Simultaneous production of α-cellulose and furfural from bagasse by steam explosion pretreatment [PDF]

open access: yes, 2008
Sugar cane bagasse was pretreated by steam explosion for the simultaneous production of furfural and α-cellulose pulp. The components of bagasse were fractionated after steam explosion. The details of the process are as follows.

Extraction and structural study of hemicellulose B from tall fescue (Festuca arundinacea) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University [PDF]

open access: yes, 1971
1.1 Hemicellulose The structural carbohydrates are mixtures of polysaccharides which together with lignin, constitute the cell wall. Usually they are divided into three fractions: pectic substances, hemicellulose and cellulose.1 Pectins, widely ...

High-density short aspen fiber networks have similar tensile properties as networks from longer spruce fibers

open access: yesMaterials & Design
Mechanical behavior of high-density oriented spruce and aspen fiber networks from mildly delignified holocellulose fibers is investigated. Such recyclable, eco-friendly fiber networks are of interest for molded fiber materials and biocomposites.

Research on so-called "Holocellulose pulp" from Hard Woods

open access: yesJAPAN TAPPI JOURNAL, 1955
Applying, as the first stage, the neutral sulphite semi-chemical pulping process to beech tree and other several hard wood species common in this district (Shizuoka Prefecture), we got unbleached pulps containing various amounts of lignin by varying Na2SO3 percentage addition from 14 to 20 on the basis of dry chips and digesting time at 170°C from 2 to

Comparing carbon isotope composition of bulk wood and holocellulose from Quercus cerris, Fraxinus ornus and Pinus radiata tree rings

open access: yesForest@, 2004
Tree-ring δ13C is widely employed in ecophysiological studies, because it represents an integrated proxy of the ratio between photosynthesis (A) and stomatal conductance (g), which expresses the intrinsic water use efficiency (iWUE), strongly affected by
