- 摘要:
- 秸秆的综合利用日益受到关注,为利用轻度炭化技术制备的生物炭以提高玉米秸秆的燃烧值,降低其运输、储存成本,采用微分热重分析仪(DTG)研究了轻度炭化的玉米秸秆生物炭的燃烧行为。结果表明:通过TG-DTG三点法得到生物炭的燃烧点为303.89 ℃。利用Arrhenius方程,可知玉米秸秆生物炭的燃烧为一级反应,活化能为35.45 kJ·mol-1。
- Abstract:
- The comprehensive utilization of maize stalk efficiently has been more and more attention.It is costly to collect,store and transport maize stalk because of its high water content,low density and perishable properties.Incompletely carbonization method was invented to produce biochar in order to solve above problems.The combustion behavior was studied by a thermal gravimetric analyzer (DTG).The results showed that the combustion point was obtained by TG-DTG curve which was 303.89 ℃.According to Arrhenius equation,combustion process of biochar followed the first-order kinetic equation and the activation energy of combustion was 35.45 kJ·mol-1.
