Preparation of an Industrial Ni-Based Catalyst and Investigation on CH4/CO2 Reforming to Syngas

An industrial cylinder Ni-based catalyst, LaNiO x /ZSM-5 (ϕ = 3 mm), was prepared by a sol−gel method, and its catalytic performance was investigated for CH 4 /CO 2 reforming reaction not only in laboratory scale but also in pilot plant scale. The result revealed that the conversion of CH 4 and CO 2 was 97% and 94%, respectively, at 850 °C and gas hour space velocity = 1.3 × 10 3 h −1 and remained a constant in the 100 h range, whereas carbon yield was ca. 5%. The properties of the catalyst were characterized by means of techniques such as X-ray diffraction (XRD), Brunauer−Emmett−Teller (BET) surface area, high-resolution transmission electron microscopy (HRTEM), temperature-programmed reduction (TPR), and temperature-programmed oxidation (TPO) and compared to those of La 2 NiO 4 /MCM-41 and La 2 NiO 4 /γ-Al 2 O 3 catalysts.
