Ni catalysts were prepared by wet impregnation of three different supports: alumina, niobia and 10 wt.% niobia/alumina, prepared by (co)precipitation. The catalysts were evaluated on steam reforming of glycerol at 500 °C, for 30 h. The catalyst supported on Nb₂O₅/Al₂O₃ presented the best performance, with higher conversion into gas (80%) during all reaction time and hydrogen yield of 50%. Alumina supported catalyst showed higher deactivation and lower hydrogen yield. All catalysts showed coke formation, but it was formed in larger amount on the catalysts supported on single oxides. A depth study was conducted to evaluate the effect of reaction variables as space velocity, glycerol concentration in feed and temperature on the catalytic performance of the Nb₂O₅/Al₂O₃ catalyst. Kinetic study was also performed for this catalyst using two different approaches, obtaining glycerol and steam orders, as well as the apparent activation energy.

Ni催化剂是通过湿法浸渍三种不同的载体制备的：氧化铝，氧化铌和10％（重量）的氧化铌/氧化铝，是通过（共）沉淀法制备的。在500°C的甘油蒸汽重整30小时的条件下对催化剂进行了评估。负载在Nb ₂ O ₅ / Al ₂ O ₃上的催化剂表现出最好的性能，在所有反应时间内转化成气体的比例更高（80％），氢气产率为50％。氧化铝负载的催化剂表现出更高的失活和更低的氢产率。所有催化剂均显示出焦炭形成，但是在负载于单一氧化物上的催化剂上形成了大量焦炭。进行了深入研究，以评估反应变量（如空速，进料中的甘油浓度和温度）对Nb ₂ O ₅ / Al ₂ O ₃催化剂的催化性能的影响。还使用两种不同的方法对该催化剂进行了动力学研究，获得了甘油和蒸汽量，以及表观活化能。
