摘要：A series of MAl_2O_4(M=Ni~(2+) and Mg~(2+)) catalysts with high catalyst activity was prepared via co-precipitation. Higher sintering temperature is favorable to catalyst activity. As-prepared MAl_2O_4 catalysts were characterized by X-ray diffraction, scanning electronic microscopy, and Brunauer–Emmett–Teller method. MAl_2O_4 catalysts were evaluated using the heating values of bio-oils derived from the catalytic pyrolysis of microalgae. The heating value of the bio-oils is enhanced along with the increased sintering temperature of MAl_2O_4 catalysts. The highest heating value using MAl_2O_4 catalysts sintered at 700 ℃ was 36.298 MJ/kg, which was higher than the value when using ZSM-5.
