Abstract

Steam reforming of methanol has been studied over various copper-based catalysts at temperatures from 443 to 533 K. Screening experiments showed that a coprecipitated CuO-ZnO-Al₂O₃ low-temperature methanol synthesis catalyst had the highest activity and did not deactivate with time on line. It also exhibited 100% selectivity to carbon dioxide and hydrogen (the desired reaction products). Kinetic measurements made over the coprecipitated CuO-ZnO-Al₂O₃ were found to fit the power law expression: r_SR=k₀e^{–105kJ/mol/RT}P^0.26_MeOHP^0.03_H₂OP^–0.2_H₂ Carbon dioxide was found to have no effect on the kinetics of steam reforming of methanol. When carbon monoxide was added to the feed there was negligible influence on the steam reforming reaction with an order of 0.016 being observed.

Insights into direct/synergetic processes for high-efficiency steam reforming of methanol over Pt-In<inf>2</inf>O<inf>3</inf>/CeO<inf>2</inf> catalysts: The effect of support structural properties
2024, Fuel
The addition of Pt (1 %) and In₂O₃ (7 %) phases into CeO₂ supports exhibited an interaction, resulting in the formation of bifunctional Pt²⁺-In₂O₃-CeO₂, Pt^δ+-CeO₂ (0 < δ < 2), In₂O₃-CeO₂, and inactive In₂O₃ macroparticles., Low CO selectivity was achieved in methanol steam reforming (MSR) by sacrificing methanol conversion/catalytic stability. Two distinct reaction paths were identified, viz., the direct process over bifunctional Pt²⁺-In₂O₃-CeO₂ and the synergetic process between Pt^δ+-CeO₂ and In₂O₃-CeO₂. The relative ratio of these two processes played a decisive role in determining the product distribution. The direct process improved methanol conversion while maintaining low CO selectivity. However, a decrease in catalytic stability was attributed to the agglomeration and sintering of the In₂O₃ phase, leading to the conversion of Pt²⁺-In₂O₃-CeO₂ into Pt^δ+-CeO₂. To address the challenge of balancing methanol conversion/catalytic stability and CO selectivity, it was crucial to enhance Pt²⁺-In₂O₃-CeO₂ sites and preserve their stability. Furthermore, the structural properties of the support played a significant role in governing the distributions and states of Pt and In₂O₃ phases. Specifically, the use of CeO₂ (0.5 °C min⁻¹) support resulted in a substantial increase in Pt²⁺-In₂O₃-CeO₂ and effectively mitigated the sintering of In₂O₃ phases, ensuring the stability of Pt²⁺-In₂O₃-CeO₂. In conclusion, our work elucidated the intricate relationships among the structural properties of CeO₂ supports, the distributions and states of Pt and In₂O₃ phases, and MSR performance over Pt-In₂O₃/CeO₂ catalysts, which hold promise for advancing the development of high-performance MSR catalysts.
Hydrogen production from steam reforming of methanol: A comprehensive review on thermodynamics, catalysts, reactors, and kinetic studies
2024, International Journal of Hydrogen Energy
The depletion of fossil fuels such as oil, natural gas, and coal, as well as environmental concerns, pave the way for the effective utilization of renewable energy sources. Hydrogen is forecasted as an energy alternative which can be utilized at high conversion causing zero or near-zero emission at the point of use. Methanol is an ideal hydrogen carrier owing to its low cost, high H/C ratio, low reforming temperature, no sulfur content and liquid state at ambient conditions and it can be produced from a variety of feedstocks. This review article provides an overview of the various catalysts employed in steam reforming of methanol (SRM). It delves into the effect of catalyst preparation methods and catalyst composition on the catalytic activity and selectivity for SRM. Thermodynamic analysis, the reaction schemes and kinetics over various catalysts used in SRM were discussed in detail. Various reactors used for SRM, including conventional packed bed, microchannel and membrane reactors were thoroughly reviewed and discussed.
Hydrogen generation using methanol steam reforming – catalysts, reactors, and thermo-chemical recuperation
2024, Renewable and Sustainable Energy Reviews
