Carbon formation may occur during CO2 and CO2/H2O electrolysis using solid oxide electrolyzer cells due to the Boudouard reaction (2CO → CO2 + C(s)). Formed carbon may disintegrate the cell structure and it is therefore of importance to be able to

Loosely packed biomass dusts may self-heat and spontaneously ignite, especially when kept under elevated temperatures as in power plant mills. In this work, a mechanistic model was developed to predict self-ignition of biomass under such conditions.

An attractive option for reducing the net CO 2 emissions is to substitute coal with biomass in large power plant boilers. However, the presence of chlorine (Cl) and alkali metals (K, Na) in biomass may induce large operational problems due to ash dep
