The liquid engine fuels are the main power source of the transportation in the passenger sector. Within this, the waste originated engine fuels can play the main role to achieve the prediction of EU, to reach the 10 % ratio of the renewable fuels until 2020. Thus the sustainable and environmental friendly production of this components is momentous. To achieve all this goals the European Union created the 2003/30/EC and further the 2009/28/EC Directives to encourage the bio components blending

The main reason is the demand for better quality fuels and wider raw material basis. All of these above mentioned reasons explain the investigation of unconventional feedstocks which do not endanger the security of food supplement and/or can be processed with lower operation costs. For example these feedstocks can be non-edible hybrids such as rapeseed oils with high euric acid content obtained from special hybrids of rape (e.g. Brassica Napus) or high oleic acid containing oil sunflowers (Saaten Union Capella) waste lards (used cooking oil, slaughterhouse lards) or raw materials from long term unused agricultural area (abandoned area). The precondition of availability is the sustainable and the technical compatibility with running engine and vehicle construction, thus this bio components can be blended in the motor fuels unlimited quantity. Considering the utilization properties of currently used first generation biofuels, the maximum amount of biocomponent in the applied motor is 10% bioethanol in the case of gasoline and 7 % fatty acid methyl ester in the case of diesel fuels. One of the reliable production technology of second generation biofules which can be blended into diesel fuels is the heterogenic catalytic hydrogenation of triglycerides and waste lards. In this context we studied the heterogeneous catalytic hydrogenation of used cooking oils on aluminium-oxide support [...]
