“…In the process of biodiesel production, time, temperature, type and amount of used catalyst, mixing intensity, alcohol and oil type and their molar ratio are the effective parameters of reaction efficiency. Using microreactors, due to the high surface-to-volume ratio, the oil and alcohol feeds are mixed in a micro-sized channel, resulting in better mass transfer between two immiscible phases [ 18 ].…”

The statistical experimental design (DoE) and optimization (Response Surface Methodology combined with Box–Behnken design) of sunflower oil transesterification catalyzed by waste chicken eggshell-based catalyst were conducted in a custom-made microreactor at 60 °C. The catalyst was synthesized by the hydration–dehydration method and subsequent calcination at 600 °C. Comprehensive characterization of the obtained catalyst was conducted using: X-ray powder diffractometry (XRD), X-ray fluorescence (XRF), Fourier-transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), N2 physisorption, and Hg-porosimetry. Structural, morphological, and textural results showed that the obtained catalyst exhibited high porosity and regular dispersity of plate-like CaO as an active species. The obtained optimal residence time, catalyst concentration, and methanol/oil volume ratio for the continuous reaction in microreactor were 10 min, 0.1 g g−1, and 3:1, respectively. The analysis of variance (ANOVA) showed that the obtained reduced quadratic model was adequate for experimental results fitting. The reaction in the microreactor was significantly intensified compared to a conventional batch reactor, as seen through the fatty acid methyl esters (FAMEs) content after 10 min, which was 51.2% and 18.6%, respectively.

“…It can help in solving the complex flow problems especially when it is hard to see with naked eyes what's going on in the process reactor (Mohd Tamid et al, 2011). Santana et al applied the CFD analysis in their design optimization of microchannel for biodiesel synthesis (Santana et al, 2019a). The introduction of obstruction with different types of geometry such as triangular baffle (Santana et al, 2019b) or circular obstruction (Santana et al, 2018) further enhance the mixing of oil and alcohol in the microchannel reactor with the help of a CFD tool (Elsholkami et al, 2016).…”

“…The enzymatic treatments of soapstock described here (for biodiesel, as well as for fine chemicals synthesis) could more advantageously meet large scale and high productivity by means of continuous-flow reactors. The principles of flow chemistry have been applied also to biocatalysis very successfully, and many papers and reviews have been published concerning the matter, especially connected to lipase-mediated reactions for biodiesel production [73][74][75][76][77][78].…”

The review will discuss the methods that have been optimized so far for the enzymatic hydrolysis of soapstock into enriched mixtures of free fatty acids, in order to offer a sustainable alternative to the procedure which is currently employed at the industrial level for converting soapstock into the by-product known as acid oil (or olein, i.e., free fatty acids removed from raw vegetable oil, dissolved in residual triglycerides). The further biocatalyzed manipulation of soapstock or of the corresponding acid oil for the production of biodiesel and fine chemicals (surfactants, plasticizers, and additives) will be described, with specific attention given to processes performed in continuous flow mode. The valorization of soapstock as carbon source in industrial lipase production will be also considered.
