“…The presence of CNTs with different sizes was observed for the case of Co/ZrO 2 whereas a reactive carbon was deposited on CeO 2 after the DRM reaction, which has then oxidized due to the high oxygen storage capacity of CeO 2 . To further understand the catalytic activity of Co/CeO 2 catalyst, a similar study was conducted by Ayodele et al [40] to investigate the impact of the reactants partial pressure on the catalytic performance. It was found that reactants partial pressure of 45 kPa was optimum with about 80% CH 4 conversion and H 2 /CO ratio close to unity.…”

Abstract:Over the past few years, great attention is paid to syngas production processes from different resources especially from abundant sources, such as methane. This review of the literature is intended for syngas production from methane through the dry reforming (DRM) and the steam reforming of methane (SRM). The catalyst development for DRM and SRM represents the key factor to realize a commercial application through the utilization of more efficient catalytic systems. Due to the enormous amount of published literature in this field, the current work is mainly dedicated to the most recent achievements in the metal-oxide catalyst development for DRM and SRM in the past five years. Ni-based supported catalysts are considered the most widely used catalysts for DRM and SRM, which are commercially available; hence, this review has focused on the recent advancements achieved in Ni catalysts with special focus on the various attempts to address the catalyst deactivation challenge in both DRM and SRM applications. Furthermore, other catalytic systems, including Co-based catalysts, noble metals (Pt, Rh, Ru, and Ir), and bimetallic systems have been included in this literature review to understand the observed improvements in the catalytic activities and coke suppression property of these catalysts.

“…Zeng et al [39] investigated the CO-rich hydrogen production by methane dry reforming over Co/g-Al 2 O 3 modified with rare earth metal and reported that the catalyst was stable up to 320 h time-on-stream with H 2 selectivity of 98 %. Similarly, Co supported on CeO 2 , Sm 2 O 3 , Pr 2 O 3 La 2 O 3 , and Nd 2 O 3 used for CO-rich hydrogen production in methane dry reforming displayed good stability and activity [11][12][13][14].…”

The effect of process interaction and response surface optimization of hydrogen‐rich syngas production by catalytic carbon dioxide (CO2) reforming of methane (CH4) was evaluated. The Box‐Behnken design was applied to investigate the influence of CH4 partial pressure, CO2 partial pressure, and temperature on the hydrogen yield. The analysis of variance indicated that temperature and CH4 partial pressure had the most significant impact on the hydrogen yield. Under optimum conditions a maximum hydrogen yield of 71.38 % was achieved. Model validation with the ideal conditions confirmed close agreement of the predicted hydrogen yields with experimental values.

Catalytic reforming of Methane (CH 4 ) and carbon dioxide (CO 2 ) is one of the techniques used for the production of hydrogen and syngas. This technique has dual advantages of mitigation of greenhouse gases and production of hydrogen and syngas which are often used as intermediates for the synthesis of valuable chemical products and oxygenates. This study presented an overview of the application of response surface methodology (RSM) in the optimization of hydrogen and syngas production from catalytic reforming of CH 4 and CO 2 . The different catalytic system that has been employed together with the nature of experimental design, input parameters, responses, the optimum conditions and the maximum values of their responses were examined. The future research direction in the application of RSM to optimization of hydrogen and syngas production by catalytic reforming of CH 4 and CO 2 was recommended.
