Abstract:

The emerging biofuels sector enjoys presently a strong growth, while new biomass­to­biofuels pathways are leading rapidly to third­ and fourth­generation sustainable solutions. The change to renewable energy, however, is not an easy task; besides the technical challenges, there remain key considerations about the lack of appropriate quality standards. Most of the standards developed for biofuels, as the EN14214:2003, are drawn from the assessment of petrofuels, despite the distinct differences between biomass­derived fuel chemistry and petrochemistry. As a result, the standard methodology often fails, in the sense that the product can nominally comply to specifications but falls short of performance. This work presents a knowledge­based approach for extending EN14214 to cover the specific biofuels chemistry by means of constructing the network of paths (along with their intra­ and inter relations) for both, fuel and impurities, throughout the whole value chain (bottom­up analysis), based on information provided by fault tree analysis (in its fuzzy version to count for uncertainty) used herein to identify the sources of the analytical issues that have been reported for end products (top­down analysis). This approach has been implemented for the oxidation stability protocol, one of the most pressing measurement challenges in the assessment of biodiesel quality.
