| Abstract: | A Co/Zr/SiO2 catalyst for Fischer-Tropsch synthesis was prepared under an ultrasound environment. The influence of different ultrasonic powers on catalyst performance was studied. The catalysts were characterized by N2 physisorption,X-ray diffraction,H2 tempera-ture-programmed desorption,H2 temperature-programmed reduction,and transmission electron microscopy. The results show that ultrasound assisted in increasing the BET surface area of the catalysts and the even the dispersion of small cobalt crystallite... |
