Specific heat and thermal conductivity of softwood bark and softwood char particles☆

Fuel, 2003
Abstract Very few data exist regarding the thermal properties of softwood bark and therein derived softwood chars. This work describes the measurement of specific heat and particle thermal conductivity of softwood (SW), softwood bark (SB) and therein derived softwood char (SC). Differential scanning calorimetery (DSC) was used to measure the specific

Solubility of Softwood Hemicelluloses

Biomacromolecules, 2018
It is demonstrated that the molecular solubility of softwood hemicelluloses is significantly influenced by pretreatment of the fibers, extraction, and downstream processing. To quantify these effects, four hemicellulose samples were extracted from different thermomechanical pulps of Norway spruce.

Clonal Propagation of Softwoods

2005
Softwoods or gymnosperms, which make up 60% of the forested areas of the world, are economically important as a source of lumber, pulp, and paper. Reforestation is a major activity worldwide and the potential benefits of using clonal planting stock have long been recognized. Tissue culture clonal methods or micropropagation is a newer approach that can

SOFTWOOD COMPOSITES FOR CONSTRUCTION

Materials of the All-Russian scientific and practical conference "Modern machines, equipment and IT solutions for industrial complex: theory and practice", 2021
The article deals with the issues of secondary use of industrial waste from the processing of soft hardwood wood. It is shown that the disposal of man-made waste in landfills is undesirable, and the use of wood waste to generate heat for heating is limited to the autumn-winter period.

Pyrolysis kinetics and product properties of softwoods, hardwoods, and the nut shell of softwood

Korean Journal of Chemical Engineering, 2016
The pyrolysis of softwoods (Pinus (P.) densiflora, P. koraiensis), hardwoods (Quercus acutissima and Liriodendron tulipifera) and nut shell of P. koraiensis was investigated using a thermogravimetric analyzer and fixed bed reactor. Thermogravimetric analysis showed that the maximum decomposition temperature of each biomass was influenced by the ash ...
