| Abstract: | A CuZr slurry catalyst promoted by La and Mn additives was prepared by complete liquid-phase technology. The performance of the catalyst for direct synthesis of dimethyl ether from syngas was evaluated in a slurry reactor. The catalyst was characterized by NH3 temperature-programmed desorption,powder X-ray diffraction,N2 adsorption-desorption,X-ray photoelectron spectroscopy,and H2 tempera-ture-programmed reduction. The results indicated that the addition of La and Mn promoters to the CuZr slurry catalyst e... |
