Branch wood, as a renewable biomass resource, presents certain challenges due to its high volume, complex physical properties, difficulty in handling, and relatively production costs. Potassium chloride (KCl) treatments were applied ash branch wood (ABW) using solutions with concentrations of 5%, 10%, 15% via immersion. Pyrolysis tests performed at different pyrolysis temperatures (450 °C, 600 750 °C) times (2 h, 3 4 h). The thermal degradation behavior was meticulously examined through Thermogravimetric Analysis (TGA). Furthermore, the kinetics assessed Flynn–Wall–Ozawa (FWO) model, which allowed for determination kinetic parameters exploration catalytic influence KCl on process. morphology adsorption properties biochar evaluated employing SEM-EDS BET characterization methods, respectively. results show that higher impregnation concentration ABW, greater shift TG DTG curves, lower initial temperature maximum weight loss devolatilization stage. calculation indicates adding ABW activation energy volatile phase ABW. At same time, leads an increased yield; under single-factor conditions, yield up 35.81% can be achieved 15%. A is more conducive reaction, throughout stage compared raw Additionally, treated low specific surface area pore volume biochar. values are when solution 4.2 m2/g 0.00914 cm3/g. Based these results, this paper explores patterns waste, providing theoretical guidance effective utilization preparation process
