In this work, the effect of ZrO2 particle size on the surficial and structural properties and catalytic performance of Mo-based catalysts towards sulfur-resistant methanation was investigated. The results showed that the catalytic activity correlated closely with the particle size of ZrO2. The supports and catalysts were characterized by N2-adsorption, XRD, Raman, H2-TPR and TEM to obtain the information...
Silica-supported MoO3 catalyst prepared by slurry impregnation method exhibits higher activity and dispersion capacity compared to the MoO3/SiO2 prepared conventionally. Slurry MoO3/water is used instead of the solution ammonium heptamolybdate. Highly dispersed amorphous Mo catalysts are obtained, which is closely related the catalytic activities, without calcination, waste solutions, and calcining...
