    Oxidative Desulfurization of Gasoline by Ionic Liquids Coupled with Extraction by Organic Solvents
    摘要:
    In this work, desulfurization of real fluidized catalytic cracking (FCC) gasoline was investigated in dual steps; first in oxidative desulfurization (ODS) using imidazolium and pyrrolidonium based Bronsted acidic ionic liquids (ILs) as solvent and catalyst and hydrogen peroxide as oxidant. In second step, extractive desulfurization took place using organic solvents of furfural, furfural alcohol and ethylene glycol. Variety of factors such as temperature, time, mass ratio of oil/ILs and regeneration and recycling of ILs, multiple-step desulfurization of ILs and organic solvents and solvent/oil ratio were also investigated. The S-content was significantly decreased to ca. 18 ppm from initial S-content of 260 ppm with a total S-removal of ca. 95% in one-step ODS using pyrrolidonium based ILs coupled with five-step extraction desulfurization (EDS) using furfural alcohol as extractant. This work shows that oxidative desulfurization using ionic liquids coupled with extractive desulfurization using organic solvents is a potential method to produce clean gasoline.

    摘要:
    通过使用1-(4-磺酸)丁基-3-甲基咪唑硫酸氢盐(IL-1)作为有效催化剂将微晶纤维素(MCC)水解至一定程度(70%)。以相对较高的收率(分别为15%和7%)获得了有价值的化学品,例如5-羟甲基糠醛(HMF)和糠醛。有趣的是,在相同的条件下,MCC的转化率更高(84%),HMF和糠醛的产率更高(分别为34%和19%),证明了将FeCl 2作为催化剂引入IL-1可以进一步提高催化活性。在实验条件下,尽管也发现了少量的乙酰丙酸(LA)和总还原糖(TRS)。在没有催化剂(4%)或有Al 2的情况下,MCC的水解几乎不会进行,或显示出较低的效率O 3(7%),无机酸(≤65%)或其他几种离子液体(≤24%)作为催化剂。HPLC-MS分析表明,呋喃化合物的二聚体是主要副产物。通过质谱分析,可以确定气相产物的成分为甲烷,乙烷,CO,CO 2和H 2。提出了一种解释IL-1系统中FeCl 2高活性的

    parameters of the ILs were estimated. The trends of changing with temperature for the dynamic viscosity and the electrical conductivity were described by the Vogel–Fulcher–Tamman equation. The activation energies of dynamic viscosity and electrical conductivity were also calculated. Further, the structures and the energetics of the ILs ions were obtained through combining density functional theory calculations

    A quick and green process to prepare [Rmim]OH solutions is developed based on fast ion exchange between OH− and halide ions (halide = Cl− or Br−) in ethanol. Five ionic liquids were synthesized by neutralizing the obtained [Rmim]OH solution with acids to verify the feasibility of the whole process. The halogen content in the finally obtained ionic liquids and the experimental factors influencing the content are mainly discussed. Moreover, two other alcohols besides ethanol, propanol and iso-propanol, were further examined as solvents. The results show that this process, together with the alkylation and hydroxide anion route, is simple and efficient for preparing various ionic liquids, and that the process is a complementary synthetic route to existing strategies to prepare various ILs.