Hydrogen is a promising replacement for fossil fuels since it can be produced using renewable resources. However, hydrogen storage and transportation are the two significant barriers to the implementation of hydrogen-fuelled energy systems. Nevertheless, this issue can be solved by producing hydrogen on-board by methanol steam reforming. Methanol has a higher hydrogen/carbon ratio when compared to other hydrocarbons and it can be obtained from renewable sources such as biomass and stored and carried on-board. Further, the addition of hydrogen/hydrogen-rich reformates as secondary fuel can significantly improve the efficiency of internal-combustion engines and reduce emissions. In methanol-reformation, the type of catalyst and reactor design affect hydrogen yield and selectivity. This review focuses on the recent advancements in developing catalysts and reactors for methanol steam reforming and integration of methanol-reformers with internal-combustion engines for on-board production of hydrogen and its utilization as a secondary fuel. Different catalysts and their synthesis methodologies, promotors, and additives adopted for methanol reformation are compared. The applicability of novel catalysts such as spinels, perovskites and metal-organic frameworks is scrutinised. Moreover, the active sites involved, and mechanistic pathways are investigated. Additionally, the merits and demerits of conventional fixed-bed reactors, and the structural features and the benefits of micro-reactors studied are critically analysed. The integration of a methanol-reformer with an internal-combustion engine exhaust through a heat exchange system, a technique known as thermo-chemical recuperation and the influence of hydrogen-rich reformates on engine performance, thermal efficiency and emissions are deliberated.
Dissecting ZnO<inf>X</inf>/Cu interfacial self-encapsulation and methanol-induced strong metal-support interaction of the highly active alloyed CuZn and ZnO for methanol steam reforming
2024, Fuel
A highly durable non-noble metal catalyst like copper for high-temperature methanol steam reforming is necessary for a compact hydrogen reactor. Herein, deactivation of copper-based catalysts with strong metal-support interaction is extremely sluggish even at 550 °C when using a selective chemical reduction approach paired with various induced activation procedures. The adsorbate methanol could enhance the migration of ZnOx onto the Cu and increase the number and electronic modulation of high-activity CuZn alloy sites. The Zn pre-deposited on the Cu surface induces continuous morphology and structural reorganization of the catalytic surface, which constantly refreshes the catalyst surface. The adsorbate methanol led to abundant CuZn alloy-ZnO synergism, which sped up the dissociation of·H₂O and the dehydrogenation of *CH₃O in accordance with the density functional theory and, ultimately, exhibited the highest methanol conversion (99.55 %) and hydrogen yield (97.73 %) compared to the hydrogen induction.

Fuel processing systems
2023, Modelling of Chemical Process Systems
This chapter of this book deals with fuel processing systems for application in fuel cell technology. There are various types of fuel cells that are under research stage or are already commercialized. A fuel cell system, in addition to the stack, contains a number of other components called balance of plant (BoP). A fuel processing unit is probably one of the most important BoP that is integral to the stable operation of the fuel cell. The purpose of the fuel processing system is to produce fuel from primary sources that can be electrochemically oxidized in a fuel cell without causing appreciable performance loss of the cell. The fuel quality requirements are different for different fuel cell types as some fuel cell types are capable of tolerating impurities to a higher level without undergoing appreciable performance degradation. However, it is very important to understand the operating limits of a particular fuel cell type with respect to the concentration of impurities it can tolerate so that appropriate fuel processing units can be designed. The more stringent the fuel quality requirements are, the more expensive the fuel processing becomes. The discussion in this chapter is mostly focused on fuel quality requirements and fuel processing of common fuels for polymer electrolyte membrane fuel cell (PEMFC) and Solid Oxide Fuel Cells (SOFCs) as they attract significant attention from the fuel cell community.
