Introduction

The Cooperation Agreement between the Ministry of the Environment and the CNR, ENEA and AM bodies, regarding the production of biofuels and their use in the aviation sector, it is intended to acquire and process, also through experimental activities, data scientific and technical experts on the efficiency and environmental impact of the production and use of biofuel in the aviation sector.

Description

For the purposes of the Agreement, the collaboration of the parties in the following research and experimentation activities is as follows:
a. Alternative fuel sources that meet the need for aviation sector engine performance suitable in terms of efficiency and sustainability, also with reference to the evaluation of vegetable matrices suitable for the production of biofuels and the economic and environmental sustainability of the production of biofuels for aerotraction;
b. Technologies for verifying the correctness of the declared values ​​of bio-fossil fractions, so as to discriminate with certainty the fractions from fossil sources from the biogenic ones;
c. Analysis of the composition of biofuels by aviation, in terms of comparison of the performances and emissions produced by their combustion, also with reference to micropollutants;
d. Advanced technologies for the conversion of biomass into sustainable products suitable for the purpose of the aviation sector such as biofuels;
is. Chemical-physical characterization of the identified biofuels;
f. Optimization of the injection parameters of aviation biofuels (pressure, type of nozzle) during use;
g. Evaluation of the engine performance ensured by aviation biofuel compared to that guaranteed by fossil fuels;
h. Analysis of the correspondence of national and international specifications relating to aviation fuels;
the. Evaluation of the interaction between aviation biofuels with metallic and polymeric materials present inside the engines, also with reference to any significant alterations that reduce the useful life of the engines themselves.

Objectives

The main objective is the analysis of biofuels for aerotraction in terms of composition, performance and pollution.
The characterization, from the point of view of the certification of the bio / fossil fraction, of the efficiency assessment and of the study of the environmental impact, of aviation biofuels is essential to understand if the large-scale diffusion of this new type of fuel is advantageous and desirable for the reduction of greenhouse gas emissions. The research team that will collaborate for the realization of this Project contains in itself complementary synergistic skills for the achievement of this objective, through a series of sub-objectives, listed below.
Ø Development of an instrument, based on radiocarbon optical detection (SCAR), for the analysis of the bio / fossil fraction in biofuels.
Ø Creation of a system for the preparation of the CO2 sample to be analyzed.
Ø Analysis of the composition of biofuels for aerotraction
Ø Analysis of the pollution produced by combustion
Ø Identification of the biofuels to be characterized Characterization of the properties of the individual drops of biofuels
Ø Characterization in isothermal conditions of the biofuel spray
Ø Combustion characterization of biofuels
Ø Development of a system for the chemical characterization of biofuels in aeronautics
Ø Dissemination / promotion for the use and production of biofuels in Italy
