Catalytic Oxidative-Extractive Deep Desulfurization of Diesel Fuel by N-methyl-2-pyrrolidone-Based Protic Acidic Ionic Liquids (PAILs)
Inexpensive and low-viscosity Protic Acidic Ionic Liquids (PAILs) of N-metheyl-2-pyrrolidone formate, acetate, and propionate abbreviated as [Hnmp][HCOO], [Hnmp][CH3COO] and [Hnmp][CH3CH2COO] respectively, were prepared and characterized by FT-IR and H-NMR. Deep oxidative and extractive desulfurization of a simulated oil and a real diesel containing 1000 ppm...
متن کاملDeep desulfurization of diesel by adsorption over Ni/ZSM-5
Introduction Environmental restriction regarding the quality of transportation fuels and the emissions from them are the most important issues. Because of more stringent regulations and fuel specifications regarding development of better method for deep-desulfurization of fuels are important. There has been recent interest in developing adsorbents for selective desulfurisation by adsorption. Me...
متن کاملDeep Desulfurization of Transportation Fuels with Nanoreactions
Burning sulphur-laden transportation fuels results in misty and fuggy air of large cities. The combustion products of sulphur-laden fuels poison the exhaust conversion catalyst and invalidate the catalyst box. As results, the vehicle emission gets worse and worse no matter how advanced the auto technology is. Some sulphur compounds converted to sulphates after combustion and emitted into the at...
متن کاملDeep Desulfurization of Fuel Diesels Using Alkyl Sulfate and Nitrate Containing Imidazolium as Ionic Liquids
1-ethyl-3-methylimidazolium ethyl sulfate [Etmim][EtSO4 ],1, 3-dimethylimidazolium methyl sulfate [Mmim][MeSO4 ] and 1-octyl-3-methylimidazolium nitrate [Omim][NO3 ] ionic liquids have been used in thermal oxidative desulfurization of model fuel oils consisting of 500 ppm solutions of benzothiophene (BT) and dibenzothiophene (DBT) in dodecane. The efficiency of sulfur removal from BT and DBT so...
متن کاملA Systematic Study on the Effect of Desilication of Clinoptilolite Zeolite on its Deep-Desulfurization Characteristics
Natural clinoptilolite zeolite (CLP) in its original or metal ion- exchanged form (Ni2+) is a weak adsorbent for relatively large thiophene derivative molecules like benzothiophene (BT) and di-benzothiophene (DBT), due to its rather restricted micro-channel structure. A novelty of this work is that upon desilication treatments, it is possible to enhance the adsorption behavior of Ni2+-exchanged...
