“…An interesting way to overcome the two aforementioned limitations is by intensifying both reaction and downstream separation through the reactive distillation (RD) process for the biodiesel production [7][8][9][10][11][12][13][14][15][16]. Reactive distillation is a unit operation in which the chemical reaction and the product separation occur simultaneously in one unit.…”

“…Regarding the efficiency of the dividing-wall distillation column, it is important to highlight that in a single distillation column, the biodiesel is obtained as bottoms product, the excess of methanol is recovered as distillate product that can be recycled, and the water can be removed in the side stream [14]. Also, the conversion can be increased by using an adsorption system coupled to a reactor, since the removal of water displaces the equilibrium to the products [15].…”

The esterification of oleic acid and methanol using sulfuric acid as a homogeneous catalyst is studied in reactive-separation systems. The conversion of the free fatty acid was investigated in two different experiments with the molar ratio of methanol/oleic acid, amount of catalyst, temperature, and reaction time as variables. The conversion of the free fatty acid was found to depend strongly on the molar ratio of methanol/oleic acid. The reaction time had a direct effect on the conversion of the free fatty acid, and this conversion decreased with higher temperature. These results were valuable for a preliminary study on biodiesel production, using an acid homogeneous catalyst in a reactive dividing-wall distillation column.

“…In addition, the composition profiles indicate that the thermally coupled RD column operates with a lower concentration of water in the reaction zone, which also reduces the catalytic deactivation. Cossio-Vargas et al (2011) explored the production of biodiesel from feedstock mixtures of fatty acids (oleic, linoleic, n-dodecanoic) using sulfuric acid as catalyst in reactive distillation sequences with thermal coupling. Chemical equilibrium was assumed on each reactive tray.…”

Reactive distillation (RD) processes integrate reaction and distillation, the reactants being converted with the simultaneous separation of the products. This chapter describes the use of reactive distillation technology to produce biodiesel by esterification of free fatty acids, or trans-esterification of various oils (triglycerides). An overview of the reported experimental and simulation studies is provided, covering also the process design, dynamics and control, as well as more complex RD configurations based on dividing-wall column technology.Reactive distillation (RD) is especially attractive in systems where certain chemical and phase equilibrium conditions co-exist. The reaction and distillation take place in the same zone of a distillation column, the reactants being converted with the simultaneous separation of the products and recycle of unused reactants. As the products must be separated from reactants by distillation, this implies that the products should be lighter and/or heavier than the reactants. The ideal case is when one product is the lightest and the other product is the heaviest, with the reactants being the intermediate boiling components (Luyben and Yu 2008).
