Size reduction is the first step for manufacturing biofuels from woody biomass. It is usually performed using milling machines and the particle size is controlled by the size of the sieve installed on a milling machine. There are reported studies about the effects of sieve size on energy consumption in milling of woody biomass. These studies show that energy consumption increased dramatically as sieve size became smaller. However, in these studies, the sugar yield (proportional to biofuel yield) in hydrolysis of the milled woody biomass was not measured. The lack of comprehensive studies about the effects of sieve size on energy consumption in biomass milling and sugar yield in hydrolysis process makes it difficult to decide which sieve size should be selected in order to minimize the energy consumption in size reduction and maximize the sugar yield in hydrolysis. The purpose of this paper is to fill this gap in the literature. In this paper, knife milling of poplar wood was conducted using sieves of three sizes (1, 2, and 4 mm). Results show that, as sieve size increased, energy consumption in knife milling decreased and sugar yield in hydrolysis increased in the tested range of particle sizes.

Influent Concentration

Black liquor was processed with wet air oxidation technology in these experiments. Influence of its influent concentration was researched. COD, absorbance, turbidity and pH of the water samples were measured and analyzed. The results showed that: the treatment effect of each index in black liquor treatment with wet air oxidation method gradually weakened with the increase of influent concentration from the overall point of view; when papermaking black liquor was processed by wet oxidation, the water samples was weak alkaline basically, with pH in between 7.83 to 8.70. COD removal, decolorization removal and turbidity removal basically improved with the extension of time, the COD removal and decolorization removal can reach 50 % or more basically. When influent concentration was greater than 5500 mg/L, turbidity removal was less than 40 %. So the influent concentration of the black liquor in wet oxidation treatment should not be too large, the influent concentration of 2500 mg/L to 4000 mg/L is appropriate.
