This thesis covers the process of
making Ethanol from wood biomass instead of starchy biomass. The saw dust of
Gmelina (Gmelina arborea), Eku (Brachystegia euricoma) and Mahogany(Entandrophragma cylindricum) was collected in a saw mill in Ore and used to produce ethanol by hydrolysis and fermentation processes. The density of each
of the wood species was thereafter determined as 570 kg/m3, 750 kg/cm3 and 600
kg/cm3 respectively.
The yield of ethanol from Eku, Mahogany and Gmelina wood
was determined as 50.61 g/l per 100 g of dry sawdust, 55.43 g/l per 100 g of
dry sawdust and 53.01 g/l per 100 g of dry sawdust respectively. The density of the ethanol produced from the wood of Eku, Mahogany and Gmelina was 0.8033g/cm3, 0.7088 g/cm3, and 0.8033 g/cm3 respectively. These results were
subjected to Analysis of Variance (ANOVA) and compared with conventional
ethanol.
