C4F7N is considered to be the most potential alternative gas for SF6. However, harmful decomposition by-products generated by discharge or overheating faults will pose threat safe operation and service life of insulated equipment (GIE). Herein, we investigated adsorption performance γ-Al2O3 on its products evaluate possibility using it as adsorbent exhaust treatment material. It found that demo...

Effective abatement of the greenhouse gas sulphur hexafluoride (SF6) waste is great importance for environment protection. This work investigates size effect and surface properties γ-Al2O3 pellets on SF6 degradation in a packed bed dielectric barrier discharge (PB-DBD) system. Experimental results show that decreasing packing improves filamentary discharges promotes ignition maintenance plasma,...

Syngas production via dry reforming of methane was conducted over 5 wt%Ni + xWO3/γ-Al2O3 (x = 1, 3, 5, 7, or 9 wt%) catalysts at 700 °C and ambient pressure for 7.5 h in a tubular fixed-bed reactor. Textural, morphological, catalytic properties were investigated relation to the weight percent tungsten trioxide loading. The physicochemical evaluated using XRD, N2-physisorption, TGA, H2-TPR, CO2-...

Chemical warfare agents (CWAs) are highly toxic and fast-acting easy to cause large-scale poisoning humans livestock after being released. The activated carbon used for CWAs adsorption has disadvantages of limited capacity, aging deactivation. Metal oxides have environmental stability, they characterized by long lasting broad spectrum when thermal catalytic decomposition. Therefore, in this stu...

In this work, a coaxial dielectric barrier discharge (DBD) reactor was constructed to degrade the mixture of toluene and o-xylene, two typical benzene series. The Cu-MnO2/γ-Al2O3 series catalysts prepared by redox impregnation methods were filled into plasma device VOCs synergistically explore degradation effect. experimental results showed that introduction Cu-doped MnO2 catalyst significantly...

Dimethyl ether (DME) is considered an alternative hydrogen carrier with potential use in fuel cells and automotive domestic applications. hydrolysis to methanol a thermodynamically limited reaction catalyzed by solid-acid catalysts, mainly Al2O3 zeolites. Moreover, it the rate-limiting step of DME steam reforming reaction, which employed for production cell feeding. In present study, performanc...

Four types of nickel catalysts supported on aluminum oxide (Ni/Al2O3) with different nickel loadings were synthesized using the co-precipitation method and were used for the hydrogenation of levulinic acid (LA) to prepare γ-valerolactone (GVL). The synthesized Ni/Al2O3 catalysts exhibited excellent catalytic activity in dioxane, and the activity of the catalysts was excellent even after being u...

We explored the B-C-O system at pressures in the range 0-50 GPa by ab initio variable-composition evolutionary simulations in the hope of discovering new stable superhard materials. A new tetragonal thermodynamically stable phase B4CO4, space group I4[combining macron], and two low-enthalpy metastable compounds (B6C2O5, B2CO2) have been discovered. Computed phonons and elastic constants show th...
