The adequate configuration and the effect of reduction was studied for In2O3-ZrO2/SAPO-34 catalyst with aim improving its performance (activity selectivity in pseudo-steady state) hydrogenation CO, CO2 CO2/CO (COx) mixtures into olefins. experiments were carried out a packed bed reactor at 400 °C; 30 bar; H2/COx ratio 3; CO2/COx ratios 0, 0.5 1; space time (referred to as In2O3-ZrO2 mass) 3.35 ...

The present work aims at further investigating a previously studied PdZn/ZrO2+SAPO-34 bifunctional catalyst for CO2 conversion. High activity and selectivity propane was proved the results obtained by NAP-XPS measurements CO adsorption liquid-nitrogen temperature (LNT) followed FT-IR spectroscopy are shown. After reduction, we confirmed formation of PdZn alloy. At LNT, Pd carbonyl IR band shows...

Background: The removal of toxic metals from sewage and wastewaters is one of the most important concerns in the twenty first century. The removal of poisonous Cr(VI) from aqueous solution by different low-cost available nanoporous adsorbents was investigated in the present study.  Methods: Fumed silica, bentonite (BN), hydrotalcite (HT), MCM-41, Na-Y, mordenite (MOR) and SAPO-34 were ...
