Torrefaction of biomass can reduce its undesirable properties\ for the subsequent thermochemical application. After separating a Chinese\ corn stalk into four parts (leaf, stem, root, and cob), torrefaction was\ performed at temperatures of 200, 250, and 300 {\textdegree}C respectively. The\ structural and components differences of various parts were analyzed,\ along with the solid, gas, and liquid products. The study showed that the\ root was the most sensitive to heat and the cob showed the biggest\ increase in CO2 and CO yields with the increase temperature, due to their\ different content of hemicellulose and cellulose. The torrefaction\ temperature of 250 {\textdegree}C was especially significant for the formation of\ acids. Liquid product from the leaf was simpler in composition and lower\ in yield due to higher content of organic extractives and ash. Generally,\ various parts have different torrefaction properties due to the\ differences in chemical composition and cellular structure. And with the\ thermochemical application of biomass were more widely used in the\ chemical industry especially fine chemical industry, screening and\ classification may be necessary.
