METHOD FOR PRODUCING PYROLYSIS GAS OR PYROLYSIS OIL FROM BIOGENIC STARING MATERIALS AND PYROLYSIS OIL, PYROLYSIS GAS AND DEOXYGENATION CATALYSTS THAT CAN BE PRODUCED BY MEANS OF SAID METHOD

摘要

A method is described for producing pyrolysis gas and pyrolysis oil from biogenic starting materials. First, a biogenic starting material, selected from ligncocellulosic biomass and lignocellulosic residual substances, and a carbon-based catalyst are provided. The starting material is then thermally treated in a pyrolysis reactor at a temperature T1 to effect pyrolysis of the starting material to liquid, vaporous or gaseous pyrolysis products. These pyrolysis products are then brought into contact with the carbon-based catalyst at a temperature T2 so that deoxygenation of the pyrolysis products to at least partially deoxygenated pyrolysis products occurs. These products are then collected in a separation device in which product separation takes place. In addition to liquid or gaseous pyrolysis products, catalysts that can be used for deoxygenation are also described which can be produced from the solid material that was separated following pyrolysis.
