Abstract [en]

Being an oil - rich country, Nigeria’s energy supply is primarily fossil - based. The unequal distribu - tion of oil wealth, along with agitation for self - determination and resource control, has led to the sabotage of oil installations. This, in turn, has affected all services running on the energy supply from these installations, leading to incessant or total sh ut - down of such facilities. Power generated using biomass - based renewable energy technologies is a promising option in limiting the coun - try’s dependence on fossil energy for power generation. The most important part of this option is on - site power generation via mini - grid systems. The power thus produced is utilized with the excess being fed into the national grid based on Feed - in - Tariff (F.i.T.) requirements and techni - calities. The important factors to be considered in the propagation of a mini - g rid option are ex - amined in this study. Furthermore, the study shows that about 1.3 TWh of electricity can be gener - ated from the 1.8 million tonnes per year of wood waste produced by the lumber industry in Nige - ria. Power generation through the utiliza tion of biomass has however proved to be a possible path in achieving economic, social and environmental sustainability in the country. Economic studies show that for small - scale power generation, internal combustion engines and Stirling engines are econom ically feasible. Steam turbines and gas turbines are mostly used in medium/large - scale biomass power generators, especially in proximity to biomass waste resources. Micro gas turbine power technology can also be applied on a small scale despite its high to tal investment capital.

Abstract [en]

The utilization of wood biomass for energy recovery purposes is a phenomenon that is increasingly attracting attentions from researchers, companies and countries all over the world. The effect of climate change as largely represented by global warming leading to glacier ice melting and an unprecedented rise in sea level is a worrisome development. One of the causal agents of this scenario is the increase in world’s greenhouse gas emission. A sure method of approach to ending the problem is to drastically reduce the emission level to the barest minimum, or to zero level if possible. Wood biomass conversion via thermal treatment is an activity capable of reducing the emission possibility as the CO2 released during the conversion is effectively taken care of. Another benefit derivable from the conversion is taking care of what otherwise would have been termed a waste and treated as such. The envisaged use of wood resource to solve the lingering power problem in Nigeria is an effort in the right direction.

The thesis highlights the conversion processes, as well as the reaction kinetics involved. Reaction parameters such as temperature, heating rate, partial pressure, and flow rate were investigated for the purpose of identifying their effect on the conversion processes. The typical kinetic parameters obtained during the conversion processes would be of high importance in the design and configuration of reactors meant for the optimum conversion of wood waste biomass as a valuable resource. With the non-tropical wood biomass already deployed for energy conversion in the developed countries, the similarity in the trend as regards conversion reactions (char formation and

conversions, kinetic parameters) compared to the tropical counterpart is a welcome development. This suggests the candidacy of non-tropical wood biomass for energy recovery purposes as a viable one.
