Pyrolysis Kinetics of Wood and Wood Components

Chemical Engineering & Technology, 2005
The kinetics of pyrolysis decomposition reactions of wood and its components are described employing mathematical modeling tools for first and n th order reactions, autocatalytic reactions, and parallel first order and autocatalytic reactions. Secondary reactions may accelerate the reaction rate and a new autocatalytic reaction model was developed to ...

On the kinetics of thermal decomposition of wood and wood components

Thermochimica Acta, 1990
Abstract A kinetic analysis of the thermal decomposition of eucalyptus sawdust, cellulose and eucalyptus kraft lignin has been accomplished from temperature-programmed reaction experiments, using two different approaches: the first assumes an overall reaction model, whereas in the second, pyrolysis is viewed as a process consisting of multiple ...

Differential calometric analysis of wood and wood components

Wood Science and Technology, 1971
The prolysis of cellulose, hemicelluloses, lignin preparations, and wood was studied by differential calorimetric analysis (DCA) for the range of 25° to 800° C. The test samples included powdered and filter paper celluloses; hardwood xylan; softwood galactoglucomannans, compression wood galactan, and arabinogalactan; a synthetic (DHP), sulfuric acid ...

Detecting decay in wood components

2005
This paper reviewed current inspection techniques for decay detection and it provides guidelines on the use of various non-destructive (NDE) methods in locating and defining areas of decay within wood structural members. Visual inspection and probing techniques are commonly used for locating exterior deterioration of wood members.

Influence of wood extractives on two-component polyurethane adhesive for structural hardwood bonding

Journal of Adhesion, 2018
When bonding wood for structural applications, the wood–adhesive bond is influenced by a variety of factors. Besides the physical and mechanical properties of wood species, their chemical composition, e.g.

Thermal decomposition of wood: Influence of wood components and cellulose crystallite size

Bioresource Technology, 2012
The influence of wood components and cellulose crystallinity on the thermal degradation behavior of different wood species has been investigated using thermogravimetry, chemical analysis and X-ray diffraction. Four wood samples, Pinus elliottii (PIE), Eucalyptus grandis (EUG), Mezilaurus itauba (ITA) and Dipteryx odorata (DIP) were used in this study ...

Physicochemical Study of the Sorption of Pesticides by Wood Components

Journal of Environmental Quality, 2009
The sorption–desorption and interaction mechanisms of three non‐ionic (linuron, alachlor, and metalaxyl) and two ionic (paraquat and dicamba) pesticides by three commercial lignins (hydrophobic macromolecule) and cellulose (hydrophilic macromolecule) as wood components were studied.
