摘要: 为研究山楂核热解特性及其产物分布规律,在不同升温速率及不同热解终温条件下对山楂核粉末进行热重分析,并用自制小型固定床热解炉对山楂核粉末进行了热解实验,考察了热解终温和升温速率对山楂核热解的三相产物产率的影响,结果表明:热解终温对焦油产率影响不大,对热解气和焦炭产率有显著影响,随着热解终温的提高,焦炭产率降低,而热解气产量增加。同一热解终温条件下,随着升温速率由5℃/min增加到10℃/min,焦油产率增加(热解终温600℃时,增加量约6个百分点),焦炭和热解气产率降低,并且热解终温越大,升温速率对焦油产率影响越大;同时,提高热解终温和升温速率会使反应速率增大。

Abstract: The pyrolysis characteristics of hawthorn kernel and its product distribution were studied by thermogravimetry experiment under different heating rate and different pyrolysis temperature with self-made fix bed pyrolysis device. The yields of the three-phase products were analyzed and the results showed that the pyrolysis temperature had little effect on the yield of the tar and had significant effect on the pyrolysis gas and the coke yield. With the increase of the pyrolysis final temperature the coke yield reduced, while pyrolysis gas production increased. Under the same pyrolysis temperature, the yield of tar increased(when the pyrolysis temperature was 600℃, the yield of tar increased about 6 percentage points) and the yields of coke and pyrolysis gas decreased with the increase of the heating rate from 5℃/min to 10℃/min, and the greater the pyrolysis temperature was, the greater the effect of the heating rate on the tar yield was. At the same time, improving pyrolysis temperature and heating rate increased the reaction rate.

Key words: hawthorn kernel, pyrolysis, thermogravimetry, tar
