Optimizing the Production of Biodiesel from Waste Cooking Oil Utilizing Industrial Waste‐Derived MgO/CaO Catalysts

Abstract

Biodiesel manufacturing using waste cooking oil is a cost‐effective method for lowering the costs of production. Composites composed of CaO and MgO recovered from industrial waste may be utilized to create ecologically heterogeneous transesterification catalysts. The activity of the catalysts and the impacts of calcination temperatures and various weight percentages were examined. The efficiency of the MgO/CaO catalyst for producing biodiesel from waste cooking oil was studied under optimum conditions. The properties and structure of the catalysts were characterized by scanning electron microscopy, X‐ray diffraction, and Fourier transform infrared, which proved the acceptable performance of the catalysts for transesterification of waste cooking oil.

A Review of the Emission, Performance, Combustion, and Optimization Parameters in the Production of Biodiesel from Waste Cooking Oil

“…These independent variables all exhibited high significance according to the significance test [55]. The MgO/CaO composite catalysts based on industrial waste materials were prepared as a heterogeneous catalyst in the production of biodiesel from WCO by Aghel et al [56]. The optimum conditions required for maximum biodiesel yield was investigated.…”

“…The result showed a 9 wt.% catalyst concentration, 63 C reaction temperature, and 2:1 methanol to oil molar ratio produced the maximum activity with the FAME percent greater than 93.32%. The catalytic activity of the catalysts increased progressively when the calcination temperature was increased [56]. Helmi et al [57] studied a novel reusable heterogeneous catalyst based on the immobilization of phosphomolybdic acid (HPMo) on graphene oxide substrate (HPMo-GO) and also investigated the optimum conditions for obtaining the highest biodiesel yield.…”

Carbon Nitride-Based Nanomaterials as a Sustainable Catalyst for Biodiesel Production

“…Many countries, such as the United States and Brazil, have CO 2 reduction target of 50% by 2030 compared to 2005 emissions, aiming to reach carbon neutrality by 2050 . In this sense, environmental concerns have sparked interest in the discovery and development of alternatives to green, sustainable, eco-friendly, and renewable fuel-derived energy. , Biodiesel fuel production is one of the most promising sustainable alternatives to replace non-renewable liquid fossil fuels, due to renewable and environment-friendly features, high flash point, good safety, and excellent lubricity . Policies for greater inclusion of biodiesel in fossil fuels are already being used.…”

“…4,5 Biodiesel fuel production is one of the most promising sustainable alternatives to replace non-renewable liquid fossil fuels, due to renewable and environment-friendly features, high flash point, good safety, and excellent lubricity. 6 Policies for greater inclusion of biodiesel in fossil fuels are already being used. For example, Brazil determined an increase in the use of biodiesel blend concentration from 8% in 2018 to 15% in 2023 with diesel fuel.…”

Super rapid preparation of biodiesel over highly dispersed K2CO3 supported by LDH

“…The acceptable performance of the catalysts in the esterification of waste cooking oil was demonstrated by characterization. 11 In the above study, there are problems in controlling pH, high reaction temperature, long reaction time, and complicated operation. This paper addresses a series of problems to improve and optimize the reaction to promote rapid ester exchange reaction.…”
