The economy of desulfurization system is of great significance for operation of desulfurization system and improving the environment quality in power plant. Based on the desulfurization power price policy, this paper analyzes the cost and benefit structure of the wet flue gas desulfurization system in Chinese power plant; that puts forward the calculation methods of total cost present value, to...

H-ZSM5, Zn/H-ZSM5, and Co/H-ZSM5 catalyze thiophene desulfurization with high H2S selectivity using propane as the exclusive hydrogen source. Desulfurization rates and selectivities were much higher than at the H2 concentrations present during propane reactions. Zn+2 and Co+2 cations at exchange sites increased desulfurization rates. On H-ZSM5, desulfurization rates and selectivities with propa...

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...

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...

Depending on the desulfurization reaction temperature, it can be divided into fly ash generated at hightemperature furnace zone and at low-temperature flue gas zone. For simulating those two kinds of desulfurization ash, the ordinary fly ash mixed with different weight percentage of CaSO4·2H2O is divided into 2 groups, the first group is followed by calcining at 900°C, another drying at 100°C. ...
