Abstract

Abstract The thermal stability of Abuja’s municipal solid waste has been investigated in this study. Thermogravimetric and differential thermal analyses (TGA and DTA) were carried out on the MSW samples from three selected districts of Abuja metropolis under nitrogen atmosphere. The TG curves for samples from Lugbe and Dutse-Alhaji market are observed to have the same thermal behavioural trends which may be due to the presence of structural similarity of substances contained in the two samples compared to the behaviour of sample from Galadimawa district. It was observed that Galadimawa sample exhibited two stages of decomposition while Lugbe and Dutse-Alhaji samples have three main stages of decomposition. This study reveals that Abuja’s MSW have endothermic temperature peaks of 405.75 oC for sample from Lugbe district, 409.51 oC for Galadimawa district sample and 381.42 oC for sample taken from Dutse-Alhaji market, respectively. These values compare well with corresponding values for Nigerian coals (Enugu with 408 oC), thereby showing good thermal stability, and will be better and more economic fuel for energy generation than coal in addition to being renewable.

阿布贾城市固体废物作为可再生能源的热稳定性研究

摘要本文研究了阿布贾城市生活垃圾的热稳定性。采用热重分析和差热分析(TGA和DTA)对尼日利亚首都阿布贾3个地区的生活垃圾样品进行了氮气氛下的分析。Lugbe和duts - alhaji市场样品的热重曲线具有相同的热行为趋势，这可能是由于与Galadimawa地区样品的行为相比，两个样品中所含物质的结构相似。结果表明，Galadimawa样品呈现两个分解阶段，Lugbe和Dutse-Alhaji样品呈现三个主要分解阶段。研究表明，阿布贾城市生活垃圾Lugbe区、Galadimawa区和duts - alhaji市场的吸热温度峰值分别为405.75 oC、409.51 oC和381.42 oC。这些值与尼日利亚煤(Enugu煤，408℃)的对应值比较好，因此表现出良好的热稳定性，除了可再生外，还将是比煤炭更好、更经济的能源发电燃料。
