Summary:

In the search for sustainable transportation fuels that are not in competition with food production, considerable efforts are made in the development of so-called second-generation (2G) biofuels. This paper looks into the results of a novel 2G biofuel production technique that is based on a catalytic process that operates at low temperature and that converts woody biomass feedstock into a stable light naphtha. The process development is integrated in the Belgian federal government funded Ad-Libio project and the process outcome is mainly consisting of hydrocarbons containing five to six carbon atoms. Their composition can be altered, resulting in a large amount of different possible fuel blends. The ultimate goal is to produce a drop-in fuel that can be fully interchanged with the gasoline fuels in use today. This is a challenge, since the Ad-Libio fuel components differ significantly from gasoline fuel components. For an initial assessment of the suitability of a novel blend, a fuel blend calculator with integrated fuel database has been developed. This tool enables fast SI fuel property calculations, so quick decisions can be made on the fuel production process outcome. The blend's research octane number (RON) is one of the important properties to be checked for a blend's suitability as a spark ignition engine fuel. After a first screening with the calculator, the average peak pressure pulsation (APPP) method was used on a CFR engine to evaluate the octane number of the blends, enabling quick in-house experimental octane number verification of the calculations before the blends can ultimately be sent to an ASTM-compliant testing laboratory.This article describes the calculation and verification methodology of the first blends that have been used to design a new and fully sustainable SI engine fuel blend, ultimately aiming for a sustainable second-generation drop-in gasoline fuel replacement
