Single stage upgrading with the help of bifunctional catalysis of Pt supported on solid acid for converting product oil of triglyceride thermal cracking into drop-in fuel

Although thermal cracking of triglyceride is one of the potential technologies to produce drop-in fuel from biomass resources, product oil of the triglyceride thermal cracking consists of straight-chain hydrocarbons and fatty acids which degrade fuel properties. In order to convert the product oil into drop-in fuel, single stage upgrading catalyzed by Pt supported on solid acid was studied on the basis of experimental data from autoclave test reaction. Primarily, catalytic isomerization of tetradecane was carried out for investigating an upper limitation of the reaction temperature. Also, Y zeolite, mordenite and AISBA-15 were used as the supporting material in order to examine effects of their acidity on catalysis for the tetradecane isomerization. Then, catalytic hydroisomerization of 1-tetradecene was verified at the limited temperatures and under. Finally, a mixture of 1-tetradecene and oleic acid as a model product oil of the triglyceride thermal cracking was employed for the autoclave test reaction. To the best of our knowledge, the present work is the first successful result for catalyzing simultaneously all the reactions required for the post-upgrading of the triglyceride thermal cracking process.
