The effect of nickel content impregnated on zeolite toward catalytic activity and selectivity for hydrotreating of cashew nut shell liquid oil

Abstract

This research aims to investigate the effect of various amount of Ni metal which is impregnated on Mordenite toward the catalytic activity of the Cashew Nut Shell Liquid Oil (CNSLO) hydrotreating process. The Ni/Mordenite catalysts were prepared by wet impregnation method using Ni(NO3)2 .6H2 O with the Ni content varied under 1, 3, 5 wt.% and mordenite which were dissolved in methanol and carried out drying, calcination, and reduction. Hydrotreating is carried out in a semi-batch stainless steel reactor which is flowed with H2 gas. The catalyst was characterized and analyzed by Fourier Transform Infrared, X-Ray Diffractometer, Scanning Electron MicroscopeEnergy Dispersive X-Ray Spectrometer, Transmission Electron Microscopy, Gas Sorption Analyzer, and Atomic Absorption Spectrophotometer. The total acid amount test was carried out using ammonia vapor adsorption with the gravimetric method. The liquid product of hydrotreating was analyzed by Gas Chromatography-Mass Spectroscopy. Increasing the amount of metal impregnated on mordenite will increase the total acid site, activity, and selectivity of the gasoline fraction.
