In-situ supercritical methanol transesterification for production of biodiesel from jatropha curcas l. seeds / Asnida Yanti Ani

In-situ supercritical methanol transesterilication for production of biodiesel from Jairopha curcas L. (JCL) seeds was successfully carried out via 1000 ml hightemperature high-pressure hatch-wise reactor system in an absence of catalyst. In order to maximize the percent of crude biodiesel and FAME...
