The oxidation of methane, the main component natural gas, to selectively form oxygenated chemical feedstocks using molecular oxygen has been a long-standing grand challenge in catalysis. Here, gold nanoparticles supported on zeolite ZSM-5, we introduce method oxidize methane methanol and acetic acid water at temperatures between 120 240 °C absence any added coreductant. Electron microscopy reve...

isotherm equation is one of the important scientific bases for adsorbent selection. there are different isotherms that do not account for an adsorbate, different chemisorption geometries on the nanoporous surface. it is interesting to introduce a general isotherm, which considers different chemisorption geometries of an adsorbate on nanoporous surfaces. in this study, an isotherm for non-dissoci...

At present, a number of models are available describing the adsorption of a fluid in a random porous medium. In this paper, some exact and analytical results are presented. All the results are obtained for an ideal gas adsorbed in various porous matrices. It is shown that the calculations are not always trivial. In some cases of complicated matrices, it is impossible to obtain any analytical re...

Perturbation chromatography with multi component gas carrier and non-equilibrium thermodynamics liner law was applied for discussion of the interference effect and the displacement effect on mass transfer in multi component gas adsorption. Moment analysis method and stop & go simulation method were utilized to obtain each mass transfer parameters of adsorbate gases. Dependency of micropore diff...

By doping 1%Ru/m-ZrO2 with sodium, selectivity tuning between CO and CH4 during CO2 hydrogenation was achieved by controlling the relative rates of reverse water-gas shift methanation. increasing basicity through Na loading: (1) formate C-H bond is weakened in DRIFTS adsorbed CO, accelerating formation promoting at Ru/m-ZrO2 interface; (2) coverage increases on ensembles Ru atoms responsible fo...

We use Monte Carlo simulations to study the adsorption and separation of the natural gas components in IRMOF-1 and Cu-BTC metal-organic frameworks. We computed the adsorption isotherms of pure components, binary, and five-component mixtures analyzing the siting of the molecules in the structure for the different loadings. The bulk compositions studied for the mixtures were 50 : 50 and 90 : 10 f...
