Abstract

ABSTRACTIndonesia has an abundant quantity of natural zeolites that have not yet been utilized maximally. On the other hand, fishpond farmers have a problem regarding the presence of ammonium in the fishpond water which will negatively impact to survival of fish, especially small fish. To solve this problem, this research was utilizing natural zeolite to degrade ammonium in the fishpond water. This research aimed to test mordenite natural zeolite from Bayah as an adsorbent to collaborate some variables impact to reach more maximal adsorption. The variables that were used to be observed were: mordenite natural zeolite from Bayah as an adsorbent which has been activated by 1-7 N H2SO4 and the other was without activation, ammonium concentration of 80-800 ppm, the particle size of adsorbent of 80 and 150 mesh, stirring speed of 600 and 800 rpm, and without stirring by duration adsorption time of 60 minutes. The research results showed that mordenite natural zeolite after activated was able to adsorb of 100% ammonium, while for the mordenite natural zeolite from Bayah without stirring was of 80%, by the same absorption time. These results will give significant benefits for fishpond farmers to increase their productivity because of the increase in fish survival.Keywords: adsorption, adsorbent, zeolite, amoniumABSTRAKKandungan zeolit alam di Indonesia cukup melimpah dan belum termanfaatkan secara maksimal.

Abstract

Currently, the fuel oil for transportation and industry is produced mostly from fossil fuels. Because fossil fuels are a limited resource, biomass could be an alternative resource. Empty fruit bunch (EFB) is biomass waste from fresh fruit bunch processing in palm oil mills. EFB can be converted to bio-crude oil through pyrolysis at temperatures from 400 to 600 °C. The quality of bio-crude oil must be upgraded due to its high oxygen content. Esterification of bio-crude oil potentially improves the quality of bio-crude oil by using zeolite as catalyst. The purpose of this research was to investigate the properties of Bayah natural zeolites for upgrading the quality of bio-crude oil from EFB pyrolysis. Bayah natural zeolite was activated using various NaOH concentrations. Characterization of the natural zeolites was performed by using X-ray diffraction (XRD), scanning electron microscope-energy dispersive X-ray (SEM-EDX), and nitrogen physisorption. The optimum ratio of Si/Al of the modified Bayah natural zeolites was 3.91. The surface area of the parent was initially 19 m2/g and increased significantly to 150 m2/g after treatment with 0.4 M NaOH solution. The application of the activated zeolites for bio-crude oil esterification successfully decreased the total acid number.

Abstract

Coal tar is a high viscosity liquid and has a black color which formed as a by-product of the production process of coke and gas from coal. Coal tar compounds have high economic value because they can be resold and valuable. One valuable compound is naphthalene. The coal tar evaluation process of its constituent components is carried out by distillation, with a high level of naphthalene purity achieved up to 96%. The coal tar distillation process normally requires high energy, which leads to expensive operational costs.  In order to achieve low energy consumption during the distillation process,  a study of energy analysis in the coal tar distillation process needs to be done. This study aims to analyze the energy consumption of the distillation process by using simulator software. Process simulations will be performed using the Aspen HYSYS simulator, where the variable in the form of the ratio of the feed flow rate into the distillation tower is divided into two streams, namely cold stream and hot stream. The location of the changed input feed is also a changing variable in this study. The fixed variables in this study were the operating conditions of the distillation process and the incoming feed flow rate, which was 2 m3/hour. The simulations suggest that the amount of energy saved in the condenser unit is 4.40 percent and 5.28 percent in the reboiler unit. Tar batubara adalah cairan dengan viskositas tinggi dan berwarna hitam, hasil samping dari proses produksi kokas dan gas dari batubara. Senyawa tar ini memiliki nilai ekonomi yang tinggi karena komponen-komponen penyusunannya dapat dijual kembali dan bernilai, salah satunya adalah naftalena. Proses pemisahan tar batubara dari komponen-komponen penyusunnya dilakukan dengan cara destilasi, dengan tingkat kemurnian naftalena yang tinggi yaitu 96%. Proses destilasi tar batubara ini seringkali membutuhkan energi yang besar, sehingga kajian mengenai analisa konsumsi energi pada proses destilasi tar batubara perlu dilakukan. Studi analisa energi pada proses destilasi tar batubara dilakukan dengan menggunakan metode simulasi proses. Simulasi proses destilasi dilakukan dengan menggunakan perangkat lunak berupa Aspen HYSYS, dimana variabel yang berupa ratio laju alir umpan masuk ke dalam menara destilasi dibagi menjadi 2 aliran, yaitu aliran dingin dan aliran panas. Letak umpan masuk yag dirubah juga merupakan variabel berubah pada penelitian ini. Variable tetap pada penelitian ini adalah kondisi operasi proses destilasi dan laju alir umpan masuk, yaitu 2 m3/jam. Hasil dari simulasi yang telah dilakukan didapatkan besarnya energi yang dapat dihemat sebesar 4.40% pada unit condenser dan 5.28% pada unit reboiler.

