Abstract

The usual problem encountered on a reversible reaction is that the reaction cannot achieve a complete conversion of reactants since it is limited by the thermodynamic equilibrium. Due to this low conversion, it will face challenges with product purification and recycling of the reactants, which then cause an increase in the operation cost. To obtain higher conversion, it is necessary to shift the equilibrium towards the products by continuously removing the water formed. One popular example of reversible reaction is esterification process. In this research, water removal was conducted through an adsorption process using zeolite 4A. Effect of zeolite 4A on water concentration in the liquid phase esterification of acetic acid and 1-butanol catalyzed by sulfuric acid was investigated. It was performed in an isothermal batch reactor. The molar ratio of 1-butanol - acetic acid was 1.4 times theoretically, the catalyst concentration was 1 % wt and the mixing intensity was 1000 rpm. The influence of the temperature was studied at 40 to 80 °C and the zeolite 4A loading was varied at 1.6 to 5.52 % w/ v. The reaction was compared to the conventional esterification reaction carried out under identical conditions but without addition of zeolite 4A. Concentration of each component in the system was analyzed using on-line Gas Chromatography. Effect of removing the water produced during the reaction by using zeolite 4A was demonstrated. It was revealed that the amount of water removed was proportional to the amount of the zeolite 4A to be employed. On the other hand, the increase of the temperature led to the lower amount of water to be adsorbed. Among all the experiments, the best result was achieved on the addition of 5.52 % b/v zeolite 4A at 40 °C, where water concentration was 3.1356 g mole/L and the conversion was 76.11 % at the equilibrium condition. As comparison, water concentration on the conventional reaction performed at 40 °C was 6.9161 g mole/L and the conversion was 62.5 % at the equilibrium condition. The equation illustrating the effect of zeolite 4A loading on the conversion obtained at the equilibrium condition was: XAe = 0.6248 + 0.0868 C4A0.2848, where XAe was equilibrium conversion of Acetic Acid and C4A was Zeolite 4A loading (g/100 mL liquid).

Abstract

Pelarut atau solvent merupakan salah satu komponen penting dalam proses kimia pada industri kimia. Salah satu jenis pelarut yang sering digunakan pada industri cat dan pelapis yaitu pelarut berbasis hidrokarbon yang terdiri dari campuran cairan kompleks yang beragam dan mengandung unsur alifatik, alisiklik dan aromatik (C5-C8). Aromatik hidrokarbon merupakan polutan lingkungan yang terkenal bersifat toksik, karsinogenik dan mutagenik sehingga dibutuhkan pelarut berbasis hidrokarbon dengan kandungan aromatik dibawah 1%. Metode pemisahan yang tepat untuk memisahkan komponen aromatik dan nonaromatik yang memiliki titik didih berdekatan adalah distilasi ekstraktif dengan entrainer sulfolana. Pada penelitian ini, sistem distilasi dengan entrainer sulfolana dijalankan menggunakan process simulation software Aspen Plus V.10 dengan tujuan untuk mengetahui pengaruh jumlah sulfolana, feed stage dan jumlah stage terhadap sifat fisis pelarut berbasis hidrokarbon serta analisis energi dan ekonominya. Simulasi ini difokuskan pada variasi rasio sulfolana:crude feed ( 7:1, 7,5:1, 8:1, 8,5:1), variasi feed stage (stage ke-10 sampai ke-35) dan variasi jumlah stage (70,75,80). Hasil penelitian didapatkan kondisi optimum yaitu menggunakan rasio sulfolana:crude feed  8,5:1, feed stage ke-25 dan jumlah stage 80.

