Biobutanol Production from Plant Biomass

Without plant biomass grinding, butanol accumulated at a concentration of up to 0.1 g/l. With prior grinding of rape biomass, butanol accumulation in the culture fluid increased, the highest level of butanol accumulation was observed at the grinding degree of 200 mesh (0.076 mm).

Pre-treatment of Oil Palm Biomass for Fermentable Sugars ...

Sun and Cheng reported that the selection of the pre-treatment method for chipping, grinding, and milling is depending on the final particle size of the biomass, usually in the range of 10–30 mm after chipping, and 0.2–2 mm after milling or grinding. Biomass size smaller than 400 mesh (0.04 mm) has little effect on the rate and yield of ...

Sandwich Stump Grinding - Cape Cod Tree

A stump grinder or stump cutter is a power tool or equipment attachment that removes tree stumps by means of a rotating cutting disc that chips away the wood.. Stump grinders can be the size of a lawn mower or as large as truck. Most accomplish their task by means of a high-speed disk with teeth that grinds the stump and roots into small chips.

Ultrafine grinding of poplar biomass: effect of particle ...

Abstract This paper shows that mechanical ultrafine grinding of poplar wood is an efficient pretreatment approach to enhance its reactivity during liquefaction. The microstructural features and chemical properties of biomass samples with different particle morphology were studied. In particular, we found that more cellulose and hemicellulose were exposed on the …

Catalytic Hydrothermal Carbonization Treatment of …

Grinding and sieving of the biomass are also common, as smaller particle sizes have been shown to result in higher quality activated carbons. Şentorun-Shalaby et al. found an increasing surface area when particle size was reduced from 3.35–4 mm to 1.7–3.35 mm and again to 0.85–1.7 mm, however, the solid yield was also reduced [ 20 ].
