“…Proses transesterifikasi merupakan proses reaksi pembentukan ester dan gliserol dari trigliserida [13]. Dalam reaksi transesterifikasi, satu mol trigliserida akan direaksikan dengan tiga mol alkohol membentuk satu mol gliserida dan tiga mol metil ester seperti yang ditunjukkan pada Gambar 3 [14].…”

Biodiesel dapat menjadi alternatif untuk mengatasi permasalahan krisis energi dunia karena sifatnya yang renewable resources. Salah satu bahan yang dapat digunakan dalam produksi biodiesel adalah biji nyamplung. Pabrik biodiesel dari biji nyamplung ini direncanakan akan mulai beroperasi pada tahun 2026 dengan mengacu pada pemenuhan kebutuhan dalam negeri. Dengan analogi untuk memenuhi 2,94% kebutuhan biodiesel nasional sehingga kapasitas produksi pabrik biodiesel menjadi 1200.000 ton/tahun. Biodiesel dari biji nyamplung diproduksi melalui tahap proses persiapan bahan baku, esterifikasi, transesterifikasi, pemurnian biodiesel, pemurnian gliserol, dan recovery metanol. Untuk dapat mendirikan pabrik biodiesel dari biji nyamplung ini, dibutuhkan total modal investasi sebesar Rp923.438.103.243,00. Estimasi umur pabrik ini adalah 20 tahun dengan Internal Rate of Return sebesar 17,551%, Pay Out Time (POT) 4 tahun 2 bulan, dan Break Even Point (BEP) sebesar 22,4%.

“…Transesteri cation using a homogeneous catalyst is widely accepted for biodiesel production. However, it is also associated with problems like product separation, equipment corrosion, large water consumption, environmental degradation, and contamination (Topare et al, 2022). A heterogeneous catalyst can be used in place of a homogeneous catalyst to avoid as it is easy to recycle, less corrosive, safer, cheaper, and better for the environment.…”

This paper deals with the biogenic synthesis of tin oxide-corn peal ash (SnO2/CPA) nanocomposites as a novel heterogeneous catalyst for the transesterification of waste cooking oil (WCO) into biodiesel.SnO2/CPA nanocomposites were synthesized by a green method using the leaf extract of Azadirachtaindica and ash carbon obtained from the dried peels of Zea mays at room temperature. The biomolecules present in the leaf extract act as a complexing as well as a capping agent. The morphology and chemical components of the catalyst are characterized using analytical techniques such as Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDS). The highest biodiesel yield of 86.3% was attained under the optimized reaction conditions; methanol to oil ratio of 12:1, catalyst loading of 2 wt %, and reaction time of 120 min at a temperature of 60°C. 1HNMR and FTIR confirmed the presence of fatty acid methyl ester (FAME). The composition of FAME was determined using Gas Chromatography–Mass Spectrometry (GC–MS). Investigations proved that SnO2/CPA nanocomposites an effective sustainable heterogeneous green catalyst for the production of biodiesel.

“…The catalyst used can be homogeneous or heterogeneous, either acid or base. The use of homogeneous catalysts has the disadvantage of being difficult to separate, so it is necessary to re-process the separation and cause corrosion [12][13][14].…”

Biofuels are one of the renewable fuels needed to replace fossil fuels. Making biofuels requires an acid/base catalyst to speed up the reaction, one of which is esterification. This study aimed to produce sulfonated carbon from coconut shells and water hyacinth, which was carbonized at 300 °C for 6 h. It was reacted with 96 % sulfuric acid at 150 °C with variations in sulfonation times and variations in sulfonation cycles. The highest acid concentration catalyst results were obtained on water hyacinth raw materials at 1.2 mmol/g and coconut shells at 1.215 mmol/g. The more sulfonation cycles will increase the acid concentration value. The value of the catalyst activity test in the esterification reaction of the water hyacinth catalyst can convert Free Fatty Acid (FFA) better than the coconut shell catalyst. Conversion of esters in the esterification process is 75.28 % in the water hyacinth catalyst and 57.62 % in the coconut shell catalyst. The coconut shell and water hyacinth catalysts were sulfonated in the presence of Fourier Transform Infra-Red (FTIR) absorption spectra at wave numbers 1,035.77 cm–1 for the coconut catalyst and 1,033.85 cm–1 for the water hyacinth catalyst, which is a strong S=O group. The Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) analysis results indicate that the carbon sulfonate acid catalyst is amorphous. The constant kinetics of the water hyacinth catalyst reaction is 0.0139 L/mol.h, while for the coconut shell catalyst, it is 0.0045 L/mol.h. Coconut shell and water hyacinth raw materials can be used as heterogeneous acid catalysts after sulfonation. HIGHLIGHTS The problem of less and less fossil energy, so alternative energy is needed, one of which is biodiesel as a substitute for fossil energy In making biodiesel, a catalyst is needed to speed up the reaction In this study compared the carbon sulfonate catalyst derived from coconut shells and water hyacinth. Therefore, this paper should be of interest to readers in advanced materials chemistry GRAPHICAL ABSTRACT
