Jatropha Curcas is a non-edible plant that can be used for renewable or alternative energy. The seeds of Jatropha contain up to 60 percent oil. The oil can be converted into biodiesel by well-known two-step using acid-base catalytic transesterification. This paper shows the combustion performance of biodiesel derived from Jatropha oil in an oil burner designed for conventional diesel. Biodiesel used in this study is a blend of diesel with Jatropha Methyl Ester (JME) and combustion performance was measured and compared with that of conventional diesel fuel (CDF). The combustion performance of Jatropha biodiesel is based on wall temperature profiles and the amount of gaseous emissions emitted such as nitrous oxide (NOx), sulphur dioxide (SO2) and carbon monoxide (CO). It was demonstrated that biodiesel derived from Jatropha is comparable to the combustion properties of CDF and has high potential to be used as alternative fuel for diesel machines.

Carbonate Species

Copper oxide modified electrodes were investigated as a function of applied electrode potential using in situ infrared spectroscopy and ex situ Raman and X-ray photoelectron spectroscopy. In deoxygenated KHCO3 electrolyte bicarbonate and carbonate species were found to adsorb to the electrode during reduction and the CuO was reduced to Cu(i) or Cu(0) species. Carbonate was incorporated into the structure and the CuO starting material was not regenerated on cycling to positive potentials. In contrast, in CO2 saturated KHCO3 solution, surface adsorption of bicarbonate and carbonate was not observed and adsorption of a carbonato-species was observed with in situ infrared spectroscopy. This species is believed to be activated, bent CO2. On cycling to negative potentials, larger reduction currents were observed in the presence of CO2; however, less of the charge could be attributed to the reduction of CuO. In the presence of CO2 CuO underwent reduction to Cu2O and potentially Cu, with no incorporation of carbonate. Under these conditions the CuO starting material could be regenerated by cycling to positive potentials.