Abstract

Operasi sedimentasi merupakan salah satu tahapan kunci dari keseluruhan proses produksi pati ubi jalar. Kajian untuk mempelajari karakteristik sedimentasi telah dilakukan dengan variabel utama berupa konsentrasi pati ubi jalar. Konsentrasi pati ubi jalar yang diamati dalam penelitian ini berada dalam interval 1% - 21% b/v dengan rentang 2%. Hasil penelitian menunjukkan bahwa terdapat tiga rejim berbeda yang berhasil diidentifikasi dalam peristiwa sedimentasi berdasarkan rentang konsentrasi suspensi, yaitu rejim konsentrasi rendah yang berada pada konsentrasi di bawah 17% b/v, rejim konsentrasi transisi yang terletak dalam rentang konsentrasi 17% - 21% b/v, dan konsentrasi tinggi yang berada pada konsentrasi di atas 21% b/v. Pada penelitian ini juga dihasilkan persamaan empiris y = k1/t) yang menerangkan hubungan antara ketebalan endapan dan waktu untuk pola pengendapan konsentrasi rendah. Parameter k1, k2, dan k3–k2exp(-k3yang diperoleh bergantung pada konsentrasi suspensi. Persamaan empiris yang dirumuskan memberikan kesesuaian yang cukup baik terhadap data-data percobaan (r2> 0,98).

Abstract

Makalah ini mengkaji tentang pemodelan dan simulasi oksidasi katalitik metana menggunakan reverse flow reactor (RFR). Pokok bahasan tertuju pada pengembangan prosedur pengambilan panas dalam periode start-up untuk umpan dengan konsentrasi tetap, yaitu 1%-v metana dan umpan dengan konsentrasi berfluktuasi, yaitu pada rentang 0,1-1%-v metana, yang mengikuti fungsi gelombang persegi. Hasil simulasi menunjukkan pengambilan panas dapat dilakukan selama start-up baik untuk konsentrasi tetap maupun konsentrasi berfluktuasi tanpa menyebabkan RFR padam. Pengambilan panas pada switching time (ST) yang cepat memberikan beberapa keuntungan dibandingkan pada ST  yang lama, yaitu lebih banyak panas yang dapat diekstrak dan lebih besar penurunan temperaturnya, sehingga aman bagi katalis dan reaktor.

Abstract

Natural zeolite in Indonesia generally divided into 2 types, which are mordernite and clinoptilolite. As far the use of zeolites is very limited. This experiment tries to use both types of natural zeolites to find out its work. The purpose of this experiment is testing the performance of mordenite natural zeolite from Bayah-Indonesia and clinoptilolite from Lampung- Indonesia in the esterification reaction between glycerol and oleic acid integrated by several variable that affect the reaction. The experiment will be done by using three-neck rounded flask batch reactor. The result showed that modernite zeolite has a better performance compared to clinoptilolite zeolite. To get the oleic acid conversion of 70%, clinoptilolite zeolite needs 4% catalyst of glycerol weight and reactant ratio of 6:1 mole of glycerol/mole of oleic acid, Meanwhile the mordernite zeolite only needs 2% catalyst of glycerol weight with reactant ratio of 4:1 mole of glycerol/mole of oleic acid.Keywords: natural zeolite; glycerol; reaction; diffusion
