Thermal Decomposition of Cellulose Crystallites in Wood

Holzforschung, 2001
Summary Decomposition of cellulose crystallites in wood during pyrolysis was studied by X-ray diffraction using a tension wood of Populus maximowiczii (cottonwood), which contains highly crystalline cellulose. X-ray diffraction profiles were recorded at varied temperature up to 360°C.

Measuring the Decomposition of Down Dead-Wood

2008
Down and dead-wood plays an important ecological role in forest ecosystems, and the decomposition of this material may contribute significantly to forest net ecosystem production. Dead-wood decomposition can be measured in three ways: measuring variability in density over a chronosequence of dead-wood, measuring density changes during a time series of ...

A Mathematical Model of the Thermal Decomposition of Wood

Combustion Science and Technology, 1972
Abstract A mathematical model developed for computer solution of heat transfer problems involving change of phase heat effects was applied to the prediction of transient temperature distributions and volatile product evolution rates in decomposing wood specimens.

Decomposition of Wood Particles in Fluidized Beds

Industrial & Engineering Chemistry Research, 2004
High-temperature biomass pyrolysis is the first step of the thermochemical process taking place in a fluidized bed gasifier; it influences strongly the final product gas composition, specifically h...

Decomposition of Wood by Brown-Rot Fungi

1989
Many different types of organisms deteriorate wood, but the greatest damage is microbial decay caused by fungi (Figures 1 and 2). Fungal decay is by far the most serious type of damage to wood in use, because it can cause structural failure that, at times, is very rapid.

Nitrogen Source in Fungal Decomposition of Wood

Nature, 1963
IT is a well-known fact that the nitrogen content of the medium is one of the limiting factors in fungal decomposition. Two experiments were carried out in order to determine whether the effective destruction of wood by Merulius lacrymans is sustained solely by the amount of nitrogen originally present in the wood, or whether any fixation of nitrogen ...

The use of wood veneer in decomposition experiments

Applied Biochemistry and Biotechnology, 1984
Lignified cellulose (sycamore wood veneer) has been included in a range of simple biological soil tests that are being assessed as field tests to demonstrate the decomposing abilities of soils and the effect of management practices.

Thermal decomposition kinetics of wood pyrolysis

Combustion and Flame, 1972
Solution of the equations of energy and mass conservation describing the thermal response of charringpolymeric solid fuels exposed to a fire environment requires a knowledge of the pyrolisis-rate equations. Because the results of conventional thermogravimetric experiments (static or dynamic) on small samples are speculated in the literature to be ...

Decomposition of Wood in Landfills: Review of Literature

For decades, landfill-sites have been used as the main disposal method in Australia for wood and engineered wood products. Even though the long-term storage of sawn-wood products in landfill-sites have been reasonably well-documented, knowledge of the carbon in engineered wood products is limited and largely undocumented.
