| Tranesterification reaction was carried out on raw Shea Butter Oil (SBO) and Palm Kernel Oil (PKO) to separate the ester from glycerol using ethanol in the presence of potassium hydroxide as catalyst. The properties of biodiesel (ethyl ester) obtained from varying proportions of diesel were experimentally determined and compared with that of conventional diesel. The fatty acid profile of the oil samples were determined using standard methods. Four blends (10, 20, 25 and 30%) of SBO and PKO by volume with diesel oil were produced and fuel properties determined include viscosity, relative density, specific gravity, flash, cloud and pour points. Mean values of the six fatty acids (palmitic, stearic, oleic, linoleic) obtained for shea butter and palm kernel... |

| The study was undertaken to investigate the energy input and output of a group of citrus research farms in Nigeria. Data used in this study were collected in-situ on yearly basis; therefore the analysed and discussed energy values were averages of data collected over the years. The research results indicated that total energy inputs were 46.64 GJha-1. About 35% was generated by human labour, 38% from diesel oil and machinery, while other inputs contributed 29% of the total energy input. About 87% of the total energy inputs used in sweet orange production was from direct sources (seeds, fertilizers, manure, chemicals, machinery) and 13% was from indirect sources (human labor, diesel). Mean orange yield was about 41000 kg ha-1. The net energy and energy... |
