Effect of Inorganic Salts on Product Composition During Pyrolysis of Black Spruce
Keywords:Black spruce, pyrolysis, inorganic salts
The effect of inorganic salts on the pyrolysis of black spruce sawdust was determined in the temperature range 400-500 C under 2-mm Hg vacuum.
The major pyrolysis products were: a char residue; light and heavy liquid fractions; volatiles (CH4, C2H4, C2H6, and C3H6); and gases (H2, CO, and CO2). Experiments on untreated and treated sawdust show that salts reduce the proportion of flammable tars, volatiles and gases, and increase the proportion of char.
