“…Priambodo et al. () obtained a 93% biodiesel conversion efficiency for WCO using commercial strontium oxide (SrO), 40 to 180 seconds of reaction time, a reaction temperature of around 80°C, a 6:1 methanol‐to‐oil ratio, and a microwave power output of 1000 watts (W). Wang, Lee, and Chen () investigated microwave‐ and reflux‐assisted transesterification in methanol with alkali‐loaded low‐aluminum ( Al) Zeolite Beta as a catalyst and obtained a final conversion yield of more than 90% within an hour of reflux reaction.…”

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.

“…SathyaSelvabala et al (2011) melakukan proses dua tahap untuk menghasilkan biodiesel dari minyak nyamplung menggunakan katalis asam padat dimodifikasi zeolite untuk langkah pretreatment diikuti oleh reaksi transesterifikasi berkatalis KOH. Penggunaan microwave dilakukan oleh Priambodo et al (2015) pada reaksi transesterifikasi minyak goreng segar dan minyak goreng bekas. Faktor utama yang mempengaruhi proses transesterifikasi adalah rasio molar metanol terhadap minyak, jumlah katalis dan waktu reaksi.…”

Minyak nyamplung (Calophyllum inophyllum Linn) adalah salah satu bahan baku yang potensial untuk produksi biodiesel karena kandungan minyaknya yang tinggi. Minyak nyamplung mengandung asam lemak bebas yang tinggi, proses pretreatment dalam penelitian ini dapat mereduksi asam lemak bebas dari 27,978 % menjadi 1,269% sehingga minyak dapat dilanjutkan pada proses transesterifikasi. Tujuan penelitian ini untuk mengidentifikasi metil ester dalam produk, mengkaji kinetika reaksi pembuatan biodiesel dan mengkaji pengaruh penggunaan iradiasi microwave terhadap energi aktivasi dan laju reaksi transesterifikasi dibandingkan dengan metode konvensional. Power microwave (100, 200 dan 400W), waktu iradiasi (5, 7, 10, 12 dan 15 menit) dan suhu reaksi (50, 55, 60, 65 dan 70 oC) digunakan sebagai parameter penelitian. Kondisi operasi terbaik menggunakan power microwave 200W pada suhu 65 oC selama 5 menit, yield biodiesel maksimal sebesar 84,62% dan sifat fisik biodiesel telah memenuhi standar SNI 04-7182-2006, ASTM 6751-02 dan EN-14214. Biodiesel nyamplung mengandung 30,23% metil oleat, 25,76% metil linolelaidat, 19,21% metil palmitat, 15,75% metil stearat, 2,11% metil lignocerat, 1,41% metil eicosanoic, 0,54% metil behenate dan 0,37% metil palmitoleat. Biodiesel nyamplung dengan iradiasi microwave memiliki energi aktivasi (Ea) sebesar 2579,834 J/mol, faktor tumbukan (A) sebesar 1,0161 L/mol menit, laju reaksi transesterifikasi (rt) = 1,0161e(-2579,834/RT) [ME] dan waktu reaksi selama 5 menit. Sedangkan biodiesel nyamplung dengan metode konvensional memiliki energi aktivasi (Ea) sebesar 4831,265 J/mol, faktor tumbukan (A) sebesar 0,3772 L/mol, laju reaksi transesterifikasi (rt)=0,3772 e(-4831,265/RT)[ME] dan waktu reaksi selama 30 menit. Hasil penelitian menunjukkan penggunaan iradiasi microwave dapat meningkatkan laju reaksi transesterifikasi, menurunkan energi aktivasi dan mengurangi waktu reaksi menjadi 1/6 kali lebih cepat dibandingkan metode konvensional.

“…The activity of base catalysts is higher than that of acid catalysts for both homogeneous and heterogeneous catalysts, and the reaction occurs under milder conditions. However, base catalysts cause the problem of a side saponification reaction that occurs in the presence of FFA [ 15 ]. The heterogeneous base and acid catalysts are much easier to separate from the product, and allow the performance of continuous processes or reuse of the catalysts in batch regimes [ 16 , 17 ].…”

Sol–Gel Entrapped Lewis Acids as Catalysts for Biodiesel Production

et al. 2020

Replacing fossil fuels with biodiesel enables the emission of greenhouse gases to be decreased and reduces dependence on fossil fuels in countries with poor natural resources. Biodiesel can be produced by an esterification reaction between free fatty acids (FFAs) and methanol or by transesterification of triglycerides from oils. Both reactions require homogeneous or heterogeneous catalysis. Production of biodiesel catalyzed by heterogeneous catalysts seems to be the preferred route, enabling easy product separation. As we have previously shown, the Lewis acids AlCl3 and BF3 can serve as highly efficient catalysts under ultrasonic activation. The present study focused on the development of oleic acid (OA) esterification with methanol by the same catalysts immobilized in silica matrices using the sol–gel synthesis route. During the course of immobilization, AlCl3 converts to AlCl3 × 6H2O (aluminite) and BF3 is hydrolyzed with the production of B2O3. The immobilized catalysts can be reused or involved in a continuous process. The possibility of biodiesel production using immobilized catalysts under ultrasonic activation is shown for the conversion of FFAs into biodiesel in batch and continuous mode.
