“…However, the CH4 conversion is mostly influenced by the reaction temperature which is consistent with Arrhenius observation [30]. This observation is consistent with the findings of Serrano-Lotina and Daza [31] who reported the influence of reaction temperature ranged 450-850 o C on CH4 conversion. Furthermore, the three factors displayed different level of interactions as shown in Figures 13 (a)-(c).…”

In this study, the potential of dry reforming reaction over CaFe2O4 supported Ni and Co catalysts were investigated. The Co/CaFe2O4 and Ni/CaFe2O4 catalysts were synthesized using wet impregnation method by varying the metal loading from 5-15 %. The synthesized catalysts were tested in methane dry reforming reaction at atmospheric pressure and reaction temperature ranged 700-800 o C. The catalytic performance of the catalysts based on the initial screening is ranked as 5%Co/CaFe2O4 < 10%Co/CaFe2O4 < 5%Ni/CaFe2O4 < 10%Ni/CaFe2O4 according to their performance. The Ni/CaFe2O4 catalyst was selected for further investigation using full factorial design of experiment. The interaction effects of three factors namely metal loading (5-15 %), feed ratio (0.4-1.0), and reaction temperature (700-800 o C) were evaluated on the catalytic activity in terms of CH4 and CO2 conversion as well as H2 and CO yield. The interaction between the factors showed significant effects on the catalyst performance at metal loading, feed ratio and reaction temperature of 15 %, 1.0, and 800 o C. respectively. The 15 wt% Ni/CaFe2O4 was subsequently characterized by Thermogravimetric (TGA), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDX), X-ray Photoelectron Spectroscopy (XPS), N2-physisorption, Temperature Programmed Desorption (TPD)-NH3, TPD-CO2, and Fourier Transform Infra Red (FTIR) to ascertain its physiochemical properties. This study demonstrated that the CaFe2O4 supported Ni catalyst has a good potential to be used for syngas production via methane dry reforming.

“…Thermodynamic calculations [14] have shown that the conversion rate of CH4 and CO2 are greater than those expected from the dry reforming reaction alone, demonstrating the occurrence of secondary Table 3. The data shows that with the increase of CO2 flow rate, the total gas yield increased, from 52.41 wt.% with no addition of CO2 to 92.70 wt.% at a CO2 flow rate of 3.0 g h -1 and thereafter steadily increased to reach 99.40 wt.% at a CO2 flow rate of 9.0 g h -1 .…”

“…A study on dry reforming of methane over a Ni/ -Al2O3 catalyst in a fixed bed continuous flow quartz reactor and direct current corona discharge found an increase selectivity for CO and decreased carbon formation on the catalyst surface [13]. Dry methane reforming is not only affected by temperature, but also the CH4/CO2 ratio, mass to flow ratio, catalyst selection and reaction mixture [14][15][16].…”

Abstract:Catalytic dry (CO2) reforming of waste plastics was carried out in a two stage, pyrolysis-catalytic reforming fixed bed reactor to optimise the production of syngas (H2 + CO). The effects of changing the process parameters of, catalyst preparation conditions, catalyst temperature, CO2 input rate and catalyst:plastic ratio were investigated. The plastics used was a mixture of plastics simulating that found in municipal solid waste and the catalyst used was Ni-Co-Al2O3. The results showed that changing each of the process conditions investigated, all significantly influenced syngas production. An increase of 17 % of syngas production was achieved from the experiment with the catalyst prepared by rising-pH technique compared to preparation via the impregnation method. The optimum syngas production of 148.6 mmolsyngas g -1 swp was attained at the catalytic dry reforming temperature of 800 °C and catalyst:plastic ratio of 0.5. The increase of CO2 input rate promoted a higher yield of syngas.

“…Consequentially, the syngas ratio tends to increase above unity. Findings by SerranoLotina and Daza [37] shows that production of syngas ratio close to unity is favoured at feed ratio between 0.6 and 0.9. This trend is also corroborated by the work of [38] and [39] who obtained syngas ratio close to unity at feed ratio of 1.…”

Production of CO-rich hydrogen gas from methane dry reforming was investigated over CeO2-supported Co catalyst. The catalyst was synthesized by wet impregnation and subsequently characterized by field emission scanning electron microscope (FESEM), energy-dispersive X-ray spectroscopy (EDX), liquid N2 adsorption-desorption, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) for the structure, surface and thermal properties. The catalytic activity test of the Co/CeO2 was investigated between 923-1023 K under reaction conditions in a stainless steel fixed bed reactor. The composition of the products (CO and H2) from the methane dry reforming reaction was measured by gas chromatography (GC) coupled with thermal conductivity detector (TCD). The effects of feed ratios and reaction temperatures were investigated on the catalytic activity toward product selectivity, yield, and syngas ratio. Significantly, the selectivity and yield of both H2 and CO increases with feed ratio and temperature. However, the catalyst shows higher activity towards CO selectivity. The highest H2 and CO selectivity of 19.56% and 20.95% respectively were obtained at 1023 K while the highest yield of 41.98% and 38.05% were recorded for H2 and CO under the same condition.
