Biomass is the only renewable energy source with carbon, and it is an ideal raw material for preparing liquid fuels, materials, chemicals, and other carbon containing products in the era of carbon neutrality. Biomass pyrolysis and gasification is an effective way to obtain high-value products mentioned above on a large scale. However, traditional pyrolysis and gasification obtains primary products first, and then develops to obtain high-value products. Due to the long process flow, low target product yield, poor economy, it is difficult to achieve industrialization.  This report focuses on a novel high-value system for biomass directed pyrolysis and gasification, in which intermediate products are purified online and in situ, and liquid fuels, carbon materials, and hydrogen can also be prepared through a short process. In addition, this report will also present biomass directed pyrolysis and gasification, short and integrated processes, and integrated reactors.
