- ItemDevelopment of Highly Stable Low Ni Content Catalyst for Dry Reforming of CH4-Rich Feedstocks(Weinheim : WILEY-VCH Verlag, 2020) Ha, Quan Luu Manh; Lund, Henrik; Kreyenschulte, Carsten; Bartling, Stephan; Atia, Hanan; Vuong, Than Huyen; Wohlrab, Sebastian; Armbruster, UdoHighly active and coking-resistant Ni catalysts suited for the dry reforming of CH4-rich gases (70 vol %, e. g. biogas or sour natural gas) were prepared starting from a Mg-rich Mg−Al hydrotalcite support precursor. Calcination at 1000 °C yields two phases, MgO and MgAl2O4 spinel. Complexation-deposition of Ni with citric acid on the preformed support as well as lanthanum addition yields a catalyst with remarkably low carbon accumulation over 100 h on stream attributed to both high Ni dispersion and preferred interactions of Ni with MgO on MgAl2O4. © 2020 The Authors.
