Synthesis and Characterization of Ni/Hydrotalcite and Its Application in Hydrocracking Calophyllum Inophyllum Oil

Abstract

This research aims to synthesize hydrotalcite as an alternatives of catalyst support of hydrocracking of vegetable oils. Hydrotalcite can be synthesized in several ways, the most common is coprecipitation method. Hydrotalcite was synthesized using Mg/Al mole ratio of 1: 1, NaOH and Na 2 CO 3 as base solutions. Ni/hydrotalcite catalyst was synthesized by incipicient wetness impregnation method with Ni impregnation of 10% w/w. The characterization of the crystal structure was determined by X-ray diffraction (XRD). The spesific surface area (S BET ) was determined by adsorption-desorption of nitrogen, it were obtained 201 m 2/ g after impregnation and 191 m 2 /g before impregntion. The test of performance of catalyst was conducted by hydrocracking reaction of Calophyllum inophyllum oil. The liquid products were analyzed by gas chromatography mass spectrometry (GC-MS). Hydrocracking process produced gasoline, kerosene, gas oil with yield of 0.36%, 2.45%, 54.88% respectively, conversion of 96.26% and selectivity of gas oil of 84.39%.

Effect of Calcination at Synthesis of Mg-Al Hydrotalcite Using co-Precipitation Method

“…Application of Mg-Al hydrotalcite is support catalyst which had basicity and large specific surface area that suitable for transesterification reaction. In previous research [18], Mg-Al hydrotalcite with Mg/Al molar ratio 1:1 as a supported catalyst had increasing acidity so that suitable for hydrocracking reaction.…”

Co-Ni/HZSM-5 Catalyst for Hydrocracking of Sunan Candlenut Oil (Reutealis trisperma (Blanco) Airy Shaw) for Production of Biofuel

“…The oxygenated compounds containing carboxylic acid of 4.16 area% were found [5]. Marlinda et al reported that n-C 15 and n-C 17 were the main abundant hydrocarbon compounds in biofuel produced through hydrocracking on Cerbera manghas oil at temperature of 350 o C and pressure of 15 bar for 2 h with Co(0.88)-Ni(3.92)/HZSM-5 catalyst.…”

“…Estes minerais podem ocorrer em ambientes como depósitos salinos, o que comprova que altas temperaturas e pressões não são extremamente necessárias para a formação de estruturas HDL estáveis (CREPALDI et al, 1998;BRAVO-SUÁREZ et al, 2004;NIU et al, 2016;JATAV et al, 2016). (BELLOTO et al, 1996;ZHOU et al, 2016;HAFSHAH et al;BHANAWASE & YADAV, 2017;DEBEK, et al, 2017).…”

“…The results of thermal analysis, X-ray diffractometry and infrared spectroscopy show that the composition changes aspects of crystallinity and thermal stability and allowed to clarify how some aspects such as interlamellar hydration and hydroxyl network stability correlate with the presence of cations modifiers. KEYWORDS: anionic clay, LDH, turbostratic effect.As argilas aniônicas com estrutura de Hidróxido Duplo Lamelar (HDL) são amplamente investigadas como adsorventes aniônicos e matrizes para catalisadores(TIMOFEEVA et al, 2016;ZHOU et al, 2016;HAFSHAH et al;BHANAWASE & YADAV, 2017;DEBEK, et al, 2017). A composição mais investigada é conhecida como Hidrotalcita e é baseada na estrutura do mineral brucita Mg(OH) 2 , mas com o cátion de magnésio parcialmente substituído por cátions trivalentes, comumente o alumínio(SHEN et al, 1994; DEL ARCO et al, 1999; CARPANI et al,…”
