Mesoporous Ni/γ- Al₂O₃ catalysts with various Ni contents were synthesized and employed in glycerol dry (CO₂) reforming (GDR) reaction. The results revealed that increasing the Ni content from 5 to 20 wt.%, decreased the BET areas of the samples from 180 to 143 m²/g and increased the Ni crystalline size from 6.6 to 19 nm. Moreover, the catalytic activities of different catalysts were studied and the results revealed that 15 wt.% Ni/Al₂O₃ possessed the maximum catalytic activity. Finally, the stability of the catalyst with maximum activity was investigated for 20 h of reaction at 700 °C. The results showed a significant decline in catalytic activity during the first 5 h of reaction followed with a stable activity for 15 h time on stream.

中孔镍/γ-铝_2种ö ₃催化剂与各种Ni含量被合成并在甘油干燥（CO采用₂）重整（GDR）反应。结果表明，将Ni含量从5wt。％增加到20wt。％，将样品的BET面积从180m ³ / g减少到143m ² / g，并且将Ni晶体尺寸从6.6nm增加到19nm。此外，研究了不同催化剂的催化活性，结果表明Ni / Al ₂ O _3为15 wt％。具有最大的催化活性。最后，在700°C下反应20小时，研究了具有最大活性的催化剂的稳定性。结果显示，在反应的前5小时内，催化活性显着下降，随后在运行15小时内，其催化活性却保持稳定。
