“…However, no publications were found in this topic apart from the one we published (Agirre et al, 2011b). The continuous water removal from the reaction mixture shifts the reaction to the product side obtaining higher conversions that the achievable ones in conventional reactors.…”

“…In esterification processes, where the pervaporation unit is not integrated in the reaction unit, most of the articles report the use of commercial polymeric dehydration membranes (Benedict et al, 2006;Domingues et al, 1999;Sanz & Gmehling, 2006a;Sanz & Gmehling, 2006b), whereas in those processes where the reaction and the separation are combined in one single reactor polymeric, ceramic and polymeric/ceramic membranes are applied (Bagnell et al, 1993;Bernal et al, 2002;Peters et al, 2005;Peters et al, 2007;Zhu et al, 1996). As an example, the acetalization of ethanol with butanal was carried out using the second configuration, i.e., placing a passive membrane in a reactor (Agirre et al, 2011b) showing a good behavior. In this work a hybrid silica membrane (HybSi ® , developed at ECN) for dehydration was used.…”

Abstract:The development of processes based on the integration of new technologies is of growing interest to industrial catalysis. Recently, significant efforts have been focused on the design of catalytic membrane reactors to improve process performance. In particular, the use of membranes, that allow a selective permeation of water from the reaction mixture, positively affects the reaction evolution by improving conversion for all reactions thermodynamically or kinetically limited by the presence of water. In this paper, how pervaporation (PV) and vapor permeation (VP) technologies can improve the catalytic performance of reactions of industrial interest is considered. Specifically, technological approaches proposed in the literature are discussed with the aim of highlighting advantages and problems encountered in order to address research towards the optimization of membrane reactor configurations for liquid biofuel production in large scale.

“…Acetaldehyde and 1,2-propylene glycol can be recovered and purified via the reverse hydrolysis reaction. High yield of 2,4-dimethyl-1,3-dioxolane can be obtained in the equilibrium limited reaction by removing the products [11]. Although there have been several studies describing the recovery of aqueous glycol solution via reactive extraction and reactive distillation [12][13][14], systematic experimental data, especially kinetic modeling work, have not been reported.…”

− We investigated catalytic activity of ion-exchange resins in acetalization of 1,2-propylene glycol with acetaldehyde. The impacts of reaction variables, such as temperature, reaction time, catalyst loading and feedstock composition, on the conversion of 1,2-propylene glycol were measured. The life of the catalyst was also studied. Furthermore, the reaction kinetics of 1,2-propylene glycol acetalization was studied. It was found that reaction rate followed the firstorder kinetics to acetaldehyde and 1,2-propylene glycol, respectively. Therefore, overall acetalization reaction should follow the second-order reaction kinetics, expressed as .
