Abstract: Experiments were conducted for the optimal prefabrication technology of carbonized rice hull for culture media by orthogonal test. Effects of carbonization temperature and time on char yield and physicochemical properties were investigated. The optimal condition were carbonization temperature of 350℃, carbonization time of 40 minutes. Under this condition, char yield was 51.71%. Char with pH value 8.06, caloric value of 19 937 J/g, fixed carbon content of 41.16% could be produced.

Key words: culture media, carbonized rice hull, orthogonal test, carbonization technology
