چکیده انگلیسی
In this study, low cost waste chicken fat (WCF) feedstock was used for fuel-like hydrocarbon production. The effects of varying reaction parameters on the hydrocracking of waste chicken fat using NiW/SiO2-Al2O3 catalyst were investigated. The reactions were carried out in a fixed bed down flow reactor at reaction temperatures of 400-450 °C, liquid hourly space velocity (LHSV) of 1, 2, 4 hâ1, H2/oil molar ratio of 450 v/v and hydrogen pressures of 6.0 MPa. The effects on hydrocracking conversion and distribution of products were investigated. The liquid product was analyzed using gas chromatography (GC) to quantify n-alkanes. Hydrocracking conversion and organic liquid products (OLPs) were evaluated by ASTM D-2887 distillation. The results showed that the catalytic hydrocracking of WCF generates fuels that have chemical and physical properties comparable to those specified for petroleum-based fuels. The amount of kerosene/diesel fractional product decreased with an increase in the temperature and a decrease in the LHSV; while gasoline like petroleum fuel increased. A considerable elimination of O2 from chicken waste fat molecules has been indicated by FTIR analysis. The oxygen removal pathway of WCF over NiW/SiO2-Al2O3 catalyst is primarily carried out by hydro-deoxygenation. The reaction was found to follow the second order mechanism, and the estimated activation energy Ea was 96 kJ molâ1. The exploited catalyst was employed in another run where the results showed the catalyst stability and can be used for several times.
