在固定床连续流动反应器中，于200-360°C、常压下，以二甲醚水合催化剂和甲醇水蒸气重整催化剂的机械混合物为催化剂，研究了二甲醚水蒸气重整制富氢气体的催化反应。发现沉积在γ-Al 2 O3上的12-钨硅杂多酸（DME水合催化剂）和沉积在SiO2上的铜（甲醇蒸汽重整催化剂）的机械混合物提供100%DME转化率和约71 vol.%的氢气出口浓度在290°C和GHSV 1200 h −1下。
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-Al2O3(DME hydration catalyst) and copper deposited on SiO2(methanol steam reforming catalyst) provided a 100% DME conversion and hydrogen outlet concentration of ∼71vol.% at 290°C and GHSV ∼1200h−1.
