利用轻度炭化的玉米秸秆炭脱除沼气中硫化氢的研究
Study of biogas desulphurization by incomplete carbonated corn stalk biochar
摘要
Abstract
In this study,the incomplete carbonated biochar was made from corn stalks with a patented method.The obtained biochar was flushed with distilled water or modified with alkaline aqueous solution.The micro-structure of biochar was observed with a scanning electron microscope (SEM) and the properties were characterized by a Fourier transform infrared spectroscope (FTIR).The biological structure of corn stalks was maintained well in the biochar according to the observation of SEM images.Hydroxyl groups could be found in all the biochar samples and ester carbonyl group absorbance peak disappeared in the alkaline modified biochar.The H2S adsorption property of biochar was carried out in a fix-bed setup.The results exhibited that the biochar flushed with water had the best H2S adsorption capacity,high pH value could improve the adsorption properties of biochar.The adsorption process could be well described with the equation of Bangham.关键词
