摘要
Abstract
The emission of high-sulfur fuel combustion will cause great damage to environment and seriously affect the living environment of human beings.It is very important to develop efficient hydrodesulfurization(HDS)catalysts.In this work,Phosphorus quantum dots and commercial red phosphorus were used for the first time to modify the unsupported catalyst(Raney nickel),and the influence of modification conditions(modification temperature,dosage,reaction temperature)on the performance of catalyst hydrodesulfurization(DBT)was systematically explored.The modified catalysts were characterized by BET,XRD,SEM,TEM,EDS and XPS,and their catalytic activity was evaluated for dibenzothiophene(DBT)hydrogenation.The results showed that the HDS performance of Rainey nickel modified with phosphorus quantum dots were greatly improved that could be attributed to the increased pore size of the modified catalyst and the strong interaction between phosphorus quantum dots and nickel.Large pore size was beneficial for the diffusion of DBT molecules,and the positively charged Niδ+ generated by the interaction with phosphorus quantum dots facilitates the adsorption of DBT,thereby improving the hydrodesulfurization performance of the catalyst.DBT conversion rate of 99.1%was achieved under optimal experimental conditions.关键词
