Abstract

Nickel-magnesia solid solution catalyst with low Ni content had excellent stability for CO₂ reforming of methane and steam reforming under low steam to methane ratio at 1123 K without deposited carbon. The deactivation due to oxidation of active nickel species observed under some reaction condition. Nickel-magnesia solid solution and magnesia supported nickel catalysts were characterized by means of FTIR, temperature programmed reaction of CO₂. It was found that small nickel particles formed on Ni _0.03Mg_0.97O solid solution catalyst have high ability to reduce CO ₂. Though this ability causes the deactivation due to oxidation, this also plays an important role in inhibiting carbon deposition.
