Abstract: Under the background of "Carbon peaking and Carbon Neutrality", the emission reduction of aviation industry can be achieved by blending withSustainable Aviation Fuels (SAF). In the SAF production route, the technology of biomass gasification synthesis to SAF has been widely concerned around the world in recent years for its advantages such as feed adaptability. However, moving bed or fluidized bed biomass gasification technology will produce tar much more difficult to remove than similar gasification technologies, which will have a great impact on the long-term operation and economic benefits of the plant. This article reviews the tar treatment technology in the production of SAF from biomass gasification, and studied the impact of different tar treatment technologies on the overall configuration. By comparing the advantages and disadvantages of different tar treatment technologies, the role of these technologies in the overall configuration is studied. Finally, the technical route and tar treatment technology are summarized and prospected, and targeted suggestions are put forward in order to provide new ideas for the overall process planning of biomass gasification to SAF in the future.

Key words: sustainable aviation fuels, tar treatment, overall configuration