Abstract

Indonesia sebagai negara agraris, sebagian penduduk Indonesia bermata pencaharian di bidang pertanian. Pada umumnya, masyarakat menggunakan pestisida untuk membasmi hama. Karena tingginya penggunaan pestisida maka WHO (2016) menyatakan kasus keracunan pestisida mencapai 193.000 jiwa selama tahun 2012. Untuk mengatasi permasalahan tersebut, biopestisida menjadi bahan alternatif pengganti pestisida karena lebih aman dan ramah lingkungan. Salah satu bahan alam yang berpotensi sebagai biopestisida adalah kulit durian. Rata- rata produksi durian setiap tahunnya 780.032,8 ton/tahun. Limbah kulit durian memiliki berat 60-75% dengan kandungan senyawa metabolit sekunder relatif tinggi belum termanfaatkan secara maksimal. Senyawa tersebut dimanfaatkan sebagai antioksidan dan antimikroba dalam proses pembasmi hama. Biopestisida yang dikembangkan dengan metode sokletasi menghasilkan ekstrak berbentuk cair. Namun, hasil tersebut kurang efektif dan mudah teroksidasi sehingga menurunkan keefektifitasan kadar bahan aktif. Mengatasi masalah tersebut maka perlu dikembangkan inovasi dengan proses enkapsulasi. Artikel ini me-review pengembangan metode enkapsulasi. Metode yang dapat digunakan untuk enkapsulasi biopestisida yaitu ekstrusi, spray chilling dan spray drying. Metode spray drying lebih berpotensi mengenkapsulasi biopestisida dari kulit durian karena memiliki efisiensi enkapsulan lebih tinggi dan hampir mendekati 100%. Distribusi ukuran partikel yang dihasilkan tergolong nanoenkapsulan. Indonesia as an agrarian country, most of Indonesia's people work in agriculture. In general, people use pesticides to eradicate pests. Due to the high use of pesticides, WHO (2016) stated the case of pesticide poisoning reach 193,000 in 2012. To solve the problem, Biopesticide as an alternative of synthetic pesticides because it’s more safe and environmentally friendly. One of the natural ingredients that potentially as biopesticide is durian peel. The average durian production per year is 780,032.8 tons/year. Durian peels waste weighs 60-75% with a relatively high contains of secondary metabolite not yet fully utilized. It’s used as antioxidants and antimicrobials in pesticides. Biopesticide is developed by socletation method. However, the results are less effective because it’s easily oxidized, so reduce the flavonoid efectiveness. To solve this problem, to be developed innovation with encapsulation process. This article reviews the development of encapsulation methods. Methods that can be used for biopesticide encapsulation are extrusion, spray chilling and spray drying. Spray drying method is more likely to encapsulate biopesticides because it has higher encapsulation efficiency and is close to 100%. The resulting particle size distribution is classified as nanocapsul.

Abstract

In the present study, biodiesel was produced via the enzymatic interesterification of Crude Palm Oil (CPO) and methyl acetate within ultrasonic condition. In contrast to alcohol, methyl acetate as an acyl acceptor does not inhibit lipase activity and can create triacetin as a useful byproduct.  In this work, Immobilized lipase from Candida Antartica A (CaLA) was utilized as biocatalyst and the effect of using non-pretreated CPO and pre-treated CPO as feedstock were explored. The pre-treatment of CPO involves degumming with acid, washing with water, and bleaching. The enzymatic interesterification was conducted in three-neck flasks using an ultrasonic water bath at 45o C.  Few parameter effects on biodiesel production were also investigated, including the effect of molar ratio of CPO to methyl acetate, the effect amount of lipase, and the reusability of immobilized lipase (CaLA) in the interesterification reaction.  The highest average Biodiesel yield of 80.6% was obtained from pretreated CPO at a molar ratio of 1:9 with 100 mg (1% w/v) of Immobilized CaLA, after three hours of reaction. Further research on the reusability of immobilized CaLA revealed that the yield of biodiesel reduced significantly after the second run. The results of the present study also demonstrated that Immobilized CaLA performed well at low concentrations but had low stability, with productivity decreasing to 92% upon reuse after the initial run. In order to make Immobilized lipase economically viable, further research must be conducted to overcome its low stability in the reaction.

Abstract

Biodiesel is one of the promising energy source alternatives to fossil fuel. To produce biodiesel in a more economical way, the employment of the low-cost feed stocks, such as non-edible oils with high free fatty acid (FFA), is necessary. Accordingly, the esterification reaction of FFA in vegetable oils plays an important role in the biodiesel production. In this work, esterification of FFA contained in Crude Jatropha Oil (CJO) in the presence of tin (II) chloride catalyst in a batch reactor has been carried out. The esterification reaction was conducted using methanol at the temperature of 40-60 °C for 4 hours. The effect of molar ratio of methanol to oil was studied in the range 15:1 to 120:1. The influence of catalyst loading was investigated in the range of 2.5 to 15% w/w oil. The optimum reaction conversion was obtained at 60 °C with the catalyst loading of 10% w/w oil and molar ratio of methanol to oil of 120:1. A pseudo-homogeneous reversible second order kinetic model for describing the esterification of FFA contained in CJO with methanol over tin (II) chloride catalyst was developed based on the experimental data. The kinetic model can fit the data very well.
