Abstract
The large scale of manufacturing and advanced technical enterprises has led to a rising deficit of traditional fossil fuels and a severe energy and environmental situation. To reduce the dependence on fossil fuels an extensive effort has been focused to develop a sustainable and green energy resource. This research will investigate and report on the possibility of generating Nanoparticles from the lignocellulosic biomass (Bagasse) using conventional manufactured ball milling equipment under standard temperature and pressure. The result of grinding process consists of different ball sizes and different milling intermissions. The analyses of the literature by way of it related to mechanical pretreatment and characterisation of biomass (Bagasse) for different pretreatment approaches. Lignocellulosic Biomass (Bagasse) has a potential to produce Bio-ethanol; however, the pretreatment methods are expensive. This investigation focuses on the effective transformation of bagasse for the pretreatment method. The conventional mechanical pretreatment method is used to produce Nanoparticles for a better fermentation process to make the production of Bio-Ethanol more efficient. The bagasse sample of 0.5 grams is observed from the manufactured vertical ball milling equipment for different time intervals. The samples are centrifuged and analysed in the PAMAS-S-40 particle analysing equipment to determine the particle size and particle count for the different time intervals. Scanning Electron Microscopy (SEM) was used to characterise the morphology of bagasse fibres. Samples were gold coated using smart coater and observed in the SEM to characterise the samples in different time intervals. The results concluded that Nanoparticles of bagasse can be produced using the Conventional Ball milling method and a higher nanoparticle percentage can be attained from greater hours of ball-milling time with different sizes of grinding balls. It is evident from the calculation that the nanoparticle percentage increased from 25.8% (30 minutes) to 35.8% (4 hours).
