Significantly, a 72 h longevity study was carried out at 1023 K over the 3 wt% La catalyst and the trend is depicted in Fig. 11. The 3 wt% La catalyst has yielded stable performance with no apparent severe deactivation. The exit flow rate was averaging 190 ml min−1. In addition, Fig. 12 reveals that Hygromycin B the transient glycerol conversion, Xg (averaging 90.0%) as well as the product compositions for H2 (30.0 mol%), CO (20.0 mol%) and CH4 (1–2.0 mol%) were stable over the entire 72 h. Therefore, it can be concluded that the 3 wt% La–Ni/Al2O3 catalyst was able to catalyze glycerol dry reforming over an extended period of reaction without significant deactivation.
