Abstract

This method has been developed to utilize the residues from the manufacture of furfural by acid treatment of corn cobs or oat hulls. The residue is mixed with 7.5% by wt. ZnO and 70% HCl (Sp Gr 1.20) and allowed to stand 24 hours. It is then dried and destructively distilled at 550°C. The ash is leached out with 1% HCl and the char dried and heated to 850°C. Treatment yields a char which is the equal of any vegetable char now on the market.
