Biocrude
Biocrude, also referred to as pyrolysis oil, is obtained through pyrolysis of biomass with temperatures at around 500°C. The obtained pyrolysis oil contains of a wide range of chemical compounds, including carboxylic acid, aldehydes and ketones. The quality of the produced pyrolysis oil depends on the thermal conditions and the used catalysts.
Due to the pyrolysis process the biomass is converted into solid and liquid carbon compounds. The amount of water and oxygen is also crucial for the process. Prior to appropriate treatment the pyrolysis oil shows a water content of 20 to 30%, therefore it can only be burned in large diesel stationary engines. The removal of water and oxygen is managed through a treatment with hydrogen, afterwards also the usage as vehicle fuel is possible.
