Abstract

Studies were conducted to establish baseline information for use in characterizing Siberian elm as energy or fiber feedstock. Biomass properties were determined. Calorific value (4,698 cal/g) and specific gravity (0.55) of Siberian elm are similar to those of soft elms, and its fiber length is relatively short (1.00 mm). Ash content was 1.65%. Gasification produces a medium energy gas (3 x 106 cal/m3) with yield varying from 0.17 to 0.96 m3/kg over a gasification temperature range of 600 to 700 C. Ovendry yields were 9.8 t/ha annually at 700 trees/ha.
