Kurniawati, FitrianaDewi (2016) Reaksi Kondensasi Furfural dengan Aseton dan Reaksi Hidrodeoksigenasinya (HDO) Menggunakan Katalis Ni/ZrO2. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mengetahui aktivitas katalis Ni/ZrO2 terhadap reaksi hidrodeoksigenasi senyawa hasil reaksi kondensasi furfural dan aseton menggunakan metode autoclave oil batch reactor. Katalis Ni/ZrO2 dibuat melalui metode impregnasi basah dengan mencampurkan Ni(NO3)2.6H2Odan ZrOCl2.8H2O yang dilarutkan dalam air dan ditambahkan larutan amoniak secara perlahan hingga suasana basa (pH 8). Temperatur yang digunakan untuk kalsinasi dan reduksi katalis adalah 500oC. Karakterisasi katalis dilakukan dengan metode difraksi sinar-X (DSX) dan fluorosensi sinar-X (FSX). Uji aktivitas katalis dilakukan pada reaksi hidrodeoksigenasi (HDO) produk kondensasi menggunakan pelarut air dan asam asetat (19:1). Reaksi HDO dilakukan menggunakan metode autoclave oil batch reactor pada atmosfer H2. Produk HDO pada temperatur 200oC dikarakterisasi menggunakan spektrofotometer FTIR dan Kromatografi Gas-Spektrometer Massa (KG-SM). Hasil karakterisasi spektrofotometer FTIR menunjukkan adanya peningkatan intensitas gugus karbonil (C=O) keton pada bilangan gelombang 1712,67 cm-1. Karakterisasi Kromatografi Gas- Spektrometer Massa (KG-SM) menunjukkan terbentuknya produk baru yaitu, 1,5-di(furan-2-il)-4-hidroksipenta-1-ena-3-on, Tridekana- 1,7,13-triol dan 1-undekena-6-on. Berdasarkan hasil senyawa yang diperoleh menunjukkan bahwa katalis Ni/ZrO2 dapat digunakan dalam reaksi hidrodeoksigenasi.
English Abstract
This research is investigated the catalytic activityof Ni/ZrO2 catalysts applied for hydrodeoxygenation reaction of compound condensation reaction of furfural and acetone using oil batch reactor autoclave method. Ni/ZrO2 catalyst were prepared by wet impregnation method by mixed Ni(NO3)2.6H2O and ZrOCl2.8H2O were dissolved in water and the solution of ammonia was dropped gradually into the solution until base condition (pH 8). Temperature used for calcination and reduction catalyst is 500 ° C. The catalyst was characterized by X-ray diffraction (XRD) and X-rays fluorescence (XRF). The catalyst performance was tested for hydrodeoxygenation (HDO) reaction of condensation product using water and acetat acid (19:1) as solvent. HDO reaction was conducted by autoclave oil batch reactor method in H2 atmosphere. HDO product at 200 oC characterized by FTIR spectrophotometer and Gas Chromatography-Mass Spectrometer (GC-MS). The characterization of Fourier Transformed IR showed the increasing of carbonyl (C=O) ketones character at 1712,67 cm-1. The characterization of Gas Chromatography-Mass Spectrometer (GC-MS) showed the formation of 1,5-di (furan-2-yl) -4-hydroxyipent-1-ene-3-one, tridecane-1,7,13- triol and 1-undecene-6-one. Based on the result showed that Ni/ZrO2 catalyst can be used for hydrodeoxygenation reaction.
