Hydrogen is a priority energy vector for transition. Its production from renewable feedstock like ethanol suitable many applications. The performance of Ni catalyst supported on samaria-doped ceria in the hydrogen by reforming investigated, adding Sm2O3 to CeO2 molar ratios 1:9, 2:8, and 3:7. A CeO2-supported was also evaluated comparative purposes. supports were prepared coprecipitation method incorporated incipient wetness impregnation obtain catalysts with Ni/(Ce+Sm) ratio 4/6....
A density functional theory (DFT) analysis has been conducted for the gas-phase hydrodechlorination (HDC) of dichloromethane (DCM) with palladium catalyst to achieve a better knowledge reaction mechanism involved in HDC process, which constitutes an emerging technology treatment organochlorinated contaminants. The computational study included effect size, oxidation state, and spin configuration Pd cluster on adsorption H2 DCM reactants surface. Calculations described activation by clusters...
The effect of the nature catalyst components has been analyzed in hydrodechlorination carbon tetrachloride to chloroform. Active carbon, alumina, silica, and sepiolite were used as supports Ru, Rh, Pd, Pt, Ni metallic phase. catalysts characterized by CO chemisorption, TPR, XPS. Reaction was carried out at 373 413 K a slurry semibatch reactor. Dispersion containing different metals are very similar, while values corresponding Pd supported on carriers follow trend Pd/Al2O3 > Pd/carbon Pd/SiO2...
Conversion of chloroform (TCM) by gas-phase catalytic hydrodechlorination (HDC) has been addressed to maximize the selectivity ethane and propane.
Upgrading of waste dichloromethane to produce olefins has been performed by hydrodechlorination (HDC) using bimetallic catalysts consisting Pd-Fe/CNT, Pd-Sn/CNT and Pd-Ag/CNT. Pd/CNT was also studied. Pd-Fe/CNT showed the best performance in terms activity (X≈81 %) stability, with highest selectivity (>60 %, mainly C2H4), at 350 °C, which could be attributed existence stable Pd-Fe interaction. Characterization results density functional theory calculations suggest that incorporating Fe atoms...
The behavior of a commercial (CE) and homemade (CH) palladium/carbon catalyst in the gas-phase hydrodechlorination dichloromethane (DCM) has been investigated, at low concentration, fixed-bed microreactor, with view application to treatment residual gas streams. influence space time (1.0−6.6 kg h mol-1), reaction temperature (423−623 K), H2/DCM molar ratio (50−400) was investigated. catalysts showed high performance, DCM conversions up 97% selectivities nonchlorinated products ∼80%....
Gas catalytic hydrodechlorination (HDC) of trichloromethane (TCM) and dichloromethane (DCM) was analyzed using Pd (1 wt.%) on different zeolites as catalysts. The aim this study to know the surface properties catalysts reaction conditions that promote yield light hydrocarbons in reaction. Five zeolite supports were used from three commercial (KL, L-type; NaY, Faujasite; H-MOR, Mordenite). KL NaY submitted ionic exchange treatments order increase their acidity analyze effect activity...
The design of new anode materials to promote the reforming methanol is important for development intermediate temperature direct solid oxide fuel cells. A previous study showed Pd/CeO2−Sm2O3 be a good candidate. Here, influence calcination pretreatment support and reduction catalyst on steam are investigated, as they can become key factors in performance catalyst. Conversion, H2 yield, TOF were considerably higher when was calcined at 800 °C (Pd/CS-800) instead 1000 (Pd/CS-1000)....
