West Conshohocken, PA: ASTM International. 1. Periodic disorder along ramie cellulose microfibrils. At the end of this cellulose pre-treatment process, the Erlenmeyer flask was rapidly cooled by dipping it in a 1 L beaker containing ice-cold water and the appropriate amount of basic solution [NaOH or NH3(aq)] added dropwise with agitation, until the desired acid/base molar ratio (R2) was achieved. Variations of this method have the potential of being economically attractive if a minimum acid/cellulose ratio is used for the ionic liquefaction step and a high glucose yield is obtained after post-hydrolysis. Enzymatic hydrolysis is limited by biomass-water interactions at high Glucose produced by catalytic hydrolysis of cellulose is an important platform molecule for producing a variety of potential biobased fuels and chemicals. 184, 285 .

At a post-hydrolysis temperature of 121C and with the same conditions as in Figure 9, except for partial neutralization with H+/OH molar ratio of 2.3 and 20 wt% NaOH, the highest glucose yield of 88% was obtained (See Figure 7) for a post-hydrolysis time of 10 min. Since renewable fuels have a carbon balance close to neutrality (Lee and Lavoie, 2013), they are essential to mitigate the adverse climate change and global warming effects caused by greenhouse gas emissions from petroleum-derived liquid fuels. Polym. Prod. 11, 2533 (2015). ACS Biomater. Cellulose 24, 44794491 (2017). The high yields (close to 100%) obtained with the above best sets of conditions show that this process could nearly be as efficient as the standard ASTM E1758-01 method. Soft Matter 9, 952959 (2013). Bajpai, P. Green Chemistry and Sustainability in Pulp and Paper Industry (Springer, 2015). The first step (pre-treatment) decrystallizes cellulose while the second step (post-hydrolysis) converts the amorphous cellulose to glucose. Filson, P. B. High glucose yields from the hydrolysis of cellulose dissolved in ionic Cellulose hydrolysis yields with an industrial cellulase (Ctec2) were measured on pretreated wheat straw and spruce from 5 to 30% dry matter (DM), and compared to yields of an older industrial cellulase mixture (Celluclast 1.5L/Novozym188). Carbohydr. Their pre-treatment step was done at a mass ratio of H2SO4/dry wood chips of 2.5 and 80 wt% H2SO4, and distilled boiling water was added to the so-formed paste to achieve 26 wt% H2SO4. Biomacromolecules 6, 10481054 (2005). First, it can be observed that the standard deviation among the triplicates at the most efficient conditions (giving highest glucose yields) is very small, such that the associated error bars are hardly distinguishable in Figure 8.

Solution-phase EPR studies of single-walled carbon nanotubes. Curr. The cellulose hydrolysis process involved seven main parameters and the influence of each parameter on glucose yield was investigated in turn, while keeping the other parameters constant.

For example, most efficient post-hydrolysis time at 121C and H+/OH molar ratio of 2.3 was less than 10 min while being 60 min or more for an H+/OH molar ratio of 1.7.

However, the curve obtained with the 20 wt% NaOH solution reached a higher maximum glucose yield at higher H+/OH molar ratios. A. De France, K. J. et al.
