In the framework of the FLEXI-GREEN FUELS project the activities of BHV focused on two closely related fields of application. Therefore, promising separation sequences were conceptualized based upon the topological analysis of the feed stream compositions produced in WP5 (the upstream work package). In a second step, attractive schemes were rigorously modelled and simulated by…

Lignin valorization is one of the key challenges for the development of economically sustainable biorefineries and fast pyrolysis holds great potential for converting lignin into high-value products. However, there are still significant challenges to overcome regarding difficulties in continuous feeding and processing of lignin in fluidized bed reactors, due to melting and agglomeration of issues.…

The main objectives of WP5 are the thermochemical/catalytic upgrading of lignin and its pyrolysis bio-oil, hemicellulose and lipids streams towards aviation and/or bunker type fuels. More specifically, AUTH research focuses on the catalytic hydrodeoxygenation of the light fraction of lignin pyrolysis bio-oil towards (alkyl)cyclohexanes which can be utilized as drop-in aviation biofuels. Furthermore, mild hydrotreatment…
