“Furthermore, the effect of potassium on the pyrolysis of cellulose and xylan was stronger than that on lignin pyrolysis.”
“On the other hand, potassium presented a promotion effect on the formation of char for cellulose but a suppression effect for lignin.”
“The results showed that potassium accelerated the start of the main pyrolysis stage of the biomass components, reduced the weight loss rate for cellulose and lignin, and increased the weight loss rate for xylan.”
