Десульфирование соединений нефти является одной из актуальных задач современной нефтяной промышленности в связи с ужесточающимися требованиями по содержанию серы топливе. Несмотря на успешное промышленное использование, процессы обессеривания требуют разработки новых эффективных подходов, одним которых может стать использование сверхкритических растворителей. В данной работе приводятся результа...

Novel 1-trifluoromethyl-4-quinolone derivatives (8a,b) were synthesized, and the antibacterial activity of each was evaluated. An oxidative desulfurization-fluorination reaction was employed to introduce a trifluoromethyl group at the N-1 position as a key step. Among the derivatives, 8a was found to exhibit antibacterial activity comparable to that of norfloxacin (1) against Staphylococcus aur...

Reaction of thiodiacetate anion (tda) with [Cu(TMEDA)(NO3)2] (TMEDA = N,N,N'N'-tetramethyl ethylene-diamine) in a stoichiometric ratio afforded the complex {[Cu(TMEDA)(tda)]·(H2TMEDA)(NO3)2·H2O} (1). When [Cu(TMEDA)(NO3)2] was added in excess, it yielded a μ-oxalato complex {[Cu2(TMEDA)2(μ-ox)(H2O)2](NO3)2·2CH3CN} (2). The reaction involves a facile room temperature desulfurization of the thiod...

Biodesulfurization (BDS) can be used as complementary technology to traditional hydrodesulfurization (HDS) process for sulfur reduction in fossil fuel. One of the mayor problems of BDS is the lower desulfurization yield obtained due to the low solubility of organosulfur compounds in water phase where microorganisms survive. In this work, the use of chemical surfactants largely increase the proc...

The objective of this research is to find an economically attractive alternative method for hydrodesulfurization of petroleum fractions and to select a suitable adsorbent for this process.Deep desulfurization of transportation fuels (gasoline, diesel, and jet fuels) is being mandated by governments and is also needed for future fuel cell applications. However, it is extremely difficult and ...

As an industrial solid waste, the discharge of a large amount red mud (RM) causes serious environmental problems; thus, proportion RM co-combustion has been proposed to solve consumption problem. In this paper, experiment with various proportions was conducted on 0.2 t/h circulating fluidized bed (CFB) boiler. Desulfurization performance, combustion characteristics, and ash deposition character...

Hierarchically porous Ti-SBA-2 with high framework Ti content (up to 5 wt%) was firstly synthesized by employing organic mesomorphous complexes of a cationic surfactant (CTAB) and an anionic polyelectrolyte (PAA) as templates. The material exhibited excellent performance in oxidative desulfurization of diesel fuel at low temperature (40 °C or 25 °C) due to the unique hierarchically porous struc...

10-Methylthioacridone, designated as acrithion, has been employed as an easily accessible chemodosimeter for the optical targeting of toxic Hg(2+) in buffered aqueous DMSO. The Hg(2+)-mediated desulfurization of the probe is translated into selective dual signaling of Hg(2+) by means of color bleaching and fluorescence amplification while several other metal ions, including potentially competin...
