Özet
Slow pyrolysis of hornbeam (Carpinus betulus L.) sawdust was performed to produce bio-oil and bio-char. The operational variables were as follows: pyrolysis temperature (400-600 degrees C), heating rate (10-50 degrees C min(-1)) and nitrogen flow rate (50-150 cm(3) min(-1)). Physicochemical and thermogravimetric characterizations of hornbeam sawdust were performed. The characteristics of bio-oil and bio-char were analyzed on the basis of various spectroscopic and chromatographic techniques such as FTIR, GC-MS, 1H NMR, SEM, BET. Higher heating value, density and kinematic viscosity of the bio-oil with maximum yield of 35.28% were 23.22 MJ kg(-1), 1289 kg m(-3) and 0.6 mm(2) s(-1), respectively. The bio-oil with relatively high fuel potential can be obtained from the pyrolysis of the hornbeam sawdust and the bio-char with a calorific value of 32.88 MJ kg(-1) is a promising candidate for solid fuel applications that also contributes to the preservation of the environment.
