AbstractIn the present work, composite membranes were developed for separation of hydrogen from its mixtures with other gases. The composite membranes were characterized by single gas permeation and scanning electron microscopy. Gas transport properties have been determined for four gases (H2, CH4, N2, CO2). The influence of cross-linking on transport was measured. H2/CH4 selectivity values up to 115 were obtained. The resulting membranes have a selectivity of H2/CH4 close to intrinsic selectivi...

AbstractTwo non-functionalized hypercrosslinked polymeric resins type Macronet (MN 202 and MN 250) were employed to remove nhexane vapors from gas phase. A comparison of the equilibrium behavior of these hypercrosslinked resins and a bituminous granular activated carbon was made. The initial n-hexane concentration in the air stream ranged from 2100 to 4500 ppm and the adsorption temperatures were 30oC, 40oC and 50oC. The results showed that the MN 250 presents the higher adsorption capacities of...

The studies were made by correlating the dynamic implementation of hydraulic works with the results of the environmental monitoring, biotic and abiotic factors. The hydraulic works designed to be built-up on the Bala branch, raised issues regarding sturgeons’migration in thi...
