Webb1 okt. 2024 · K is linked to corn straw mainly through COO- group, and Ca is linked to corn straw mainly through C–O group. Both K/Ca elements are effective in inhibiting the consumption of C–O–C group during corn straw pyrolysis. Besides, K element can catalyze the depletion and decomposition of C–O group during pyrolysis. Webb29 juni 2007 · The content of Ca and K was also reduced by the salt treatment. However, the content of Na was increased. Treatment with Rs-5 could reverse the results. Na + content in Rs-5-S decreased by 29.5% compared to CK-S. Ca 2+ and K + contents in Rs-5-S increased by 30.5 and 9.5% compared to CK-S, respectively.
