The char yield
網頁2024年5月12日 · The reduction in char yield is attributed to secondary repolymerisation reactions []. When the temperature is changed from 350°C to 550°C, the yield of liquid oil changes from 62.4 wt% to 69.4 wt% and the maximum yield … 網頁2024年6月24日 · The tar yield had slight decrease when char temperature was below 400 C, while obvious decrease in tar yield was observed when char temperature was above 500 C, especially for 700–900 C. With char temperature increased from 100 to 900 °C, the light oil content and light oil yield first increased and then decreased.

網頁Abstract. Pyrolysis is the initial stage in both gasification and combustion of biomass. The treatment conditions in the pyrolysis determine the char yield and its reactivity in the gasification. The experimental equipment used in this work for the rapid pyrolysis of wood is a pressurized free-fall reactor. The rapid pyrolysis is performed at ... 網頁The use of high-char resins is one approach to producing larger bundles. However, the resin systems that currently provide the best composite mechanical properties are the epoxies, and these have low char yields. The high-char-yield resins generally are more
