Investigation of enzyme-catalyzed transesterification of used frying oils
Investigation of the possibility to convert used frying oils to less harmful but more valuable products is driven by the protection of environment and human health as well as economical reasons. One solution could be the conversion of these oils to transportation fuels and their application in Diese...
