D3.10 Method development and validation of PAH13

In view of the production of large quantities of fast pyrolysis bio-oil (FPBO) and the use of these oils in various applications, the FBPO should have a REACH (Registration, Evaluation and Authorization of Chemicals) registration according to European legislation. Within the REACH registration a SIP (Substance Identity Profile) is incorporated giving amongst other things the maximum allowable concentration of certain components in the FPBO. Large quantities (> 1000 kg/y) of pyrolysis liquids can only be produced and traded as FPBO if they meet the criteria given in this registration. Furthermore in the REACH registration, an EU producer should indicate if a substance is toxic (and to what extend) and how this substance should be handled safely by e.g. the user. So in view of the application of various pyrolysis liquids as boiler fuels (FPBO’s) in this project, this would of course be of great importance. One of the component groups mentioned in the SIP are the PAH’s (poly aromatic hydrocarbons). PAH’s are notorious of having carcinogenic and/or mutagenic effects on the human body, and allowable concentration are therefore very low. Due to the general complexity of the FPBO, it is difficult to apply standard methods e.g. used in PAH’s analysis of water and mineral oils samples. The alternative analytical methods that were applied to determine the PAH’s in FPBO were however not yet properly evaluated. This deliverable describes the development and validation of a method suitable for qualification and quantification of the PAH’s in FPBO. FPBO samples were analysed by 3 different laboratories and compared mutually and with data obtained in the earlier BIOTOX project for method evaluation. This method validation was to a large extend already performed in earlier projects (Empyro & Pyrobest). In this deliverable the analysis and results of these separate tests are combined, compared and evaluated. Actual analysis of Residue2Heat samples will be carried out soon, and reported separately.
