Abstract

Tandan Kosong Kelapa Sawit (TKKS) merupakan limbah padat dengan volume yang cukup besar dari produksi kelapa sawit. Dari total 24,25% TKKS yang dihasilkan, saat ini pemanfaatan limbahnya masih jauh dari potensinya sekitar 95,45 ton/ tahun yang dihasilkan tidak dimanfaatkan dengan baik. Tandan kosong kelapa sawit dapat dikonversi menjadi abu yang siap dipakai untuk proses produksi biodisel melalui reaksi transesterifikasi. Hasil Uji karakteristik menunjukkan bahwa abu TKKS dapat menjadi katalis yang potensial karena menunjukkan kadar kalium mencapai 48,25% . Partikel katalis memiliki cross section area 16.2 A2/mol dengan luas permukaan 0,012 m2/g dan total volume pori katalis 0,007674 cc/g. Dalam kajian ini juga dilakukan proyeksi ketersediaan TKKS dari perkebunan sawit dan dikorelasikan dengan proyeksi kebutuhan katalis untuk industri biodiesel. Setiap tahun diperkirakan sedikitnya terdapat 15,5 juta ton TKKS yang dapat dikonversi menjadi abu sawit melalui proses torefaksi dan sejenisnya. Kebijakan penggunaan biodisel B35 di tahun 2023 diperkirakan akan meningkatkan volume produksi biodisel sampai 13,5 juta kL. Dengan demikian diperkirakan kebutuhan katalis komersial mencapai 120-140 ribu ton per tahun. Melalui neraca massa TKKS menjadi katalis abu TKKS, dimungkinkan tersedia 2,33 juta ton abu TKKS untuk dimanfaatkan sebagai katalis produksi biodiesel. Neraca massa konversi TKKS menjadi abu menunjukkan bahwa 15%-b abu yang siap dipakai menjadi katalis dapat dihasilkan dari setiap ton TKKS.

Abstract

Biodiesel production using novel glycerol and potassium carbonate-based catalysts has not been developed under the Taguchi technique. This study aims to determine the most influential parameter in biodiesel production from refined bleach-deodorized palm oil (RBDPO) using DES K2CO3-Glycerol as the novel catalyst. The raw material was subjected to transesterification at the desired reaction parameters estimated by the orthogonal 16-run (L16) approach with 2 levels and 4 factors of the Taguchi technique. Signal-to-noise ratio (SNR) and ANOVA were used to confirm the predicted value. From the results, the catalyst is the most influential variable in the TG value of biodiesel, placed in the first rank of the influence factor. Biodiesel production with a minimum total glycerol value (0.210%) using DES K2CO3-Glycerol as a catalyst is most optimally produced at 95 °C for 4 h and 400 rpm using 30 wt% methanol and 4 wt% catalysts achieved by the Taguchi technique. The biodiesel obtained from RBDPO complies with the required international standards. Doi: 10.28991/ESJ-2023-07-03-018 Full Text: PDF

Abstract

Biodiesel production is generally catalyzed by potassium methylate or sodium methylate catalysts based on KOH and NaOH and these catalysts are still imported. The search for a cheap and effective catalyst continues to be carried out by researchers. One of the catalyst support materials currently in use involves impregnating K2CO3 with various substances, resulting in a heterogeneous catalyst. In this study, it was tried to use K2CO3 dissolved in methanol to produce a homogeneous potassium methylate catalyst. Potassium methylate-based homogeneous catalyst K2CO3-methanol is proven to have a very high function in the transesterification reaction of Refined Bleached Deodorized Palm Oil (RBDPO) into biodiesel, this is evidenced by the use of a catalyst percentage of 2% w and 30% w methanol to the weight of RBDPO resulting in an acid content in biodiesel of only 0.12% and a total glycerol of 0.124% in reaction time 3 hours, with the purity of the methyl ester in biodiesel reaching 98.80%. Meanwhile, for the calculation of homogeneous reaction kinetics, a reaction rate equation is produced where the order of the RBDPO transesterification reaction is order 2 (two) and the reaction rate constant is 0.0044.

Abstract

PT Bukit Asam Tbk has adopted the use of plant-based diesel oil in compliance with the rules established by the Minister of Energy and Mineral Resources No. 12 of 2015 from previously using fossil diesel. One of the decarbonization program's initiatives to reduce emissions is to replace the use of fossil fuels with biodiesel for all production equipment. To obtain results on the decrease or increase in the environmental quality of the use of fossil fuels and biodiesel, this research requires comparative data obtained from the results of ambient air quality, emissions, and opacity test. Based on research data in the years 2018 – 2022, the emission quality test was obtained with an average CO parameter of 550.83 mg/nm3, which exceeded the quality standard of 540 mg/nm3, SO2 parameter of 79.03 mg/nm3 from the quality standard of 900 mg/nm3. The NO2 parameter is 161.29b mg/nm3 from the quality standard of 1200 mg/nm3, with the quality standard parameters referring to thw Minister of Environment and Forestry Regulation No. 15 of 2019. Based on quantitative analysis approaches method and trend analysis obtained the emission results experienced an increase with trend line analysis but were still below the quality standards. The results at IUP Banko Barat for mobile equipment sources were obtained at 5.23% HSU, while for static equipment sources, they were obtained at 9.88% HSU from the quality standard of 40% based on South Sumatera Governor Regulation No. 06 of 2016. It can be concluded that the variance of fuel use for the 2018-2022 period has no significant effect on the air quality test emissions and opacity results because it is still below the quality standard.

Abstract

This study investigates the synthesis and performance of a K2CO3 catalyst derived from oil palm empty fruit bunch (EFB) ash for sustainable biodiesel production. X-ray Diffraction (XRD) revealed a dominant K2CO3 crystalline phase, while X-ray Fluorescence (XRF) confirmed a high potassium content (>40%). Despite its low surface area (0.11 m2/g), the catalyst demonstrated high transesterification activity, achieving an optimal biodiesel yield of 85.89% with 3 grams of catalyst. Its high thermal stability, strong base sites, and macroporous structure all contributed to enhanced catalytic efficiency. Sustainability and techno-economic assessments indicate the catalyst’s potential to reduce production costs, utilize biomass waste, and lower greenhouse gas emissions. Thus, the EFB ash-based K2CO3 catalyst shows significant promise for supporting environmentally friendly biodiesel production and contributing to the transition to a green economy and renewable energy.
