Abstract

The cow manure compost was carbonized in temperature range of 400-1000 ℃. The water vapor adsorption property of the prepared char was investigated. A large increase of amount adsorbed of water vapor was found around relative pressure of 0.80. However, in the char prepared at carbonization temperature of 1000 ℃, a large increase of amount adsorbed was disappeared. It was clarified that the increase of the amount adsorbed was attributed to KCl contained in the char. The humidity control property of the cow manure compost char was also investigated. The compost char showed the stable behavior of the adsorption-desorption of water vapor during the cyclic humidity change. It was found that the humidity control property of the cow manure char was superior to that of the commercial wood char for the humidity conditioning.
