Biodiesel can be produced by domestic resources like straight vegetable oil, animal oil/fats, tallow and waste cooking oil. Its use, instead of the conventional diesel, contributes to the reduction of the CO 2 emissions. Production of biodiesel occurring from base catalyzed transesterification of the oil, direct acid catalyzed transesterification of the oil and/or conversion of the oil to its fatty acids and then to biodiesel. Two types of catalytic mechanisms can be used for the biodiesel production. These are the homogenous and heterogeneous catalytic processes. However, heterogeneous catalysis can be identified as solid and enzymatic. In addition solid heterogeneous catalysts can be classified as acid or base. Ηeterogeneous solid acid catalysts are of a great importance for biodiesel production. The most known catalysts of this type are zeolites, mixed oxides, sulfonic acid group catalysts, sulfonic acid modified mesoporus silica, heteropoly acids and polyoxonetalates, supported and substituted heteropoly acids and solid acids catalysts based in waste carbon. The major advantages of this type of catalysts are their reusability, their non-toxic and non-corrosive attributes as well as decrement of the biodiesel production cost.

“…Pemakaian katalis pada reaksi transesterifikasi dapat dikategorikan ke dalam beberapa kelompok, Enayati et al (2008) Penggunakan katalis padat Mg-Al Hydrocalcite dengan bahan baku canola oil menghasilkan konversi reaksi sekitar 71.9 % selama 9 jam reaksi pada temperatur 60 o C (Ilgen et al 2007). Pembuatan biodiesel dari minyak goreng bekas dengan katalis Zeolite Y menghasilkan konversi yang semakin meningkat setelah penambahan co-solvent THF dan n-Hekasana (Brito et al 2007). Konversi reaksi pada pembuatan biodiesel dari colza oil sekitar 99.89 % dengan menggunakan co-solvent THF pada suhu 60 o C dan waktu reaksi 10 menit (Caglar 2007).…”

Abstrak Asam lemak jenuh maupun tak jenuh pada minyak nabati memiliki potensi untuk diubah menjadi bahan kimia penyusun bahan bakar . Komponen asam lemak pada CPO RBD dengan komposisi terbesar adalah asam palmitat (38.2%) dan asam oleat (45.89%). Pembuatan biodiesel dalam penelitian ini menggunakan CPO (Crude Palm Oil) yang telah dimurnikan melalui reaksi transesterfikasi dengan pereaksi etanol dan katalisator KOH. Penambahan urea sebagai zat aditif pada reaksi dapat meningkatkan kualitas biodiesel yang diperoleh serta lebih efisien dalam tahapan pemurnian. Persentase kadar FAME (Fatty Acid Metyl Ester) setara dengan persen yield biodiesel pada proses reaksi tanpa penambahan urea adalah 90.34% dan mengalami peningkatan setelah penambahan urea sebesar 98%. Densitas yang dihasilkan pada reaksi tanpa zat aditif 0.868 gr/ ml dan reaksi dengan penambahan zat aditif memiliki densitas 0.866 gr/ml, kedua produk tersebut telah sesuai dengan standar SNI yakni berkisar 0.85–0.89. Kata kunci : biodiesel, CPO, zat aditif Abstract Saturated and unsaturated fatty acids in vegetable oils have potential to be converted into constituent of chemicals fuel. Fatty acids in the RBD palm oil with the largest composition are palmitic acid (38.2%) and oleic acid (45.89%). Production of fuel which substitute diesel fuel (biodiesel) from CPO (Crude Palm Oil) which has been purified by transesterification reaction with ethanol reagent and KOH catalyst. The addition of urea as an additive substancein the reaction to improve the quality as well as more efficient biodiesel obtained in the purification stages. Percentage value of FAME(Fatty Acid Metyl Ester)or yield biodiesel in the reaction without the addition of urea is 90.34% and after the addition of urea increased by 98%. Density of product that produced in the reaction without additives is 0.868 g / ml and for reaction with additives has a density of 0.866 g / ml, both of these products are met the criteria of SNI standards which ranged from 0.85 to 0.89.

“…This limits its use as a catalyst for transesterification. Brito et al [1] studied fried oil transesterification reactions with methanol using several zeolites Y and interchanged with CaCl2 and KOH. It was observed that best yield of 98 % fatty acid methyl ester (FAME) was obtained with Y756 zeolite interchanged with KOH.…”

Transesterification of Algae Oil using K2CO3/ZnO Heterogeneous Base Catalyst

The objective of the present work was to develop a heterogeneous base catalyst K2CO3/ZnO for transesterification of algae oil. This catalyst was prepared by wet impregnation method calcinated at high temperature of 600 °C. The catalyst was characterized by X-ray diffraction technique. The crude algae oil was degummed and its free fatty acid was reduced to 2 % by methanol treatment. Methanol was used to convert triglycerides to biodiesel using K2CO3/ZnO. The doping of 30 % K2CO3 on ZnO calcined at 600 °C was studied on biodiesel yield. The reaction parameters such as temperature, stirring rate, amount of catalyst, methanol to oil molar ratio on the yield of fatty acid methyl ester were investigated. Highest yield was obtained for 7 % catalyst, 9:1 methanol to molar ratio at 80 °C for 30 % K2CO3/ZnO. This study proved that the catalyst loading less than 5 % was unsuccessful in biodiesel yield. The physio-chemical properties of the produced algae biodiesel was determined as per ASTM test procedures.
