This work focuses on the study of a pressure swing adsorption (PSA) process for biogas upgrading using carbon molecular sieve adsorbent. Adsorption equilibrium and diffusion data pure components were used to predict multicomponent behavior. To validate prediction at different concentrations, breakthrough curve experiments performed gas mixture pressures (0.25, 0.5, 1, 5 bar). Based basic information, model was performance two-column PSA unit. The as feed 60% CH4 40% CO2 with swings between...
The study focuses on the equilibrium of dynamic biosorption in single and binary systems containing Cu(II) Ni(II) ions using Sargassum filipendula (a marine alga). experiments were performed fixed-bed columns with both single-component bi-component metal solutions (using different molar concentrations). Experimental data fitted models such as Langmuir, Langmuir inhibition, Jain Snowyink Langmuir–Freundlich equations. pure solution presented adequate capacities for Ni(II). In preferential...
Abstract The aqai palm stalk (Euterpe oleracea) is a food residue used in its natural form (AS) and also protonated (AAS) as biosorbents for the removal of textile dye Procion Blue MX-R from aqueous solutions. This biosorbent was characterized by infrared spectroscopy, scanning electron microscopy, nitrogen adsorption-desorption curves. effects pH, dosages, shaking time on biosorption capacities were studied. In acidic pH region (pH 2.0) favorable. minimum contact to obtain equilibrium 8...
Abstract There has been little research into the effects of water hardness and pH surface waters on adsorption caffeine activated carbons. The aim this study was to determine influence these characteristics different Caffeine from aqueous phase studied using biomass derived carbons (DD: dende coco BB: babassu coco) a commercially available activate carbon (NO: Norit® GAC 1240 plus). functionalized in an inert atmosphere also were denominated DI, BI, NI. Results highlight importance...
