In this work, APBO and its typical organic matter (HAc, Phenol, Guaiacol) were used to pretreat wheat straw separately, and CFP characteristics of wheat straw before and after the pretreatment were investigated. Washing with four different solutions removed more than 95% of K(+ )and over 86% removal of Na+; the removal effect of APBO on Ca2+ and Mg2+ is more evident with more than 84%. Washing reduced AAEMs, thereby reducing acids and ketones and increasing sugars in the bio-oil. TGA demonstrated that different washing significantly increased wheat straw's maximum weight loss rate and overall ...
