在大多数南亚国家，农业副产品和木材工业废料是主要的生物质固体废物。利用这些废弃物来提高能量回收率，可以实现巨大的节能。热解是一种热化学转化过程，已被认为是从有机固体废物中生产液体燃料的最有竞争力的方法之一。为此，对固体废物特性的研究对于选择合适的原料以及设计和建造合适的热转化系统至关重要。在这项研究中，已经进行了调查的本地可用的农业副产品：稻草，黄麻棒和甘蔗渣的特性。该主要表征包括物理性质、工业分析、元素分析、热值和热重分析（TGA）。这些废物的物理特性，如粒度分布和堆积密度已被考虑。元素分析的元素组成，在碳，氢，氮，氧和硫（CHNOS）的含量方面的选定的生物质进行了测定。通过热重分析（TGA）获得所选固体废物的热特性。研究发现，稻草、黄麻和甘蔗渣是转化为液体燃料的良好原料。还发现，为所选生物质设计的转化系统的操作温度范围为300至600 ℃。因此，可以使用这些进料材料进行进一步的热解研究。
In most of the south Asian countries agricultural by-products and waste of wood industries are the major biomass solid wastes. Utilizing these wastes for improved energy recovery a tremendous energy saving could be realized. Pyrolysis, a thermochemical conversion process has been projected as one of the most competitive ways of producing liquid fuel from organic solid waste. For this purpose studies on the characteristics of solid wastes are essential in selecting suitable feedstocks as well as in the design and construction of a suitable thermal conversion system. In this study investigations have been conducted on the characterization of locally available agricultural by-products: rice-straw, jute-stick and bagasse. This primary characterization included the physical properties, proximate analysis, elemental analysis, calorific value and thermogravimetric analysis (TGA). The physical characteristic of these wastes such as particle size distribution and bulk density have been considered. The elemental composition by ultimate analysis, in terms of carbon, hydrogen, nitrogen, oxygen and sulfur (CHNOS) content of the selected biomass was determined. The thermal characteristics of the selected solid wastes were obtained by thermogravimetric analysis (TGA). From these studies it is found that rice-straw, jutestick and bagasse are good feedstocks for conversion to get liquid fuel. It is also found that the operating temperature range of the conversion system to be designed for the selected biomass is 300 to 600C. Thus, further pyrolysis studies may be proceeded using these feed materials.
