Abstract

The synthesis of Ce/mesoporous silica (Ce/MS) and its lifetime determination for the hydrocracking of waste lubricant has been carried out. The MS was synthesized using tetraethyl orthosilicate (TEOS) and gelatin extracted from bovine bone as a template. Cerium was impregnated onto the MS by wet impregnation method using Ce(NO3)3.6H2O. The MS and Ce/MS were then characterized by means of acidity using ammonia base vapor adsorption, Fourier Transform Spectrophotometer (FTIR), Transmission Electron Microscope (TEM), Scanning Electron Microscope-Energy Dispersive X-ray Spectrometer (SEM-EDX), and surface area analyzer (SAA) based on the BET and BJH equation. The Ce/MS catalyst was tested in hydrocracking of waste lubricant in three runs. Lifetime of Ce/MS catalyst was determined using a linear regression of the liquid product yields vs hydrocracking time. The Ce/MS catalyst showed an acidity of 2.79 mmol/g, BJH desorption pore diameter of 3.84 nm, BET surface area of 246.55 m2/g, and total pore volume of 0.44 cm3/g. The yield of liquid product obtained from hydrocracking of waste lubricant using the Ce/MS catalyst for the first, second, and third runs was 21.42, 17.23 and 10.54 wt.%, respectively for 2.5 h per each run. Lifetime of Ce/MS catalyst in hydrocracking of waste lubricant was 12.54 h.

Abstract

Synthesis of mesoporous carbon from Merbau wood (Intsia spp.) waste by microwave method as nickel catalyst support for α-cellulose hydrocracking had been carried out. The Merbau wood sawdust was carbonized at 800 °C to produce C800 and the C800 was treated by microwave irradiation (399 W) for 5 min to produce C800MW. The Merbau wood flakes, which were only treated by microwave irradiation (399 Watts) for 30 min produced CMW. Wet impregnation technique was carried out to disperse the Ni metal (1.0, 1.5, and 2.0 wt.%) onto the best mesoporous carbon. The mesoporous carbons were analyzed by Fourier Transform Infra-Red Spectroscopy (FTIR), Surface Area Analyzer (SAA) and Scanning Electron Microscopy (SEM). The hydrocracking of pyrolyzed α-cellulose was carried out at 400 °C. The liquid product was analyzed by Gas Chromatograph-Mass Spectrometer (GC-MS). The results showed that the C800MW was the best performance carbon and it had a specific surface area, total pore volume, average pore diameter and acidity of 364.12 m2/g, 0.28 cm3/g, 3.03 nm, and 2.18 mmol/g, respectively. The Ni1.5/C800MW catalyst produced the highest conversion of liquid product (58.76 wt.%) than the Ni1/C800MW (57.51 wt.%) and Ni2/C800MW (34.18 wt.%).
