Accessible Surface

Hierarchical Ni/Al2O3 nanocomposite possesses a high surface area, high loading of well dispersed metal nanoparticles, and a hierarchical hollow structure. The strong interaction between metal and support and the large open accessible surface lead to excellent sintering and carbon resistance, and superior catalytic performance in methane dry reforming.

Co2 Reforming Of Ch4

Ni, Co, and Co–Ni bimetallic catalysts supported over SBA-15 and over SBA-15 doped with Zn or Ce oxides were prepared and tested in a methane dry reforming reaction. The loading of the metals in the catalyst was 5 wt % for either mono or bimetallic catalysts. The prepared catalysts were tested in a continuous-flow fixed-bed reactor at 800 °C under atmospheric pressure. XRD, TPR, TPD, and SEM characterization techniques were employed to investigate the catalytic properties of fresh catalysts. SEM and TGA were used to study the catalytic properties of spent catalysts. A remarkable effect on the reduction properties and catalytic performance of catalysts was observed after adding Zn and Ce. Over an 8 h test, Ni/SBA-15 showed the best activity and stability. The conversion was 90% for CH4 and CO2. Co–Ni/SBA-15 and Co–Ni/Ce–SBA-15 have shown a reasonable activity and stability. Selectivity of the Ni/SBA-15 catalyst was higher than all other catalysts as indicated by the H2/CO ratio. Co/SBA-15 and Co–Ni/Zn–SBA-15 showed a low activity and selectivity. TPD–NH3 profiles indicated that doping SBA-15 with Ce and/or Zn increased the catalyst acidic sites. Ni/SBA-15 is an excellent potential catalyst for commercial methane dry reforming processes.

Synthetic gas - a combination of (H2) and (CO) - is an important chemical intermediate for the production of liquid hydrocarbon, olefin, gasoline, and other valuable chemicals. Several reforming methods that use steam, carbon dioxide, and oxygen in the presence of various catalytic systems have been extensively investigated, and this paper reviews the recent research on the state-of-the-art of reforming technologies and the effect of parameters on the catalytic activity of mesoporous silica/alumina supported nickel catalysts for syngas production by methane dry reforming. First, we provide an overview of reforming technologies, including methane dry reforming, steam methane reforming, partial oxidation of CH4, and auto thermal reforming of CH4. Then, we review the literature on dry reforming catalysts. Next, we describe recent findings on the effect of parameters on the catalytic activity of mesoporous silica/alumina supported nickel catalysts for syngas production. Finally, we make proposals for future research. This study can help achieve a better understanding of the reforming technologies and the effects of parameters on catalytic performance for syngas production, thus contributing to the development of green technologies.
