Three heteropolyanion substituted hydrotalcite-like compounds (HPA-HTLcs) including Mg₉Al₃(OH)₂₄[PW₁₂O₄₀](MgAl-PW₁₂), Mg₉Al₃(OH)₂₄[PMo₁₂O₄₀] (MgAl-PMo₁₂) and Mg₁₂Al₄(OH)₃₂[SiW₁₂O₄₀] (MgAl-SiW₁₂), were synthesized, characterized and used as catalysts for the oxidative desulfurization of simulated oil (dibenzothiophene, DBT, in n-octane). MgAl-PMo₁₂ was identified as an effective catalyst for the...

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...

A mechanistic analysis of the various mass transport and kinetic steps in the microbial desulfurization of dibenzothiophene (DBT) by Rhodococcus erythropolis IGTS8 in a model biphasic (oil-water), small-scale system was performed. The biocatalyst was distributed into three populations, free cells in the aqueous phase, cell aggregates and oil-adhered cells, and the fraction of cells in each popu...

An alumina-supported nickel catalyst was prepared by impregnation of Ni2+ solution onto mesoporous alumina under microwave irradiation (denoted as M-Ni/Al2O3). For comparison, a catalyst with the same nickel content was prepared by conventional impregnation method (denoted as UM-Ni/Al2O3). Both M-Ni/Al2O3 and UM-Ni/Al2O3 catalysts were applied to the syngas (H2 + CO) production by methane oxy-s...

The highly ordered mesoporous silica media, SBA-15, was synthesized and incorporated with iron, aluminum, and zinc oxides using an incipientwetness impregnation technique. Adsorption capacities and kinetics of metal-impregnated SBA-15 were compared with activated alumina which is widely used for arsenic removal. Media impregnated with 10% of aluminum by weight (designated to Al10SBA-15) had 1.9...

In this work, the highly active polyoxometalate (PW2Mo2) with Venturello structure and its corresponding catalyst were applied in catalytic desulfurization for first time. PW2Mo2 as an component was effectively encapsulated hollow periodic mesoporous organosilica (HPMOS) to form nanoreactor PW2Mo2@HPMOS, where central cavity shell facilitate mass transfer both provide a stable place react organ...

Heavy oil pollution caused by tanker accidents is one of the most important environmental issues in the world. The pollution is related to the impact on marine organisms, since heavy oil consists of toxic substances such as polycyclic aromatic hydrocarbons (PAHs), heavy metals and benzol. However, the effect of heavy oil on the fish immune system is not well understood. In the present study, th...
