The influence of iron oxide on the oxidation kinetics of synthetic char derived from thermogravimetric analysis and fixed-bed experiments under isothermal and temperature-programmed conditions
Autor: Hendrik Düdder, Katrin Lotz, Martin Muhler, Annika Wütscher
Publikováno v: Fuel. 201:99-104
The catalytic effect of iron oxide on the oxidation kinetics of synthetic char was investigated in a fixed-bed reactor and in a conventional thermobalance for comparison. Synthetic char doped with iron oxide was obtained by pyrolyzing hydrochar at 80

Synthesis and characterization of lignite-like fuels obtained by hydrothermal carbonization of cellulose
Autor: Hendrik Düdder, Raphael Stoll, Annika Wütscher, Martin Muhler
Publikováno v: Fuel. 171:54-58
Hydrothermal carbonization of cellulose was used to synthesize a mineral-free lignite-like solid fuel. By varying the reaction time the elemental composition was tuned to fit the composition of real lignite. Minerals were removed from real lignite by

Publikováno v: Catalysis Today
The influence of redox dynamics of a Ni/MgAl oxide catalyst for dry reforming of methane (DRM) at high temperature was studied to correlate structural stability with catalytic activity and coking propensity. Structural aging of the catalyst was simul
