“…The main reduction peak located at about 430 °C is the reduction peak of free NiO. 28 The highest peak and largest reduction area indicate that the catalyst contains a large amount of NiO. There is also a reduction shoulder, and the peak temperature is about 630 °C, which may be due to the interaction between NiO and CeO 2 -ZnO support.…”

The steam reforming of bio-oil-derived acetic acid over the developed Ni/CeO 2 -ZnO nanoparticle catalysts for hydrogen production was studied. The correlations of CeO 2 to ZnO mass ratio (CZMR) and nickel loading with the properties and performances of Ni/CeO 2 -ZnO catalysts were explored. The H 2 , CO, and potential H 2 yields followed a Gaussian normal distribution with increasing the CZMR. An exponential function equation was established to correlate the H 2 , CO, and potential H 2 yields with Ni loading. As the CZMR increased from 0 to 1/3, the H 2 yield increased from 57.8 to 69.4%, with a growth rate of 20.1%. Further, on increasing the CZMR from 1/3 to 3, the H 2 yield decreased by 37.6%. The CO yield showed a similar trend for the H 2 yield on increasing the CZMR, which first increased to a peak value, then started to decrease rapidly and finally stabilized. The yield of H 2 increased significantly from 20.6 to 73.5%, with the increase of nickel loading from 0 to 15%. Further, on increasing the nickel loading from 15 to 25%, the H 2 yield increased by only 5.8%. With the CZMR of 1/3 and the nickel loading of 15%, the selectivities of H 2 and CO were as high as 91.6 and 42.3%, respectively.

“…This might be due to a very low boiling point and high vapour pressure. Recently, the study was performed by Elias et al [67] investigated the Ni/ZnO/CeO 2 -based catalysts for the steam reforming of acetone for the production of hydrogen. The study revealed that Ni/ZnO with in cooperation of CeO 2 performed better than barely Ni/ZnO.…”

The catalytic steam reforming of oxygenated hydrocarbons has been holding an interest in scientific societies for the past two decades. The hydrogen production from steam reforming of glycerol, ethanol and other oxygenates such as ethylene glycol and propylene glycol are more suitable choice not just because it can be produced from renewable sources, but it also helps to decrease the transportation fuel price and making it more competitive. In addition, hydrogen itself is a green fuel for the transportation sector. The studies on the production of hydrogen from various reforming technologies revealed a remarkable impact on the environmental and socio-economic issues. Researchers became more focused on glycerol steam reforming (GSR), ethanol steam reforming (ESR) and other oxygenates to investigate the catalyst suitability, their kinetics and challenges for the sustainability of the oil and gas production. In the present work, the authors critically addressed the challenges and strategies for hydrogen production via GSR, ESR and other oxygenates reforming process. This review covers extensively thermodynamic parametric analysis, catalysts developments, kinetics and advancement in the operational process for glycerol, ethanol and few other oxygenates. This detailed investigation only highlights the steam reforming process (SRP) of these oxygenates at the laboratory experimental stage. It was found that from this review, there are many technical issues, which lead to economic challenges. The issues are yet to be addressed and thus, these particular applications require faster accelerations at the pilot scale, taking into the consideration of the current pandemic and economic issues, for a safer and greener environment.

“…Depending on the method chosen, high dispersions of the metal phase and support metal interactions can be favored [14]. In addition, acidic support seem to promote the formation of coke precursors (ethylene), which can affect the stability of the catalyst during the steam reforming reaction [39][40][41][42][43][44][45][46][47][48]. In this work, we show by the first time the use of Co-based catalysts supported on natural sepiolite in the production of hydrogen via furfural steam reforming.…”

Natural sepiolite is a mineral very abundant in Spain, being the main producer worldwide. This material is presented by the first time as promised support to prepare cobalt catalysts with high activity and hydrogen selectivity in the steam reforming of furfural (SRF). Two methods for cobalt incorporation on natural sepiolite, precipitation (PP) and incipient wetness impregnation (IWI), are explored and their influence in the preparation of catalysts highly active and selective in the SRF is studied. PP method makes possible to synthesize a catalytic material with high catalytic performance (high conversion of furfural, > 95%, and high hydrogen selectivity, 70%). Furthermore the production of non-desired byproducts such as CO, CH4 and acetone, decrease significantly in the catalyst prepared by PP (CoSep). Characterization by N2 adsorption-desorption to determine surface area, XRD, TPR and TEM shows that PP method favors the formation of smaller metallic particles of Co with a high dispersion. These differential physicochemical properties seem to explain the better catalytic performance exhibited by the sepiolitic catalyst prepared by the PP method (CoSep). In addition, this catalyst exhibits also a higher resistance to deactivation after 24 hours of reaction time. This fact seems to be related to the lower coke deposition on the catalyst prepared by precipitation and particularly, with the lower sinterization of the metallic Co particles during the steam reforming of furfural.
