Method of producing glucose from papermaking sludge using concentrated or dilute acid hydrolysis

摘要

Glucose is obtained from papermaking sludge by first removing calcium carbonate from the sludge to produce a mixture substantially depleted of calcium and containing cellulose; and then hydrolyzing the calcium-depleted mixture using either a dilute or a strong acid. The glucose, as well as calcium salts removed from the sludge, may be isolated and used in numerous applications.
