摘要：

A nickel catalyst on mesoporoussilica created through a direct synthesis and modified with a strontium promoter. After conducting dry and steam reforming tests, the prepared samples characterized using the XRD, XRF, BET, TPR and HR-TEM, and then considered to study the catalyst stability and activity. And, the CH 4 and CO 2 conversion and ratio of H 2 /CO with using the Sr - Ni/MCM-41 catalyst in the DRM and SRM processes at 700 degrees C, were determined about (73.3% and 80.6%), (55.81% and 60.25%), and (0.88 and 3.1), respectively. Furthermore, SEM, TPR, and TPD analysis were used to characterize the utilized catalyst. The finding demonstrated a good structural order and the specific surface area (SSA) of 889.5 m 2 /g. The presence of a strontium enhanced nickel oxide ' s reducibility and strengthened its interaction with the base. Furthermore, strontium enhanced the catalytic activity.
