“…In the recent decades, ILs have been described as catalysts (Cheng et al, 2022;Han et al, 2022;Lima et al, 2022), solvents (Muhammad et al, 2015a) and media for biocatalysis (Arai et al, 2010;Ruzich & Bassi, 2010;Zhao et al, 2010) in biodiesel synthesis (Muhammad et al, 2015b). The utility of microwave irradiation (MW) to carry out organic reactions has now become a regular feature, as shown by the increasing number of reviews and books (Kappe et al, 2012;Martinez-Palou, 2006).…”

“…Besides, biodiesel production via transesterification methods can be conducted using various types of feedstocks that contain free fatty acids and/or triglycerides [6]. Various edible oil was used for biodiesel production, including canola oil [7][8], rapeseed oil [9], peanut oil [10], sunflower oil [11][12], coconut oil [13], palm oil [14][15], and safflower oil [16]. However, utilizing edible sources for biodiesel production led to ecological imbalances and deforestation.…”

Biodiesel production from non-edible oil is an alternative way to reduce edible oil dependency and reduce the competition for feed and food. Candlenut oil (Aleurites moluccana L.) is one of the non-edible oils which can be used as feedstock for biodiesel production since they have a high oil content. Herein, the biodiesel production from candlenut oil has been conducted using zinc oxide (ZnO) synthesized by the polyol method. Polyol methods facilitated the formation of ZnO nanoparticles with various shapes, including spherical, rod, and hexagonal. Besides, ZnO showed a mesoporous characteristic, facilitating the conversion of fat fatty acid to fatty acid methyl ester (FAME) of 61%. Increasing ZnO dosage led to enhancing the FAME yield. Similarly, the FAME yield was also improved by increasing the reaction time. The results of esterification of candlenut oil and methanol yielded 70.76% FAME with 2% nano-ZnO polyol catalyst at 180 min reaction time at room temperature whilst being stirred constantly at 400 rpm. A good FAME conversion using ZnO at room temperature provides good information to produce biodiesel with a simple method. Apart from that, photocatalytic promoted transesterification at room temperature, which is beneficial for reducing energy consumption.

“…There is rapid growth in the cost of crude oil around the world as well as its extraction processes; this is in addition to the extensive and controlled consumption of common traditional fossil fuels [1,2]. Moreover, the consumption of these fuels is associated with serious environmental concerns, which are related to the immense emissions of the essential greenhouse gases and their side impacts on the climate change phenomenon [3,4].…”

Egyptian kaolinite was applied in the synthesis of zeolite-A by conventional hydrothermal and alkali fusion methods, resulting in two forms of zeolite-A: the hydrated phase (H.ZA) and the dehydrated phase (DH.ZA). The DH.ZA phase exhibits an enhanced surface area (488 m2/g), total basicity (7.73 mmol OH/g), high sodium content (20.2%), and a narrow particle size distribution (5 to 25 µm) as compared to the H.ZA phase (423 m2/g surface area, 5.88 mmol OH/g total basicity, 13.3% sodium content, and 10 to 45 µm particle size distribution). DH.ZA exhibits enhanced catalytic activity, achieving a biodiesel yield of 96.8% after 60 min at 60 °C, while the application of H.ZA resulted in a 95.8% yield after 120 min at 80 °C. The controlled transesterification mechanism in the presence of H.ZA and DH.ZA involved robust base-catalyzed reactions. The reactions follow the pseudo-first-order kinetics, and the rate constants (Kc) were determined at three different temperature values (40, 50 and 60 °C). The activation energies using H.ZA (35.9 kJ.mol−1) and DH.ZA (32.714 kJ.mol−1) demonstrates their efficiencies in mild conditions. The thermodynamic parameters of enthalpy (33.23 kJ.mol−1 (H.ZA) and 30.03 kJ.mol−1 (DH.ZA)), Gibb’s free energy (65.164 kJ.mol−1 (H.ZA) and 65.268 kJ.mol−1 (DH.ZA)), and entropy (−195.59 J.K−1.mol−1 (H.ZA) and −195.91 J.K−1.mol−1 (DH.ZA)) demonstrate the spontaneous and endothermic behaviours of these reactions. The obtained biodiesel matches the physical properties of the international standards, and the recyclability properties of the two zeolite phases demonstrate their suitability for commercial-scale applications.
