“…Conventional homo-catalysts are broadly used for industrial-level production [ 15 ]. Though they offer a higher yield, numerous demerits are coupled with higher production, i.e., the requirement of excess methanol [ 16 ], steps of neutralization that require considerable time and effort, and washing and drying steps to remove glycerol and catalysts which increases the cost of the product and also wastage of water [ 17 , 18 ]. Due to their possible part in challenging the disadvantages of standardized homogeneous catalysts, heterogeneous catalysts are receiving much interest for synthesizing biodiesel.…”

We confined the formation and characterization of heterogenous nano-catalysts and then used them to produce biodiesel from the novel non-edible seed oil of Prunus aitchisonii. P. aitchisonii seeds’ oil content was extracted at about 52.4 ± 3% with 0.77% FFA. Three different heterogenous nano-catalysts—calcined (CPC), KPC, and KOH-activated P. aitchisonii cake Titanium Dioxide (TiO2)—were synthesized using calcination and precipitation methods. The mentioned catalysts were characterized through XRD, SEM, and EDX to inspect their crystallin dimension, shape, and arrangement. Titanium dioxide has morphological dimensions so that the average particle size ranges from 49–60 nm. The result shows that the crystal structure of TiO2 is tetragonal (Anatase). The surface morphology of CPC illustrated that the roughness of the surface was increased after calcination, many macropores and hollow cavities appeared, and the external structure became very porous. These changes in morphology may increase the catalytic efficiency of CPC than non-calcined Prunus aitchisonii oil cake. The fuel belonging to PAOB stood according to the series suggested by ASTM criteria. All the characterization reports that P. aitchisonii is a novel and efficient potential source of biodiesel as a green energy source.

“…The tryglycerides react with an alcohol, usually methanol, in the presence of a basic catalyst to give alchyl esters, biodiesel, and glicerol [5,14,15]. The chemical reaction takes place in a batch stirred reactor at temperatures between 60-70 • C for a time of 60 min [5,[16][17][18]. The correct operation of the batch reactor is essential to reach a high yield of the transesterification reaction.…”

Thermal and Fluid Dynamic Analysis within a Batch Micro-Reactor for Biodiesel Production from Waste Vegetable Oil

Biofuels represent an alternative solution to petroleum-based fuels. In particular, biodiesel is very interesting, especially if it is produced from waste vegetable oil. Biodiesel can be used in diesel engines. The aim of this work is to implement a 2D numerical analysis in Comsol Multiphysics in order to verify an uniform temperature field within a non-isothermal batch mixed micro-reactor. An immersion heater system has been studied as a suitable solution to increase the temperature of WVO (Waste Vegetable Oil) before the start of the transesterification reaction. Thus, the efficiency of the immersion heating system has been investigated. The results show that the temperature field is not uniform within the fluid domain, because of the convective flux with the external environment. These conditions could lead to a low overall conversion rate.
