ComPlexation Process and kinetics equation of alkaline nitrogen removal in shale oils With LeWis
摘要
Abstract
This paper aimes to remove alkaline nitrogen compounds in shale oil.The research is fo-cused on investigating the denitrification effect of four kind Lewis acids(FeCl3, TiCl4, CuCl2and AlCl3);optimizing CuCl2denitrification process conditions via single factor and orthogonal experiments;and probing into the kinetics of Lewis acid complexing alkaline nitrogen.The optimized process condi-tions of CuCl2denitrification consist of the reaction temperature of 65 ℃; CuCl2dosage of 0.5 mol/kg shale oil;the solvent-to-shale oil volume ratio of 5;and the reaction time of 25 min,all of which contrib-ute to the denitrification rate of up to 87.7%.The analysis using the spectrum of FTIR and gas chroma-tography/mass spectrometry indicates the presence of derivatives of aromatic amines or pyridines,and a-mine nitrogen groups in the removed components by CuCl2.The analysis building on the kinetics of Lewis acid complexing alkaline nitrogen shows the conformity of both the concentrations of CuCl2and basic ni-trogen to the 0.5-order kinetics,with the total reaction rate being expressed in one-order kinetics model. The results show that CuCl2offers the best removal of alkaline nitrogen in shale oil; The research may provide a viable technical scheme and theoretical basis for the complexing denitrification of shale oil.关键词
