“…It has been referred in the literature that it is extremely important to set the correct liquid flow direction, which should be based on the different species densities; bottom‐up or top‐down direction must be used to ensure that the component above the front is less dense than the component below the front. This condition avoids a possible axial backmixing phenomenon driven by natural convection .…”

The butyl acrylate synthesis from the esterification reaction of acrylic acid with 1‐butanol in a fixed‐bed adsorptive reactor packed with Amberlyst 15 ion exchange resin was evaluated. Adsorption experiments were carried out with nonreactive pairs at two temperatures (323 and 363 K). The experimental results were used to obtain multicomponent adsorption equilibrium isotherms of Langmuir type. Reactive adsorption experiments using different feed molar ratios and flow rates were performed, at 363 K, and used to validate a mathematical model developed to describe the dynamic behavior of the fixed‐bed adsorptive reactor for the butyl acrylate synthesis. Due to the simultaneous reaction and separation steps, it was possible to obtain a butyl acrylate maximum concentration 38% higher than the equilibrium concentration (for an equimolar reactants ratio solution as feed at a flow rate of 0.9 mL min−1 and 363 K) showing that sorption‐enhanced reaction technologies are very promising for butyl acrylate synthesis. © 2014 American Institute of Chemical Engineers AIChE J, 61: 1263–1274, 2015

“…In addition to the use in the esterification of FFAs in vegetable oils and animal fats, heterogeneous acid catalysts for biodiesel synthesis could in principle be employed to catalyze the simultaneous reactions of TGs and FFAs with low molecular alcohols in transesterification and esterification, respectively [3]. Among the heterogeneous acid catalysts studied to date for trans/esterification are zeolites [4,5], MCM-41 [6,7], tungstated zirconia [8][9][10], sulfated zirconia [11][12][13][14], Amberlyst-15 [15][16][17] and Nafion [18][19][20][21][22]. Some common problems with solid acid catalysts have been: low acid site concentrations, microporosity, hydrophilic character of catalyst surfaces, and active site leaching.…”

A novel sulfonated carbon composite solid acid was successfully prepared by the pyrolysis of a polymer matrix impregnated with glucose followed by sulfonation. The title catalyst has higher acid site density, better esterification activity of both small and large free fatty acids (acetic acid and palmitic acid), and better reusability than the previously reported carbon-based catalyst prepared by sulfonating pyrolyzed sugar. This catalyst also exhibited higher esterification activity than tungstated zirconia (WZ) and Silica-Supported Nafion (Nafion Ò SAC-13). The higher activity of the sulfonated carbon composite solid acid catalyst was clearly due to the presence of a much higher acid site density than any of the other catalysts.

Chemical Industries are primarily intended for conversion of raw materials into desired products. It develops new products for human lives. The challenge for chemical companies is to cut their costs. The chemical industries have high rate of technological change. Chemical industries use separate processes for converting raw material into product. Now day's the technology that is adopted is reactive separation. In this technology, the emphasis is given on combining separate units in one single unit. Advantageous of this technology is like reducing energy use, increase efficiency etc. Reactive separation uses different techniques like Reactive Chromatography, Reactive Distillation and Reactive Extraction, Reactive Membrane Separation, Reactive Crystallization. Out of this, Reactive chromatography is a attractive alternative since it employs differences in adsorption -desorption of chemical reagents on external solid phase, which can also act as catalyst. It is possible to obtain high purity of product from this process, also downstream purification is reduced or even eliminated. Fixed bed reactor or simulated bed reactors are mainly used for this purpose. Many researchers have studied reactive chromatography. This review is focused in development in reactive chromatography processes.
