Kinetic characterization for pretreatment of timber varieties and switchgrass using diluted acid hydrolysis

“…To minimize the errors, a larger amount of sample and acid could be used. The results of structural carbohydrate analysis are similar to the results published previously (Brooks et al, 1978). The comparison of the results will be discussed in Chapter 6.…”
