“…Similar trend of COD reduction is observed at higher temperatures also. Contrary to the findings of several authors [23][24][25], the effect of the reactor wall on the thermolysis of the DWW was notobserved. Fig.…”

“…Intermediate products such as MMP and formic acid behave as "refractory" compounds to oxidation which limit the mineralization process. A similar comment was made also in the published literature (Bjerre and Sorensen, 1992;Shende and Mahajani 1997; and Levec 1999; Schramm and Hua 2001). Along with a base-catalyzed hydrolysis, the methylphosphate esters can be degraded via OH radical oxidation, as exemplified by the DVMP degradation in Scheme 4.…”

The calculated pseudo-first-order rate constants were dependent on the dissolved oxygen level at low O(2) flow rate, but somewhat independent on the initial pH. The decrease of pH during the irradiation suggests the formation of organic acids. The presence of organic intermediates was confirmed also by TOC measurements. A plausible reaction mechanism of DDVP degradation through the UV-A/TiO(2) process was proposed.

The potential of maize silage as a feedstock to produce bioethanol was evaluated in the present study. The hydrothermal pretreatment with five different pretreatment severity factors (PSF) was employed to pretreat the maize silage and compared in terms of sugar recovery, toxic test, and ethanol production by prehydrolysis and simultaneous saccharification and fermentation. After pretreatment, most of the cellulose remained in the residue, ranging between 85.87% by the highest PSF (185 degrees C, 15 min) and 92.90% obtained at the lowest PSF (185 degrees C, 3 min). A larger part of starch, varying from 71.64% by the highest PSF to 78.28% by the lowest, was liberated into liquor part, leaving 8.05-11.74% in the residues. Xylan recovery in the residues increased from 44.25% at the highest PSF to 82.95% at the lowest. The recovery of xylan in liquor changed from 20.13% to 50.33%. Toxic test indicated that all the liquors from the five conditions were not toxic to the Baker's yeast. Pretreatment under 195 degrees C for 7 min had the similar PSF with that of 185 degrees C for 15 min, and both gave the higher ethanol concentration of 19.92 and 19.98 g/L, respectively. The ethanol concentration from untreated maize silage was only 7.67 g/L.
