Biomass technologies have become an important approach to meet the current demand of energy. Pyrolysis is one of the promising technology to convert varied types of biogenic wastes into biofuels, which also may gradually be replacing the crude-oil resources. The To-Syn-Fuel project has a great potential to valorization of a high variety of biomass into biofuels including H2-rich synthesis gas, biochar and a bio-oil that can be upgraded to green liquid fuels to be applied directly in engines. The aim of the To-Syn-Fuel project is to demonstrate the conversion of sewage sludge to EN conform diesel and gasoline. The main technology of the project is the TCR® process converting the sewage sludge into thermal stable crude bio-oil and hydrogen-rich TCR® gas. Both are the precursor for the EN diesel and gasoline. The midterm aim is to demonstrate the applicability of the TCR® crude-oil to refineries. Thereby, the already existing logistic infrastructure of fossil fuels could be used for processing and distributing green fuels.The aim of this abstract is to introduce the EU project To-Syn-Fuel and to show its novelty in terms of the generation of green, EN conform fuels. The To-Syn-Fuel project is an integration of three technologies, the Thermo-Catalytic Reforming TCR®, hydrodeoxygenation (HDO) and pressure swing adsorption (PSA). TCR® is the main process in the system, which it is developed by Fraunhofer UMSICHT. It is a combination of intermediate pyrolysis at mild heating rates followed by a catalytic reforming step at a high temperature range of 500°C to 700°C. The TCR® process shows a great potential for the To-Syn-Fuel project, whereas it produces high quality of bio-oil with low O/C ratio and low water content, which makes it ready to be upgraded in the HDO process. In addition to, it provides engine-ready gas with high hydrogen concentration up to 40vol.% and it is directly suitable for hydrogen separation by the PSA process. The unique selling point of the TCR® products is the thermal stability of the oil, which enables high temperature upgrading processes like e.g. distillation or hydration, which is carried out within the To-Syn-Fuel project.
