The elemental composition was determined
by an elemental analyzer (Fisons, Germany; Model: EA 1108) in the Department
of Chemistry at the University of British Columbia. The chemical
composition of control wood pellets was measured by
FPInnovations using a high-performance liquid chromatography
(Dionex Corporation, USA; Model: ICS-3000 Ion Chromatography System)
following the ASTM E1758-01 procedure [12]. The chemical composition
of two commercial wood pellets was measured by the
University of Science and Technology Beijing using a liquid chromatography
(Shimadzu, Japan; Model: LC-20AT) following the ASTM E1758-
01 procedure. From Table 1, it can be seen that the properties of both
the control wood pellets and the white commercial wood pellets were
very similar. The HHV and the ash content of the brown commercial
wood pelletswere slightly higher than thewhite commercialwood pellets
and the controlwood pellets because of the high bark content in the
raw material of the brown commercial wood pellets
Compensated Calorimeter). The volatile matter, fixed carbon, and ash
content were measured by a thermogravimetry analyzer (Shimadzu,
Japan; Model: TGA-50).
