摘要：
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 degrees C, atmospheric pressure and gas hourly space velocity of 12000 mL/g(car) . 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. (c) 2013 Elsevier B.V. All rights reserved.
