Upgrading Of Fast Pyrolysis Oil Via Hdo Using Nano-Structured Catalysts, Shima Ahmadi
Electronic Thesis and Dissertation Repository
The effects of type of solvents (hydro-treated or upgraded pyrolysis oil and ethanol) on hydro-de-oxygenation (HDO) of fast pyrolysis oil were studied. The presence and the type of solvent were found to be effective for prevention or reduction of self-polymerization during the bio-oil HDO process. Using ethanol as the solvent had superior performance in terms of the heating value, molecular weight and elemental composition of the upgraded oil products, compared to using hydro-treated oils as the solvent. Furthermore, novel CoMo catalysts supported on nano-structured materials including MCM-41 and SBA-15 were synthesized and tested on HDO of fast pyrolysis oil in …
