概要:

Targeting resource management and the effective utilization of waste of plant origin, experiments involving NO (nitrogen monoxide) adsorption by charcoal filter were conducted. The charcoal filter used is made from driftwood into dams and from waste lumber. According to the experimental results, the amount of equilibrium NO adsorption of the charcoal filter was 40-1300 times as much as that of the soil filter used in the previous paper. Based on the experimental … results of the NO breakthrough curve from the charcoal filter and the theoretical analysis of the mass transfer process, the NO adsorption characteristics of the charcoal filter were recognized. It was experimentally and theoretically shown that the fundamental main mechanism of the adsorption by the charcoal filter is the surface diffusion into the micro-pores except in the short early stage, during which the Knudsen diffusion in the meso-pores is the main mechanism. A practical equation that properly shows the stepwise change in the adsorption rate was proposed, and the physical meaning of parameters in the equation was explained through interpretation of the adsorption mechanism. The adsorption ability would differ based on the kind of materials involved, and that was left for future work examining the details of the charcoal filter structures. 続きを見る
