Abstract
The production of pure hydrogen is one of the most important problems of the modern chemical industry. While high volume production of hydrogen is well under control, finding a cheap method of hydrogen production for small, mobile, or his receivers, such as fuel cells or hybrid cars, is still a problem. Potentially, a promising method for the generation of hydrogen can be oxy–steam-reforming of methanol process. It is a process that takes place at relatively low temperature and atmospheric pressure, which makes it possible to generate hydrogen directly where it is needed. It is a process that takes place at relatively low temperature and atmospheric pressure, which makes it possible to generate hydrogen directly where it is needed. This paper summarizes the current state of knowledge on the catalysts used for the production of hydrogen in the process of the oxy–steam-reforming of methanol (OSRM). The development of innovative energy generation technologies has intensified research related to the design of new catalysts that can be used in methanol-reforming reactions. This review shows the different pathways of the methanol-reforming reaction. The paper presents a comparison of commonly used copper-based catalysts with other catalytic systems for the production of H2 via OSRM reaction. The surface mechanism of the oxy–steam-reforming of methanol and the kinetic model of the OSRM process are discussed.
Highlights
The economic and civilization development of the world has caused the population and the total energy consumption to have increased significantly recently
The kinetic model proposed by the authors is based on the assumption that formate is formed from oxymethylene in the process of partial oxidation of methanol, which determines the reaction rate determining step (RDS)
The results showed that it has the highest methanol conversion and the H2 production rate for oxidative steam reforming of methanol (OSRM)
Summary
The economic and civilization development of the world has caused the population and the total energy consumption to have increased significantly recently. An important aspect of the developed catalysts is their high stability, which they should have in order to be used to power fuel cells applied in mobile vehicles or stationary systems constituting an emergency energy source in public places (including military bases, offices, hospitals, administrative buildings, etc.). Their applicability increases due to their quiet operation, the quality of the supplied energy, the possibility to transport and application practically everywhere
