Knowledge contribution from science to technology in the conceptualization model to produce sustainable aviation fuels from lignocellulosic biomass

Alternative biofuels provide a great perspective to assist the fast decarbonization of the mobility area and replacement for conventional non-renewable petroleum fuels. Sustainable aviation fuels (SAF) as a fuel in the aviation sector are presently generated from several raw materials and conversion passages to fulfill sustainability goals. In this article, using modeling systems, the material balance for generating sustainable aviation fuel utilizing PCH (pyrolysis, coking, and hydrocracking) technologies from lignocellulosic biomass is presented. According to the technology, bio-raw materials (sawdust and husks) are subjected to rapid pyrolysis at the first stage. The second stage is the delayed coking of mixed raw materials containing up to 25 wt % of biooil. The resulting coking distillates, mainly gas oils, are sent to hydrocracking, where high quality fuel components are produced. According to the material balance, the kerosene component in its composition contains about 5 wt % of organic kerosene. The results reported that an innovative SAF generation pathway has been currently upgraded, which depended on lignocellulosic biomass.
