CH4 and CO2 are greenhouse gases. Hence, their emission to the atmosphere must be controlled to avoid the global warming. Dry reforming of methane could provide a valuable tool in alleviating this problem as well as producing synthesis gas. This process is hampered by rapid catalyst deactivation due to carbon deposition and sintering of both the support and active metal. The presented study focuses on the experimental investigation the effect of addition of Calcium promoter to 1%Ni catalysts supported on a mixed 80%α-Al2O3 and 20%TiO2-P25 support. The performance of the developed catalyst was quantified by determining CH4 and CO2 conversions, synthesis gas ratio (H2/CO) and stability. Spent and fresh catalysts were characterized by TGA, SEM and EDS. Time on stream stability tests of the promoted catalyst showed that addition of limited amounts of Ca promoter would reduce carbon formation.
