Palladium-based catalyst can be employed for natural gas exhaust clean up due to its high activity for light hydrocarbon oxidation. Unfortunately, trace amounts of sulfur in the natural gas feed severely deactivate the catalyst. In this paper, SO2 adsorption over a monolithic Pd/Al2O3 oxidation catalyst is monitored in a time-resolved manner in the presence of 100 ppm SO2 under simulated aging ...

An important method in oil and gas exploration is vertical seismic profile (VSP) to estimate rock properties in drilling well. Quality factor is also the crucial point of seismic attenuate in VSP data. In the present study, this factor was used to evaluate the hydrocarbon potential of Kangan Formation in one of the Persian Gulf oil fields using VSP zero offset method. Quality factor was estimat...

Bioremoval and bioreduction activities of hydrocarbon (diesel) isolation from environmental samples were studied by the activity of biosurfactant production, and calculating emulsification index, gravimetric, and FTIR analysis along with the estimation of bacterial biomass. Sample from soil near petrol, diesel pumps and water sample from Thesjaswini River near Padannakad, Kasaragod, Kerala, Ind...

The present study focuses on the membrane activity of antimicrobial peptides different secondary structure: bactenecin, an peptide, which forms a loop stabilized by single disulfide bond; defensins, beta-sheet structure that are three bonds; and pediocin, lantibiotic with combined structure, including both alpha-helix regions. It has been found bactenecin ion-permeable nanopores various conduct...
