| Abstract |
The purpose of the work is to upgrade pyrolytic oil from pyrolytic catalysis cracking (PCC) to reduce acidity and oxygen contents by using in-situ hydrodeoxygenation (deoxygenation) using methanol as an in situ hydrogen donor. The reaction condition of work was tested at varying temperatures of 210, 220,230 °C and time of 3,6,9,12 h. The study effect of differences from Nickel (II) nitrate (Ni (NO3)2·6H2O (97.0% purity) reduce oxidation state to get nickel (Ni0) by horizontal tube furnace at a temperature of 550 °C for 5 h under an atmospheric of 10% H2 mixed with 90% N2. loading (0, 3, 6, 9, and 12wt%) on support HZSM-5 (SiO2/Al2O3 = 40) were examined by using the incipient wetness impregnation method. The physical and chemical properties of catalysts were characterized by XRF, XRD, N2 adsorption-desorption, TGA, FESEM, EDS, FTIR, XPS, and XANES. The upgrading oil products were analyzed using density (ASTM D1480-07), viscosity (ASTM D445 D240), HHV (ASTM D2015), total acid number (TAN) (ASTM D664), CHNO, GC-MS, TGA, and FTIR. The best upgrading oil was distilled following ASTM D86 to separate bio-gasoline, bio-kerosene, and bio-diesel. The acidity, density, HHV, and viscosity were done to compare bio-fuel before and after upgrading. The results were shown that NiO/HZSM5 could be successfully reduced to Ni/HZSM5 confirmed by XRD, FTIR, XPS, and XANES. The morphology of catalysts displayed in a spherical shape and agglomerated in higher Ni loading of more than 12%. The Ni contents were effect by the hydrodeoxygenation (HDO) reaction. The optimal Ni loading was about 12% giving the lowest oxygen content in upgrading oil products. However, the reduced oxygen contents of more than 82% compared with raw material pyrolytic oil from pyrolytic catalysis cracking (PCC) condition 3 wt% K2O-MgO/CaO 525 °C.
