A reduced n-dodecane-polycyclic aromatic hydrocarbon (PAH) mechanism is presented for modeling the combustion and soot formation processes of n-dodecane and compared with the optical studies conducted in the constant volume vessel from the engine combustion network (ECN). The proposed reduced n-dodecane-PAH mechanism consists of 100 species and 432 reactions, and it is also validated with available...
Pure liquid properties, such as density, refractive index and dynamic viscosity of 2,5-dimethylfuran (DMF), a promising biofuel obtained from biomass, were determined over the temperature range (288.2–333.2)K. Liquid–liquid equilibrium (LLE) data of ternary systems water+DMF+alcohols (1-butanol or 2-butanol or 1-hexanol) were experimentally investigated at 298.2K and 313.2K at atmospheric pressure,...
Aim of the paper is the analysis of experimental data from digestate from buffalo sewage gasification carried out at high pressure, close water critical condition. Experiments were performed in a semi-continuous reactor, by loading the biomass, continuously feeding the pressurised water and removing the gas product from the reaction vessel. At a fixed value of temperature (310°C), two pressure levels...
The loaded salts (NaCl, KCl, MgCl2, and CaCl2) have significantly different influence on the contribution of dehydration and depolymerization reactions to the decomposition of sugar structures during cellulose fast pyrolysis at 325°C. The structures of salt-loaded celluloses already become cross-linked during heating-up period, largely due to the enhanced dehydration reactions catalyzed by inorganic...
This study focuses on evaluating the effect of residual lipid co-hydroprocessing with a heavy petroleum fraction, towards the production of a hybrid diesel fuel of increased sustainability. Firstly, the effect of Waste Cooking Oil (WCO) co-hydroprocessing with Heavy Atmospheric Gas Oil (HAGO) at different relative ratios (100/0, 95/5, 90/10, 85/15, 80/20 and 70/30v/v) was evaluated in terms of diesel...
