Catalysts and Catalytic Processes for the Production of Hydrogen-Rich Gas for Fuel Cell Feeding

Abstract

The paper considers new approaches to the preparation of structured catalysts and peculiarities of the processes for the production of hydrogen-rich gas from hydrocarbons and dimethyl ether for fuel cell feeding applications. The results of the studies of structured catalyst for CO removal from reformate by selective methanation are presented.

Improving the Catalytic Performance of Cobalt for CO Preferential Oxidation by Stabilizing the Active Phase through Vanadium Promotion

“…Among them, CO is the most critical one, since even 10 ppm of CO in the feedstock can deactivate the platinum group metal (PGM) catalysts in a PEMFC anode, , limiting the credibility of this technology . So far, various technologies have been developed for hydrogen purification. − CO preferential oxidation (COPrOx) in H 2 -rich gas is considered as one of the most efficient and straightforward methods for CO elimination. Apart from precious metals (e.g., Pt and Au) that are typically used as catalysts, non-noble metal oxides (e.g., Cu and Co oxides), pure or combined with other elements, have shown excellent activity of CO oxidation in the presence of H 2 . − Among them, cobalt oxide has attracted wide attention due to its high intrinsic activity toward CO oxidation. , …”

Hydrogen-Rich Gas Production by Catalytic Decomposition of Oxygenated Compounds of C1 Chemistry

“…Ever-increasing role of modern electronic devices in the human life stimulates active research and development in low-power fuel cell based portable and autonomous power units [1,2]. The fuel for such power units is hydrogen or hydrogen-rich gas, which can be produced by reforming hydrocarbons or oxygenates [3][4][5][6]. A literature survey of current studies shows that oxygenated compounds of C1 chemistry, such as formic acid (FA) [7][8][9], methanol [10,11], dimethyl ether (DME) [12,13] and dimethoxymethane (DMM) [14][15][16][17], can be easily converted into hydrogen-rich gas at relatively low temperatures as compared to conventional hydrocarbon fuels.…”
