Deep desulfurization of transportation fuels is receiving increasing attention in theresearch community worldwide due to increasingly stringent regulations and fuelspecifications in many countries for environmental protection purpose. The traditionalhydrodesulfurization process (HDS) is highly efficient in removing thiols and sulfides, but itis less effective for thiophenes and thiophene derivatives. Ultra-deep desulfurization isbecoming even more formidable challenge for HDS with the decreasing lower sulfur in fuels.Therefore, non-hydrodesulfurization technique of liquid fuels has caused intensive concernsfor ultra-deep desulfurization. Recently, the adsorption desulfurization technique and catalyticoxidation-adsorption desulfurization technique have drawn much attention at home andabroad due to its mild reaction condition,low production cost and little environmentalpollutioz. This thesis focuses on the researches of application of activated carbon fiber inadsorption and oxidation-adsorption removal of thiophenic sulfur compounds from oils.Adding appropriate chemical reagents will play the role of catalytic oxidation [73], and these chemical reagents will also increase the active point of activation reaction, which is conducive to
the development of activated carbon pores.dxd carbon
Now at home and abroad the main research work is mainly the following aspects: a, additive in the functional mechanism of manufacturing activated carbon energy gao jun of China university of mining mechanism of additives in the manufacturing activated carbon made detail [4, pointed out that: the catalyst in the carbonization stage prompted carbon the destruction of the molecular structure of aromatic raw materials, to "structure" of disordering, provides a good initial activation reaction conditions, is an important factor to improve the activation of activated carbon pore. In the process of activation, potassium to strengthen the directionality of the pore, thereby reducing the unnecessary on ignition, and accelerated the process of pore forming,
And pore distribution is given priority to with microporous activated carbon; refractory in the catalyst to ash content of SiO2 and Al, 03, etc, into acid soluble potassium nepheline chemical compounds such as magnesium and calcium silicon stone is the key to improve pickling deliming rate factor b and additives on the activated carbon adsorption properties, pore structure and pore size distribution - adding different additives. The influence of the activated carbon: c, chemicals for coking products.suppliers of activated carbon
