Lignocellulosic feed is expected to contribute significantly to production of liquified and solid combustibles in future, because of the quantity and the variety of feed material. The aim of the project is the production of high-quality biochar and a liquid energy carrier in a non-aqueous hydrocarbon-based pyrolysis system. Therefore, the pyrolytic(More)
The aim of the present work was to improve the C:O ratio in biomass by preserving the lignin macrostructure of lignocellulosic feed. The intention of liquid phase pyrolysis is to liquefy biomass and prepare biomass for further upgrading steps like hydrogenation and deoxygenation. Pyrolysis was carried out in a non-aqueous liquid phase heat carrier. The(More)
Second generation biofuels, especially fuels from lignocellulose biomass, which are manufactured from non-food feedstock play a key role to reduce greenhouse gas emissions and the dependency on fossil oil. The bioCRACK process represents a new biomass-to-liquid concept to generate advanced biofuel by liquid-phase pyrolysis. As liquid heat carrier vacuum gas(More)
The bioCRACK process can convert as much as 18 percent of biomass into fuel intermediates for diesel production. This process was operated in pilot scale over two years. Beside fuel intermediates, pyrolysis oil is formed in the bioCRACK process. In the second technology development step pyrolysis oil was upgraded by continuous hydrodeoxygenation in lab(More)
The renewable resource pyrolysis char hereinafter often referred to as biochar, produced by pyrolysis or hydrothermal carbonization, has promising properties for advanced upgrade. Technologies for the conversion of biochar to biofuels may therefore contribute to suffice the growing demand for fuel. Direct liquefaction of biochar is a conceivable way of(More)
