摘要:

为探讨沿海绿潮藻类浒苔的资源化利用潜力,应用热重-差示扫描量热技术(TG-DSC)对条浒苔(Enteromorpha compressa)和玉米(Zea mays)秸秆的热解特性及其在不同温度下制成的生物炭的性质进行对比。结果表明,条浒苔与玉米秸秆热解特性有较大差异,条浒苔热稳定性较差,热解反应温度低,制备相同热解温度的生物炭需热量较少。对2种材料所制备生物炭的性质分析表明,条浒苔基生物炭的w(碳)为33.47%~37.86%,仅为玉米秸秆基生物炭含量的49.07%~65.41%,其芳香化合程度、比表面积均低于相同热解温度下玉米秸秆基生物炭;但条浒苔基生物炭灰分和氮含量却远高于玉米秸秆基生物炭,分别是玉米秸秆基生物炭的3.83~4.53和6.39~30.33倍。

Abstract:

In order to explore potential of the algae to be used as resource, researches were done to determine pyrolytic feature of algae(Enteromorpha compressa) and cornstalk(Zea mays) with the technology of differential scanning calorimetry & thermo-gravimetric analysis (TG-DSC)and compare their pyrolysis products of biochar under different temperatures (350, 500 and 650 ℃) in property. Results show that the two materials differed sharply in pyrolytic feature. The algae are quite low in thermo-stability and pyrolytic reaction temperature, so they do not need so much heat as cornstalk does to get pyrolyzed into biochars at the same set temperature. Analysis of properties of the biochars prepared out of the algae and cornstalk shows that the biochar of algae was 33.47%-37.86% in carbon content, equaling to 49.07%-65.41% of the carbon content in the biochar of cornstalk, and also lower in specific surface area and aromatization degree than the biochar of cornstalk. However, the former was far too much higher than the latter in ash content and nitrogen content or 3.83-4.53 and 3.38-30.33 times as high as the latter.
