Abstract

Pd/C-catalized deoxygenation of Oleic Acid as a vegetable oil model for renewable diesel fuel synthesis.Second-generation biofuels called renewable diesel that are drop-in replacements for traditional petroleum derived transportation fuels (diesel, gasoline, and jet fuel) can be produced from triglycerides by thermocatalytic processes. One of the alternatives of renewable solar synthesis is through deoxygenation reaction using heterogeneous catalysts. In this experiment, oleic acid was used as model compounds to study the catalytic deoxygenation process of triglycerides to hydrocarbons like diesel (renewable diesel). The 1% Pd/C catalyst used in the study was prepared by microwave polyol process.  At 400 oC and under H2 pressure of 9 bar and 15 bar, The Pd/C catalysts tended to be more selective toward decarboxylation pathway. Under H2, the main liquid-phase product was alkanes and aromatic, while the main gaseous products were CO and CO2. The conversion was around of 75% with selectivity of renewable diesel was 50.14%. Measured physical properties of renewable diesel (density and viscosity) is comparable to those specified for commercial diesel.Keywords: deoxygenation, oleic acid, Pd/C catalys, microwave polyol process, renewable dieselAbstrakGenerasi ke-2 dari bahan bakar nabati yang disebut dengan solar terbarukan dapat menggantikan bahan bakar turunan dari minyak bumi untuk transportasi (solar, bensin dan bahan bakar pesawat) dengan cara diproduksi dari trigliserida melalui reaksi termokatalitik. Salah satu rute sintesis solar terbarukan adalah melalui proses reaksi deoksigenasi berkatalis heterogen. Di dalam penelitian ini, asam oleat digunakan sebagai senyawa model untuk mempelajari deoksigenasi katalitik dari trigliserida menjadi hidrokarbon seperti solar (solar terbarukan). Katalis Pd/C yang digunakan dalam studi ini dipersiapkan dengan metode microwave polyol process. Pada kondisi operasi suhu 400 oC dan tekanan H2 sebesar 9 bar dan 15 bar, katalis 1 %-berat Pd/C lebih cenderung mengarahkan reaksi ke jalur dekarbokasilasi. Pada kondisi tekanan H2 didapatkan produk cair yang utama adalah alkana dan aromatik sedangkan produk gasnya adalah CO dan CO2. Konversi reaksi yang dihasilkan adalah sekitar 75% dengan  selektifitas produk solar terbarukan adalah 50,14%. Sifat fisik (densitas dan viskositas) solar terbarukan mendekati sifat fisik solar komersial.Kata kunci: deoksigenasi, asam oleat, katalis Pd/C, microwave polyol process, solar terbarukan

