Ni based on dual-support Mg-Al mixed oxides and SBA-15 catalysts for dry reforming of methane

A series of new dual support Ni catalysts consisting of Mg-Al mixed oxides and SBA-15 was prepared. The performance of the catalysts in the dry reforming of methane to syngas was investigated at 800 °C, atmospheric pressure and gas hourly space velocity of 12000 mL/gcat · h. The ordered hexagonal mesoporous structure of SBA-15 coated with Mg-Al mixed oxides was found to be maintained. One of the composite catalysts exhibited excellent anti-deposition of carbon and high stability for 500 h on stream. It is concluded that strong metal-support interaction promoted catalyst performance by inhibiting carbon deposition and metal sintering.
