g. g. - 1, speeds, After the refined oil catalytic cracking diesel oil, the chroma of the oxidation stability total insoluble, for mg / 100 ml, satisfy GB252-2000 quality paper designs an annual capacity of 200,000 tons of RFCC diesel hydrotreating process equipment, as well as the principle of selection of equipment, the main technical parameters, calculation and size. Experimental results show that this technique processing costs far less hydrotreating, is the ability to ascend without hydrogenation of the quality of diesel oil refinery effective ways.

对于用翻译软件翻译的，楼主不要使用。看看翻成啥了！！！
