摘要

本研究对生物质样品的物理化学、结构组成和热性能进行了初步研究,以帮助适当选择用于热解操作的生物质。使用在尼日利亚夸拉州Ajasse Ipo的Ajase市场和尼日利亚夸拉县Omu Aran获得的七个木质纤维素生物质样品进行了接近、最终的结构组成和热分析。结果表明,平均含水量(MC)在0.12至0.44%之间,挥发性物质(VM)在73.70至83.82%之间。固定碳(FC)在12.79至22.80%之间,灰分在01.20至5.52%之间。同样,平均碳含量在45.11至50.00%之间。氢含量在5.38至6.15%之间,氮含量在0.20至1.24%之间,硫含量在0.01至0.19%之间,而生物质物种的平均纤维素、半纤维素和木质素含量分别在28.34至45.80%、25.83至34.01%和21.96至49.63%之间。生物质样品中记录的VM、C、H、HHV、可燃性指数、纤维素和半纤维素含量的高百分比将增强反应器中的脱挥发分反应性、可燃性和燃烧气体,以及热解过程中碳氢化合物含量的良好生产。此外,低灰分含量将防止热解过程中有害化学物质沉积在反应器中。可以推断,牛油木最适合生产生物燃料,其次是甘蔗渣和棕榈仁壳。同时,玉米芯在热解过程中具有最少的性质。

Characterization of Lignocellulosic Biomass Samples in Omu-Aran Metropolis, Kwara State, Nigeria, as Potential Fuel for Pyrolysis Yields
This study deals with a preliminary investigation of biomass samples' physicochemical, structural composition, and thermal properties to aid the appropriate selection of biomass utilized for pyrolysis operation. The proximate, ultimate, structural composition and thermal analyses were conducted using seven lignocellulose biomass samples obtained in Ajase market, Ajasse Ipo, Kwara State, Nigeria, and Omu-Aran, Kwara State, Nigeria. Results showed that the average moisture contents (MC) ranged from 0.12 to 0.44%, and volatile matter (VM) ranged from 73.70 to 83.82%. Fixed carbon (FC) varied from 12.79 to 22.80%, and Ash contents varied between 01.20 to 5.52%. Similarly, the average carbon contents ranged from 45.11 to 50.00%. Hydrogen contents ranged from 5.38 to 6.15%, nitrogen contents varied between 0.20 to 1.24%, and oxygen contents from 43.79 to 48.51%. Also, sulphur contents varied between 0.01 to 0.19%, while the biomass species' average cellulose, hemicellulose, and lignin contents ranged from 28.34 to 45.80%, 25.83 to 34.01%, and 21.96 to 49.63% respectively. The high percentage of VM, C, H, HHV, ignitability index, cellulose, and hemicellulose content recorded in the biomass samples would enhance devolatilization reactivity, ignitability, and burn gases in the reactor, as well as a good production of hydrocarbons content during the pyrolysis process. Also, the low ash content would prevent harmful chemical deposits in the reactor during the pyrolysis process. It can be deduced that shea butter wood was best suited for biofuel generation, closely followed by sugarcane bagasse and palm kernel shell. At the same time, corn cobs possessed the least properties for the pyrolysis process.
