“…This study has been preceded by others from the same research group . These papers describe methods for preparing the 2 catalysts in series, as reported by González et al Their results on Fischer‐Tropsch (FT) diesel and low‐sulfur diesel ATR essentially corroborate previous and parallel knowledge of the following facts : (a) Ph, Pt and Ph‐Pt have high ATR catalytic activity; (b) Pt has higher C deposition tendency than Pd and, if not promoted, they deactivate rapidly via coke formation and sintering phenomena; (c) CeO 2 and La 2 O 3 doping is highly beneficial because of the higher O‐transfer capacity conferred; (d) Rh oxides can be correlated to catalyst activity in terms of fuel conversion. Moreover, they prove that zone‐coated catalysts, made by 2 successive (in‐series) layers wash‐coated on a monolith, where each layer is different, can offer significant advantages because the first one can be more active on POX, which is faster than SR reaction, and the second beneath the first can be more active on SR.…”

“…Very recently, González et al tested the ATR of FT diesel over bimetallic Pt‐Pd on δ‐Al 2 O 3 and CeO 2 /ZrO 2 monolithic supports. A full‐scale reformer (internal diameter = 84 mm, length = 400 mm) at 650‐750°C was included, with the 2 catalysts coated on the monoliths and positioned in series (Figure ). The catalysts were composed of 1:1 wt% Rh:Pt as active metals.…”

Although natural gas is the main feedstock for the production of hydrogen and syngas, liquid hydrocarbons and oxygenated compounds are of interest for reasons associated with their local availability and their easiness to be stored and transported. This review focuses on steam, dry, and partial oxidation of liquid feedstock. The vast research work published in these fields does not allow for a full coverage of the entire literature. Instead, the authors present from both scientific and technical stand points the knowledge which seems more promising toward eventual improvements of commercial units and utilization of new catalytic formulations. Since traditional steam reforming is relatively very well covered by other reviews, this review has mainly focused on the relatively recent works on glycerol, a biodiesel production by-product, and the widely available and distributed commercial diesel/biodiesel. New promising catalytic formulations are proposed and are actually under testing for eventual commercial use. Nevertheless these catalysts might be eventually efficient for gaseous (e.g., CH 4 ) hydrocarbons conversion to syngas. Dry and partial oxidation has also been reviewed both globally and in an incremental way. All liquid feedstock tested are reported. Finally, this review tries to bridge the gap between fundamental and factual research in this field. Both are important but the interpretation of the results remains a strong function of each paper's main focus. This review does not pretend that this gap is fully bridged but it has the ambition to help the researchers as well as the practitioners in this area to synthesize the existing knowledge.

“…The same behaviour of area decrease as the percentage of cerium increase is reported in the specific areas of monometallic and bimetallic. However, the surface areas between Ru‐ZrO 2 and Ru−Au‐ZrO 2 reveal an increase in the specific surface area 65 and 66 m 2 /g, attributed to the unification of metals on the surface of ZrO 2 and incorporation of Ru and Au within the pore channels, which influence the formation of new pore tunnels, because of this, there are areas of slightly larger surface than pure ZrO 2 , this phenomenon has been described by several researchers group . On the other hand, the results (Table ) show that the addition of cerium acetyl acetonate during supports synthesis has an effect on reaction rates of hydrolysis‐condensation during the sol‐gel method producing in this case an effect that does not benefit the surface of the specific area.…”

Catalytic Wet Air Oxidation (CWAO) of Phenol in a Fixed Bed Reactor Using Supported Ru and Ru‐Au Catalysts: Effect of Gold and Ce Loading

et al. 2019

Catalysts of Ru and Ru−Au prepared by the wet impregnation and Deposition‐Precipitation methods supported on ZrO2 modified by CeO2(10 and 20 wt%) synthetized by sol‐gel method, in order to study Au and CeO2 addition effect in the catalytic wet air oxidation of phenol, carried out in an automatized continuous fixed‐bed reactor using oxygen as an oxidizing source. Characterizations of the catalysts were made by X‐ray Diffraction (XRD), Specific Surface Area (BET), X‐ray Photoelectron Spectroscopy (XPS), Transmission Electronic Microscopy (TEM), Scanning Electronic Microscopy (SEM), Ultraviolet–visible Spectroscopy (UV‐vis) and Temperature Programmed Desorption of Ammonia (NH3‐TPD). The effect of Au is reflected in the selectivity to CO2 of the catalysts Ru‐ZrO2 and Ru−Au‐ZrO2 with the increase in selectivity from 89 to 95% related to the increase in acidity which increases from 70 to 102 (μmol of NH3/ gCat). Ce loading effect in this case was important to the enhance the CO2 selectivity explained by the formation of Ce4+‐O2−‐M that could favor the oxygen transfer between the catalyst surface and the adsorbed species by a redox mechanism.