Abstract

Due to economical, social and ecological reason, several studies have been done in order to obtain alternative fuel sources. In this respect, fermentation, trans-esterification and pyrolysis if biomass have been proposed as alternative solutions. Among these different approaches, pyrolysis seems to be a simple and efficient method fuel production. Pyrolysis, assisted by solid catalysts, has also been reported and it was recognized that the product selectivity is strongly affected by the presence and the nature of heterogeneous catalysts. The catalytic pyrolysis of straight Jathropha curcas oil (SJO) over nanocrystalline NiO/Al2O33 at 475 OC was studied. NiO/Al2O3 catalyst was used in pyrolysis for purpose of selectively cracking of triglyceride. Nanocrystalline NiO/Al2O3 was prepared by simple heating method with polymer solution as growth inhibitor. The liquid product (bio-oil) were analyzed by GC-FID and FTIR, showing the formation of carboxylic acids, paraffin, olefins, and ketones. Measured physical properties of bio-oil is comparable to those specified for diesel oil. Keywords: SJO, nanocrystalline, simple heating method, catalytic pyrolysis, bio-oilAbstrakAdanya pertimbangan keekonomian, sosial, dan ekologi, menyebabkan dilakukannya penelitian guna mendapatkan sumber bahan bakar alternatif. Berkaitan dengan hal tersebut, maka reaksi-reaksi seperti permentasi, transesterifikasi dan pirolisis dari biomasa telah digunakan sebagai alternatif solusi. Diantara pendekatan-pendekatan yang berbeda tersebut, pirolisis merupakan metode yang sederhana dan efesien untuk menghasilkan bahan bakar. Pirolisis, yang dibantu dengan katalis padat, telah juga dilaporkan dan diketahui bahwa selektifitas produknya sangat dipengaruhi oleh kehadiran dan sifat dari katalis-katalis heterogen yang digunakan. Pirolisis berkatalis dari minyak jarak pagar (straight Jathropha curcas oil, SJO) melalui nanokristal NiO/Al2O3 pada suhu 475 OC telah dilakukan percobaanya. Katalis NiO/Al2O3 digunakan dalam pirolisis dengan tujuan untuk perengkahan selektif dari trigliserida. Nanokristal NiO/Al2O3 dibuat dengan menggunakan metode simple heating dengan pelarut polimer sebagai penghambat pertumbuhan. Produk cair yang dihasilkan (bio-oil) telah dianalisa dengan menggunakan GC-FID dan FTIR, memperlihatkan adanyanya gugus asam-asam karboksilat, parafin, olefin dan keton. Sifat fisik yang diukur dari biooil dapat diperbandingkan kesetaraanya dengan spesifikasi dari minyak solar.Kata kunci: SJO, nanokristal, metode simple heating, pirolisis berkatalis, bio-oil

Abstract

Biofuels have great potential to fulfill the energy needs of Indonesia. The process used is hydrodeoxygenation reaction (HDO) whose products are known as renewable diesel. This study focuses on preparation NiMo/Zeolite catalyst for synthesizing renewable diesel from jatropha oil. Preparation of NiMo/Zeolite catalyst is done by using microwave polyol process method. Microwave polyol method is a modification from incipient wetness method to overcome energy consumption and preparation time problem. Microwave polyol method is done by using a fast and uniform electric radiation from microwave as heating medium to dry catalyst. The catalyst result by using microwave polyol method gives the surface area of ​​5.45m2/g and has average crystal size of 62.98nm. NiMo/Zeolit catalyst used to synthesize renewable diesel at 375oC, pressure 12 bar, catalyst loading 1% mass of Jathropa Oil and stirer speed 800 rpm.

Abstract

The Petroleum diesel-based fossil fuel remains the primary source of energy consumption in Indonesia. The utilization of this unrenewable fuel depletes fossil fuels; thus, an alternative, renewable fuel, such as one based on biohydrocarbon from biomass-green diesel-could be an option. In this work, green diesel was produced through the hydrodeoxygenation from palm oil and processed in a batch-stirred autoclave reactor over natural zeolite (NZ) and NZ modified with 3 wt.% Fe metal (Fe/NZ) as heterogeneous catalyst. NZ showed high crystallinity and suitability to the simulated pattern of the mordenite and clinoptilolite phases according to X-ray diffraction (XRD) analysis. The presence of Fe metal was further confirmed by XRD, with an additional small diffraction peak of Fe0 that appeared at 2θ = 44-45°. Meanwhile, NZ and Fe/NZ were also characterized by Scanning electron microscopy (SEM) with Energy Dispersive X-ray (EDX), X-ray Fluorescence (XRF), and Surface Area Analyzer (SAA). The obtained materials were tested for the conversion of palm oil into diesel-range hydrocarbons (C15-C18) under conditions of 375 °C and 12 bar H2 for 2 h. NZ and Fe/NZ produced a liquid hydrocarbon with straight-chain (C15-C18) alkanes as the most abundant products. Based on Gas Chromatography-Mass Spectrometry (GC-MS) measurement, a higher conversion of palm oil into diesel-like hydrocarbons reached more than 58% and 89%, when NZ and Fe modified NZ (Fe/NZ), respectively were used as catalysts.
