Dry reforming of methane (DRM) is a promising reaction to utilize two major greenhouse gases, namely CO2 and CH4 to produce syngas. Nickel-based catalysts would be a suitable catalyst in the industrial process of DRM reaction, because of its outstanding activity, low cost and abundant supplies. However, they are prone to coke deposition, metal oxidation, and sintering of metal particles. To overcome the limitations, mesoporous materials with well defined pores have shown interesting results to disperse the metal into the support surface. And also, coking resistance of nickel catalysts with support is diffenet among the pore size of mesoporous support. In the present study, nickel catalysts supported on mesoporous alumina having controlled pore size were synthesized by employing different micelle expander materials and the effects of pore size on coking resistance is verified by measuring BJH pore diameter and catalytic performance test. |
