Ni-Fe catalyst derived from mixed oxides Fe/Mg-bearing metallurgical waste for hydrogen production by steam reforming of biodiesel by-product: Investigation of catalyst synthesis parameters and temperature dependency of the reaction network

Solventless hydrodeoxygenation of isoeugenol and dihydroeugenol in batch and continuous modes over a zeolite-supported FeNi catalyst

“…S10b †). This is in line with lamentous type coke formation (400-550 °C) observed also over Ni-upgraded slug oxides, 29 and FeNi/H-Y-5.1. 12 Sánchez-Sánchez et al 30 reported that the oxidation of lamentous coke coupled with Ni particles occurs in the temperature range between 300 and 530 °C, while the oxidation of carbonaceous deposits with various degrees of graphitization occurs above 530 °C.…”

Dry Reforming of Methane over Rare-Earth Metal Oxide Ni–M–Al (M = Ce, La) Catalysts

“…The same order was observed by CHNS analysis, as described above. The maximum of heat release observed at 575 °C pointed out on the filamentous type of coke formation observed also over nickel catalysts supported on mixed oxides Fe/Mg-bearing metallurgical waste and FeNi/H–Y-5.1 . Furthermore, TGA of the fresh catalysts in the presence of air revealed phase transformations for 15Ni–15Ce–20Al (5.3 wt %) > 15Ni–15La–20Al (3.2 wt %).…”

Glycerol and Catalysis by Waste/Low-Cost Materials—A Review

“…The catalytic performance of Ni-UGS was superior to a commercial alumina-based steam reforming catalyst with higher Ni content (29.8% by weight): 86% conversion of Gly gas with 71% H 2 yield. Better results were obtained in a second work by the same group [47], making a comparative study of Ni-UGSO catalysts prepared by ultrasound-assisted SSI and WI methods with Ni loading (5%), providing almost complete conversion of Gly into gaseous products with high H 2 yield (80.7%). According to the authors, the good performance of the SSI-5%Ni-UGSO catalyst, and the synergistic effect observed between Ni and Fe/Mg by the formation of active sites Ni-Fe 2 O 4 and Ni-MgO through the method of state synthesis, benefited both Gly conversion and H 2 selectivity.…”
