Catalytic pyrolysis of Sweet Sorghum plant by using fixed-bed reactor; Effect of different temperatures on the pyrolytic bio-oil yield and FT-IR characterization

Abstract

Pyrolysis of sweet sorghum, lignocellulosic graminaceous plant has been conceded using the fixed bed tubular reactor. Temperature plus catalyst are the important factors which effect the pyrolysis process. Here catalytic pyrolysis has been done by the catalyst ZnO-Fe2O3/Al2O3 at different temperatures. We have done our pyrolysis reactions on3changed temperatures i.e. 250̊ C, 350 ̊C, 450 ̊C. By using catalyst, we obtain the pyrolytic products at a very low temperature and it is proved very efficient method for biofuel production. From different temperature experimentation, we concluded that the best optimal temperature along with catalyst for pyrolysis is 350 ̊C for the yield of bio oil. Maximum yield can be obtained at this temperature.
