The oxidation-extraction desulfurization of Saudi Arabian crudes was conducted with hydrogen peroxide-acetic acid oxidation system. The selection of extractant, the optimization of oxidation-extraction conditions, and the exploration of desulfurization mechanism were studied. As DMF was used as the extractant, the optimal desulfurization rate of 35.11 % and oil recovery of 95 % were obtained at...
A novel AgO/ZnO/HY-zeolite bimetallic nanocatalyst was designed and synthesized by an impregnation method. The purpose of this to remove dibenzothiophene as the primary sulfur content from a model light gasoil in catalytic oxidative desulfurization (ODS) process. characteristics were determined Fourier transform IR spectroscopy, Brunauer-Emmett-Teller analysis, scanning electron microscopy, X-r...
The paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. This experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orth...
Sulfur (S) and nitrogen (N) are elements naturally found in petroleum-based fuels. S- N-based compounds liquid fuels associated with a series of health environmental issues. Thus, legislation has become stricter worldwide regarding their content related emissions. Traditional treatment systems (namely hydrodesulfurization hydrodenitrogenation) fail to achieve the desired levels S N contents wit...
