摘要: This paper reports an investigation on low-temperature oxidation prior to the ignition of biomass char from slow pyrolysis with a focus impact inorganic matter. A set chars was produced cornstalk, cellulose, and their pretreated samples (water-leached cornstalk KCl-doped cellulose) at 500 °C. The data for simultaneous thermogravimetric analysis differential scanning calorimetry isothermal showed that presence active matter, particularly K, in raw materials enhances reactivity favors heat generation chars. These observations further suggest water leaching remove species may be effective strategy reduce self-heating tendency char. situ diffuse reflectance infrared Fourier transform spectroscopy results indicated provide sites overtaking aliphatic C–H O–H sites...
