【摘要】：利用油茶果壳为原料,采用直接炭化法制备油茶果壳炭,主要讨论自制油烟吸附装置中油烟入口浓度、体积空速和吸附床层高度3个因素对穿透曲线和吸附容量的影响。结果表明,在油烟浓度为50 mg/m3,体积空速为1.7 h-1,吸附剂床层高度为40 cm的条件下,最大吸附量可达到122.6 mg/g;保护作用时间随油烟浓度的升高、体积空速的增大、吸附剂床层高度的减小而变短。SEM分析表明,油茶果壳炭含有众多孔径不一的孔隙,有利于油烟这种含有多种组分污染物分子的吸附作用。
[Abstract]:The char of Camellia oleifera shell was prepared by direct carbonization from the shell of Camellia oleifera. The inlet concentration of oil fume in a self-made oil fume adsorption device was discussed. The effects of three factors, volume space velocity and adsorption bed height, on the penetration curve and adsorption capacity were studied. The results showed that under the conditions of oil smoke concentration of 50 mg / m ~ (-3), volume space velocity of 1.7 h ~ (-1) and adsorbent bed height of 40 cm, The maximum adsorption capacity can reach 122.6 mg / g, the protective time increases with the increase of oil smoke concentration, the volume space velocity increases, and the height of adsorbent bed decreases. SEM analysis shows that the char of Camellia oleifera shell contains many pores with different pore sizes. It is beneficial to the adsorption of oil fume, which contains a variety of pollutants.
