Name:Hydrogen sulfide,CAS:7783-06-4.Use:Can be used for the conversion of sulfur and sulfuric acid, the production of sodium sulfide and sodium hydrosulfide, or for the production of organic sulfur compounds such as thiophene, mercaptans and sulfide.Buy
It is well known that the conversion reactions of a compound are related to the cell potential. However, considering that the cell potential has no variation (Fig. 10) in the tests carried out in this study, the results have been reported in function of the two parameters evaluated which ar...
At temperatures of −125.1 °C/−117.4 °C (A/B) both H2S and CO2simultaneously freeze and form a fine-grained mass of bright white (CO2) and yellow-greenish solids (H2S-α) of high reflectance (Figs.2eand3e, f). In order to investigate the composition and phase behavior o...
In summary, a series of zinc-cobalt-silicon ternary adsorbents with three different forms: cobalt-doped ZnO/SiO2, ZnO-Co3O4/SiO2, and zinc-doped spinel Co3O4/SiO2, were prepared by modulating the Co/(CO + Zn) molar ratio using a sol-gel method. Breakthrough tests indicated that ...
MSPN12-loaded Ni and Rh maintained stable POM activity at 700 °C during almost 100 h on stream, which were comparable to those for the commercial Rh(5)/Al2O3 catalyst in terms of methane conversion and H2 formation selectivity. Thus, the combination of structural stability and ...
The effects of five calculation parameters, namely, the sulfuric acid concentration, hydrogen iodide (HI) conversion ratio, molar flow rate of HIx phase, pressure, and reflux ratio at the distillation column, on thermal efficiency were evaluated. The results indicated that further research on the ...
This section mainly consists of the reformation reactor R-100, where reactants reach the thermodynamic equilibrium conversion at the specified pressure and temperature. For each simulated case, fixed the CH4/H2S feed molar ratio, the reaction temperature was set equal to the pinch temperature and ...
found that the combination of lanthanum based perovskite catalysts and a microwave discharge plasma enhanced the conversion of low concentration methane (3600 ppm) by around 30% compared to the plasma process in the absence of a catalyst at a same energy density of 10 W·m−2 [21,22]. ...
Reaction conditions: feed: H2S/CO2 molar ratio = 20:15; flow rate: 35 mL/min; catalyst bed volume: 15.0 mL. Figure 7. H2/CO molar ratio as a function of SEI in the plasma-induced CO2 and H2S conversion on the Ni-Mo sulfide/Al2O3 catalysts with various Ni/Mo molar ratios. ...
