Abstract

The catalytic performance evaluation of Ni - based catalysts on SiO₂, Al₂O₃, TiO₂-SiO₂, TiO₂-Al₂O₃ supports for CO₂-reforming of methane to syngas was investigated in temperature range from 873 to 1073K using feed stock with a CH₄/CO₂ ratio of 1. CH₄ and CO₂ coversions as well as CO and H₂ selectivities increased with increasing reaction temperature and decreased with increasing GHSV. TiO₂ promoter, which was used to modified catalysts through adsorption of TiCl₄ gas method, effectively improved catalytic activities. The improving effects of TiO₂ on the catalytic activities are probably due to the contributions to improving the SMSI effects of the catalysts.
