摘要：

The activity of monometallic (Ni/gamma-Al2O3, Co/gamma-Al2O3) and bimetallic (Ni-Co/gamma-Al2O3) catalysts deposited on 'y-aluminium oxide was studied for the dry reforming of methane into synthesis gas. It was determined that the bimetallic catalyst is more active than the monometallic one. It was established with the help of a set of methods (X-ray phase analysis and temperature-programmed reduction with hydrogen) that the surface bimetallic Ni Co alloy is formed in the presence of the bimetallic catalyst Ni-Co/gamma-Al2O3. This alloy plays an essential part in the suppression of the formation of carbonaceous deposits on the catalyst surface and in the enhancement of the catalyst activity.
