Desulfurization adsorbents were prepared from the mixtures of sewage sludge and metal sludge of various compositions and individual sludges by pyrolyses at 650, 800 and 950°C. The resulting materials were used as adsorbents of hydrogen sulfide from simulated digester gas mixture. The adsorbents before and after H 2 S removal were characterized using adsorption of nitrogen, elemental analysis,...
Adsorbents for removal of hydrogen sulfide from moist air were prepared from sewage sludge, waste oil sludge and their 50:50 mixture by pyrolysis at 650 and 950°C for either half an hour or an hour. The resulting materials were characterized using sorption of nitrogen, thermal analysis, pH measurements and X-ray diffraction. Their catalytic performance was evaluated in hydrogen sulfide reactive adsorption...
