Реферат: A method for separating acid and sugars obtained from liquids resulting from the acid hydrolysis of a material containing at least one of cellulose and hemicellulose is disclosed, comprising adding the liquids to a separation unit comprising a bed of anionic exchange or exclusion chromatographic material whereby the acid is adsorbed onto the chromatographic material, thereby producing a series of first fractions comprising sugar solutions and a later series of fractions comprising acid solutions. A process for an economical, energy efficient production of ethanol from municipal solid waste and other cellulosic feedstocks is also disclosed.
