TL;DR: In this article, a fixed-bed continuous-flow reactor at a temperature of 200-360°C under atmospheric pressure over a mechanical mixture of catalysts for DME hydration and for methanol steam reforming was studied.
Abstract: Catalytic reaction of steam reforming of dimethyl ether (DME) to hydrogen-rich gas was studied in a fixed-bed continuous-flow reactor at a temperature of 200–360°C under atmospheric pressure over a mechanical mixture of catalysts for DME hydration and for methanol steam reforming. It was found that the mechanical mixture of 12-tungstosilicoheteropolyacid deposited on γ-Al 2 O 3 (DME hydration catalyst) and copper deposited on SiO 2 (methanol steam reforming catalyst) provided a 100% DME conversion and hydrogen outlet concentration of ∼71 vol.% at 290°C and GHSV ∼1200 h −1 .

TL;DR: In this paper, a two-layer fixed-bed catalytic reactor for syngas production by steam reforming of ethanol has been proposed, where ethanol is first converted to a mixture of methane, carbon oxides and hydrogen over a Pd-based catalyst.
Abstract: A two-layer fixed-bed catalytic reactor for syngas production by steam reforming of ethanol has been proposed. In the reactor, ethanol is first converted to a mixture of methane, carbon oxides and hydrogen over a Pd-based catalyst and then this mixture is converted to syngas over a Ni-based catalyst for methane steam reforming. It has been shown that the use of the two-layer fixed-bed reactor prevents coke formation and provides the syngas yield closed to equilibrium.
