Abstract: Summary The improvement of hydrogen concentration in the obtained syngas during methane dry reforming is strongly demanded. Additionally, enhancement of CO2 and CH4 conversions has been of high preference. In line with these aims, this research work studies the impact of incorporating lanthanum metal either as a catalytic promoter or as a cosupport, on the efficiency of the reforming process. Two percentages namely 2.5 and 5 wt% were added to a catalyst composed of Ni(10%)–Zr(90%). Thus, four catalytic composi… Show more

“…04‐006‐8247 are characteristic for MgO, Periclase. The absence of characteristic peaks of NiO indicated the high dispersion of Ni nanoparticles onto the support surface and confirmed that the produced NiO crystals are less than 3 nm 1.…”

“…The test apparatus and the catalytic reforming procedure are the same as those reported in El-Salamony et al [1]. The reaction mixture of CO 2 /CH 4 /Ar in proportions of 1:1:4, 1:1.5:4, and 1:2:4 regulated by mass flow controllers was adjusted to give flow rates corresponding to GHSV values, i.e., 2000, 4000, 6000 ccg -1 h -1 , respectively.…”

“…Moreover, the NiO crystalline size was calculated using Scherrer's formula; the crystal sizes were arranged in the following order: Ni-Imp (21.36 nm) 4 Ni-La-Imp (20.93 nm), which indicated that La-doping did not cause a significant change in the crystal size of NiO particles, which was consistent with the literature reports. 26,27 The particle size of the Ni-La-Sol catalyst was smaller, as the characteristic peaks of the Ni-La-Sol catalyst was much broader and of lower intensity, compared with those of the Ni-La-Imp catalyst. The characteristic peaks of the Ni-La-Imp-P and Ni-La-Sol-P catalysts were much broader and of lower intensity, compared with those of Ni-La-Imp and Ni-La-Sol, which revealed that the particle size was smaller.…”
