Catalytic liquefaction of municipal sewage sludge over transition metal catalysts in ethanol-water co-solvent
Catalytic liquefaction of (Municipal sewage sludge) MSS over transition metal catalysts in ethanol-water co-solvent (EWCS) was investigated. The effect of operating parameters like temperature, holding time, and ethanol-water ratio was discussed. CuSO4 was selected as the most efficient catalyst. The highest biocrude yield (47.45%) and liquefaction conversion (97.74%) was both obtained at the s...
متن کاملSewage Sludge-derived Adsorbents for H2s Removal
Various methods have been used to dispose of or utilize municipal sewage sludge (1), including incineration, landfilling, road surfacing, conversion to fertilizer, compression into building blocks, and carbonization (1-4). Since 1976 several patents have been issued on carbonization of sewage sludge and various applications of the final materials (4-7). Carbonization of sludge in the presence o...
متن کاملcatalytic ozonation of phenol using copper coated pumice and zeolite as catalysts
background: catalytic ozonation has recently been applied as a new method of contaminant removal from water and wastewater. in this study, copper coated pumice and zeolite were used to catalyze the ozonation of phenol as a target pollutant from aqueous solutions. methods: the pumice and zeolite stone were modified by cuso 4 (1n). modified pumice and zeolite were characterized by adsorption/deso...
متن کاملBiological testing of a digested sewage sludge and derived composts.
Aiming to evaluate a possible loss of soil habitat function after amendment with organic wastes, a digested sewage sludge and derived composts produced with green residues, where biologically tested in the laboratory using soil animals (Eisenia andrei and Folsomia candida) and plants (Brassica rapa and Avena sativa). Each waste was tested mimicking a field application of 6ton/ha or 12ton/ha. Av...
متن کاملSewage Sludge-derived Materials as Adsorbents of So2
Adsorption of sulfur dioxide on carbonaceous materials has been extensively studied (1-18). Activated carbon and activated carbon fibers have been found to be efficient adsorbents for the low temperature removal of SO2. It is believed that sulfur dioxide is adsorbed with two adsorption energies on activated carbons (3-12). The low energy, about 50 kJ/mol, corresponds to weak physical adsorption...
