METHOD FOR PRODUCING USEFUL CARBON FROM FOOD LEES

PURPOSE:To efficiently produce a useful carbon such as active carbon or desalted carbon from food lees such as soy lees. CONSTITUTION:The food lees such as soy lees are carbonized at 150-700 deg.C and after an acetic acid liquid and an oily liquid is collected, the residual carbon is activated at 80...

Zusammenfassung:	PURPOSE:To efficiently produce a useful carbon such as active carbon or desalted carbon from food lees such as soy lees. CONSTITUTION:The food lees such as soy lees are carbonized at 150-700 deg.C and after an acetic acid liquid and an oily liquid is collected, the residual carbon is activated at 800-1300 deg.C to obtain an active carbon. The desalted active carbon is obtained after washing and demineralizing the residual carbon. The desalted carbon is obtained by heat treating at 400-1000 deg.C instead of the activation treatment. And the desalted carbon is obtained by carbonizing the food lees at 400-1000 deg.C and washing the recovered carbon without independently providing heat treating process.
