A small heat of reaction limits the efficiency of the catalytic hydrogenation of CO2 to form methanol; an improved efficiency can be achieved by shifting the thermodynamic equilibrium toward the formation of methanol. The exothermic adsorption of the products in sorption catalysts is shown to increase the reaction yield. The sorption catalysts consist of catalytically active Cu particles incorporated into a zeolite, which is known to strongly absorb water. In addition to high reaction yield of methanol, the sorption catalyst reduces CO2 to CO and dimethyl ether. An enhancement factor of up to 400% for CO and 130% for methanol and dimethyl ether at a relatively low pressure of 15 bar is shown. Furthermore, the following relevant parameters for future technical realization are derived: a high catalytic activity and the reversible adsorption of the products at reaction conditions. A key experiment that combines a catalytic reaction and a pressure swing desorption is presented and demonstrates the feasibility of sorption‐enhanced catalysis for efficient energy use in large‐scale reactors.

A methodology is proposed to reduce the cost and capital intensity of small-scale chemical processes by creating new opportunities for economies of numbers through standardizing the equipment designs across multiple processes. We depart from asynchronous design of single-processes and adopt a common-functionality based simultaneous design of multiple processes that use similar unit operations. A generalized cost function is used to appropriately balance the trade-offs between economies of scale and economies of numbers. An optimization-based framework for design standardization is developed and illustrated using two case studies. The first involves the simultaneous synthesis of methanol and ammonia processes, and the second addresses the optimal synthesis of multi-column natural gas liquid (NGL) fractionation processes for different natural gas sources. We observe that considerable reduction in capital intensity of small-scale processes is possible through equipment standardization.

“…Additionally, the tube-cooled reactor is also an option for this process [51]. Other novel reactors focusing on the in situ condensation and removal of the produced water and methanol, e.g., by using membrane reactors [39,52], sorption-enhanced [53,54] and natural convection [55] processes, are also reported at research level. However, hydrogenation of CO 2 to methanol by reaction 2 introduces more water, which has a detrimental effect on the conventional Cu-based catalyst [56].…”

A Review of The Methanol Economy: The Fuel Cell Route

et al. 2020

View full text Add to dashboard Cite

This review presents methanol as a potential renewable alternative to fossil fuels in the fight against climate change. It explores the renewable ways of obtaining methanol and its use in efficient energy systems for a net zero-emission carbon cycle, with a special focus on fuel cells. It investigates the different parts of the carbon cycle from a methanol and fuel cell perspective. In recent years, the potential for a methanol economy has been shown and there has been significant technological advancement of its renewable production and utilization. Even though its full adoption will require further development, it can be produced from renewable electricity and biomass or CO2 capture and can be used in several industrial sectors, which make it an excellent liquid electrofuel for the transition to a sustainable economy. By converting CO2 into liquid fuels, the harmful effects of CO2 emissions from existing industries that still rely on fossil fuels are reduced. The methanol can then be used both in the energy sector and the chemical industry, and become an all-around substitute for petroleum. The scope of this review is to put together the different aspects of methanol as an energy carrier of the future, with particular focus on its renewable production and its use in high-temperature polymer electrolyte fuel cells (HT-PEMFCs) via methanol steam reforming.
