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(NO 3 ) 2 ꞏ6H 2 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 H 2 gas. The catalyst was characterized and analyzed by Fourier Transform Infrared, X-Ray Diffractometer, Scanning Electron Microscope-Energy 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.

Synthesis of Co-NH 2 /mesoporous silica bifunctional catalyst for conversion of used cooking oil into biofuel was carried out. Synthesis of mesoporous silica (MS) was done by the hydrothermal method using silica from Sidoarjo mud and gelatin from bovine bone as a template. Weight ratio variation of silica/gelatin was 4, 6, and 8 produced MS4, MS6, and MS8 respectively characterized by FTIR. The MS with minimum gelatin content after calcination (MS8) was identified using FTIR, TEM, and SAA. The impregnation of Co into the MS8 was done by the wet impregnation method and the Co/MS8 catalyst was analyzed using XRF and acidity test with NH 3 vapor adsorption. Functionalization of NH 2 into the MS8 and Co/MS8 was done by the grafting method and the products were characterized using FTIR. The catalytic activity test in used cooking oil hydrocracking was done by thermal (without catalyst), physical mixture of Co/MS8 and NH 2 /MS8 catalyst, and Co-NH 2 /MS8 bifunctional catalyst. The hydrocracking liquid products were investigated by GC-MS. The MS8 had a specific surface area of 666.76 m 2 g -1 , a pore diameter of 4.9 nm, and a pore volume of 0.46 cm 3 g -1 . The Co-NH 2 /MS8 bifunctional catalyst produced the highest liquid product of 97.62 wt.% in the hydrocracking of used cooking oil with selectivity for gasoline and diesel fraction of 3.02 and 46.86 wt.%.

Cobalt and/or Molybdenum based catalysts were simply dispersed on γ-Al2O3 through wet impregnation. The set of prepared monometallic and bimetallic catalysts of aCoO/γ-Al2O3, aMoO/γ-Al2O3, aCoOaMoO/γ-Al2O3, and bCoObMoO/γ-Al2O3 were investigated and evaluated in the hydrocracking of Calophyllum inophyllum (CIO) which is not a food crop as well as rich in unsaturated fatty acid that potential to be converted into biofuel. Out of the prepared catalysts, aCoOaMoO/γ-Al2O3 with total   metal content, acidity, and specific surface area of 13.62 wt%, 5.01 mmol.g-1, and 107.67 m2.g-1, respectively, showed the best catalytic performance. The high metal loading of aCoOaMoO/γ-Al2O3 is favorable by producing 65.56 wt% liquid fraction through carbocation formation mechanism. It was selective to produce 8.61 wt% gasoline and 5.01 wt% diesel. Copyright © 2020 BCREC Group. All rights reserved
