“…These works predominantly differed in the configurations and type of the reactors used and the reaction byproduct(s) adsorbed (i.e., CH 3 OH and/or H 2 O). Westerterp and co-workers , introduced a solid adsorbent in methanol reactor to obtain higher yield and reaction conversions. They used a gas–solid–solid trickle flow reactor (GSSTFR) with silica–alumina adsorbent for capturing methanol product from the reaction gas mixture.…”

To counter the equilibrium limitations in traditional methanol production from synthesis gas, a periodic and sorptionenhanced methanol synthesis process (SE-MeOH) with in situ removal of water byproduct is designed and optimized. A generalized reaction−adsorption modeling and simulation framework is coupled with a simulation-based constrained gray-box optimizer to obtain the optimal cycle configuration, design parameters, process specifications, and operating conditions. The best-case results indicate that SE-MeOH processes can break the barrier of the current limit of industrial methanol yield and improve it by 55−87% with a slight compromise (9−46%) on CH 3 OH production capacity. This tradeoff is a result of periodic operation which is required for sorption enhancement. The techno-economic optimization of a base industrial reactor also leads to more than 7% improvement in methanol yield with only 2% decrease in production capacity while keeping the cost of syngas-to-methanol production competitive. The SE-MeOH system is further optimized through varying the feed specifications and number of reactor tubes. The results suggest that the synthesis gas composition, flow rate, and number of tubes are the major factors in determining methanol process performance.

“…There are several opportunities to circumvent the limitations imposed by thermodynamic equilibria and they mainly involve in situ removal of methanol. This can be done, for example, by methanol adsorption on fine alumina powder or dissolving methanol in tetraethylene glycol, n-butanol, or n-hexane [33][34][35]. Another method involves in situ condensation at a cooler inside the reactor [36].…”

“…Following the pioneering work of Kuczynski et al on adsorptive methanol synthesis 3, numerous publications subsequently appeared concerning simplified hydrogen production processes 4, 5. Important contributions to the development of adsorptive reactors were made by the group of Rodrigues at the University of Porto in Portugal and of Alpay at the Imperial College London, in which they really attempted to develop favorable concentration‐temperature trajectories, fixed‐bed structuring strategies, and appropriate regeneration procedures 6–11.…”

Adsorptive reactors represent a promising genre of multifunctional reactors combining the highly compatible adsorptive and reactive functionalities. Although they offer multiple benefits to the overall process flowsheet, overcoming the low space time yields, which are an inherent drawback of their cyclic operation, and unwanted functionality interference remain a challenge. The potential of temperature profiling to expedite the macrostructuring of adsorptive reactors for performance optimization is presented. Two industrially relevant reactions have been investigated as test cases: the Claus reaction for recovering sulfur from acid gas and the Deacon reaction for the plant‐internal recycling of chlorine via HCl oxidation.
