Diesel desulfurization came out a new technology! Recently, Chinese scientists have developed a new type of catalyst, which can produce the clean diesel with sulfur content controlled in the national V standard under the mild operating conditions on the basis of existing production processes and equipment. Currently, the catalyst was successful industrial trial run on 200,000 tons / year of diesel hydrogenation unit. According to the developers, the catalyst can be used in straight-run diesel fuel, straight-run diesel and diesel hybrid diesel catalytic and catalytic diesel ultra-deep desulfurization, thus to meet the national V, as well as indicators of future sulfur diesel requirements of the national VI.

 

Haze is the focus of ecological environment Thirteen Five-Year period, while motor vehicle exhaust emission is one of the major causes of haze. China has promulgated the legislation of enforcing to reduce the sulfur content in the fuel, and will carry out the State V diesel standard of a sulfur content of less than 10mg / kg before the end of this year. However, the most economic and easy way of diesel quality upgrading is to develop a high efficient hydrodesulfurization catalyst, to cut the sulfur pollution control from the source.

 

Of course, when the high sulfur content of the oil has been flowed into the market, we need to have the appropriate means to manage it. As we all know, the catalyst and non-precious metal catalyst which can be used in frequency combustion conditions have been developed for some time -- tungsten trioxide SCR desulfurization catalyst; with its active surface, it has catalytic oxidation can promote the direct reaction of sulfur dioxide, accelerate the dissolution of calcium carbonate, promote calcium sulfite rapidly oxidized to calcium sulfate, strengthen the precipitation of calcium sulfate, lower the ratio of liquid and gas, reduce the ratio of calcium and sulfur, reduce the evaporation of water. Thus, to maximize purify the sulfur dioxide and other harmful gases in the exhaust gas. Furthermore, since the tungsten trioxide catalyst can improve the properties of anti-vulcanization, anti-drug, anti-sintering ect., and thus to enhance the catalytic activity, improve the desulfurization efficiency, which makes it widely used in desulfurization catalyst.
