The forms of alkalis in the biochar produced from crop residues at different temperatures
TL;DR: The forms of alkalis of the biochars produced from the straws of canola, corn, soybean and peanut at different temperatures (300, 500 and 700°C) were studied by means of oxygen-limited pyrolysis and it was suggested that carbonates were the major alkaline components in theBiochars generated at the high temperature.
