“…Ethanol is an attractive source of hydrogen, due to its non-toxic and capable of being stored, transported and handled safely [55][56][57][58][59]. There are two main processes for the production of H 2 from ethanol, which are steam reforming and thermal reforming [60,61].…”

Hydrogen is considered to be an ideal energy carrier to achieve low-carbon economy and sustainable energy supply. Production of hydrogen by catalytic reforming of organic compounds is one of the most important commercial processes. With the rapid development of photocatalysis in recent years, the applications of photocatalysis have been extended to the area of reforming hydrogen evolution. This research area has attracted extensive attention and exhibited potential for wide application in practice. Photocatalytic reforming for hydrogen evolution is a sustainable process to convert the solar energy stored in hydrogen into chemical energy. This review comprehensively summarized the reported works in relevant areas, categorized by the reforming precursor (organic compound) such as methanol, ethanol and biomass. Mechanisms and characteristics for each category were deeply discussed. In addition, recommendations for future work were suggested.

“…Under these premises, this work showcases the application of a Ni/Al 2 O 3 catalyst in the steam reforming of toluene (C 7 H 8 ) as a tar model compound in a fixed bed reactor. Until now, the catalytic performance in the steam reforming of toluene has been mainly evaluated as a function of catalyst design variables, such as the nature of the support [20][21][22] and metal [23,24], but little attention has been paid to the reaction conditions, especially for this benchmark catalytic formulation [25]. Identification and optimisation of the reaction parameters in the presence of a commercial-like catalyst (Ni/Al 2 O 3 ) are vital to achieving the best catalytic performance.…”

Identifying the suitable reaction conditions is key to achieve high performance and economic efficiency in any catalytic process. In this study, the catalytic performance of a Ni/Al2O3 catalyst, a benchmark system—was investigated in steam reforming of toluene as a biomass gasification tar model compound to explore the effect of reforming temperature, steam to carbon (S/C) ratio and residence time on toluene conversion and gas products. An S/C molar ratio range from one to three and temperature range from 700 to 900 °C was selected according to thermodynamic equilibrium calculations, and gas hourly space velocity (GHSV) was varied from 30,600 to 122,400 h−1 based on previous work. The results suggest that 800 °C, GHSV 61,200 h−1 and S/C ratio 3 provide favourable operating conditions for steam reforming of toluene in order to get high toluene conversion and hydrogen productivity, achieving a toluene to gas conversion of 94% and H2 production of 13 mol/mol toluene.

“…The best results of CoSep could be explained considering its physiochemical properties such as the smaller metallic cobalt particles and highly dispersing by favoring stronger interactions between cobalt and sepiolitic support. In literature similar results on steam reforming of different biomass derived substrates (ethanol, glycerol, acetic acid as model for biooil) over Ni and Co catalysts are described, being the smaller size of their metallic particles and their higher dispersion the main responsible of the improved catalytic performance [46,[60][61][62][63][64][65].…”

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.
