Emission of pollutants from torrefaction of wood / Emília Hroncová, Juraj Ladomerský, Jozef Puskajler. -- The torrefaction of biomass is carried out in order to obtain homogenous material with a low water content. This process can also be called mild pyrolysis. The paper focuses upon an experimental study of emissions released in the torrefaction process of deciduous wood types beech (Fagus sylvatica) and linden (Tilia cordata). Torrefaction was carried out in a reactor from Parr Instrument Company, USA. The reactor was heated to a temperature of 300ºC which was maintained for three hours. Concentrations of pollutants CO, CO2 and CH4 were ascertained in the emissions. For beech, concentrations of CO and CH4 increased with temperature up to a concentration of 12500 ppm and 2.59% at a temperature of 300ºC. For linden, concentrations of CO2 decreased with increasing temperature to 2.63% at a temperature of 300ºC
