Abstract
The dilute acid pretreatment of biomass aspen wood and wheat straw at high solids concentrations (up to 40 wt%) has been investigated. It produces a concentrated monomeric soluble sugar stream (mainly xylose) with little degradation of the available sugars and a solid residue containing cellulose and lignin. The cellulose remaining in the residue from both aspen and straw pretreated at either 140 degree C or 160 degree C was highly digestible with commercially available enzymes. A somewhat higher acid consumption for wheat straw compared with that for aspen can be alleviated by a cation-removal step.
