“…Common applications of this sorption enhanced reactive process include esterifications [10][11][12][13], ester hydrolysis [14,15], etherifications [16] and acetalisations [17][18][19][20]. In most of the aforementioned works, advantage is taken from the sorption and catalytic properties of ion exchange resins.…”

“…The framework for analysis of a coupled reaction and adsorption operation has been well‐developed . The selectivity of gas‐phase reactions, such as steam methane reforming, and liquid phase esterification reactions, has been shown to benefit from the incorporation of an adsorbent in the reactor. A similar process has been developed for the aqueous phase isomerization of glucose to fructose .…”

5-hydroxymethylfurfural (HMF) can be produced from the acid-catalyzed dehydration of fructose but its yield is limited due to subsequent HMF degradation to side products. A reactive adsorption process is proposed to improve the yield to HMF. Separate experimental singlecomponent isotherms of fructose, HMF, formic acid, and levulinic acid on carbon BP2000 and reaction kinetics of the fructose dehydration to HMF in aqueous solution of HCl are presented to develop empirical isotherms and kinetic rate constants, respectively. These sub models are subsequently integrated in an adsorptive reactor at a range of temperatures (100-180°C) with different loadings of adsorbent. It is shown that the adsorbent improves HMF yield compared to the single solution phase (adsorbent-free case). Low temperatures and high adsorbent loadings improve HMF yield. Under certain conditions both reactive adsorption and the commonly used reactive extraction can result in a similar improvement in HMF yield. HMF recovery from the solid adsorbent has been identified as a major challenge that can be ameliorated through

“…These effects should be considered in the process scale-up because the increase of the column diameter can render the system nearly adiabatic [11]. The heat is also generated or consumed due to the enthalpies of adsorption and mixing.…”

Thermal Effects on the Synthesis of 1,1‐Dibutoxyethane in a Fixed‐Bed Adsorptive Reactor

The effects of temperature on the synthesis of 1,1-dibutoxyethane (DBE) in a fixedbed adsorptive reactor were studied by performing both adsorption/desorption and reaction/regeneration experiments at 15 and 35°C. The Langmuir-type isotherm parameters at 15 and 35°C were obtained from the adsorption/desorption experiments. The reaction/regeneration experiments showed an increase in both conversion and productivity with increasing temperature. Isothermal and nonisothermal mathematical models were used to simulate the reactor operation with different Damköhler numbers. The simulated results suggest that the reactor productivity can be improved by using the adiabatic operation mode on the fixedbed adsorptive reactor, obtaining a productivity for DBE of 71.8 mol kg -1 h -1 .
