摘      要：Catalytic activities of NiMo/MCM-41 and the mixture of Ni/MCM-41 with H-MCM-41 in cracking used ULO （lubricant oil） have been studied. This work was started by synthesis of aluminosilicate （MCM-41） at ratio of Si/AI = 50, using CTAB （cetyltrimethylammonium bromide） as a template, and TMAOH （tetramethylammonium hydroxide） as co-surfactant, where a hydrothermal process at 100 ℃ was conducted for 12 h. Organic compounds were then burned out from the dry solid material by calcination at 540 ℃. Ni/MCM-41 and H-MCM-41 were produced by ion exchange method, followed by reduction and calcination treatments, respectively, while NiMo/MCM-41 was produced by impregnation method followed by calcination. Product of MCM-41 was characterized by XRD （X-ray Diffraction）, Fourier FTIR （transform infra red spectrophotometric）, TEM （transmission electron microscopic） and BET （brunauer-emmet-teller） methods. Performance of the catalytic activities were shown by both of NiMo/MCM-41 and the mixture of 1：1 of H-MCM-41 and Ni/MCM-41 were mixed with the ULO at ratio of 1：200 （w/v） in a stainless steel reactor, then they were heated at 420 ℃. The products of cracking were analyzed using GC-MS （gas chromatography-mass spectrometry）. Results of the work showed that the MCM-41 was successfully synthesized. Using mixture of Ni/MCM-41 and H-MCM-41 catalysts, 56.6% of ULO could be converted to OLP （organic liquid product）. However, using NiMo/MCM-41 catalyst only 28.5% OLP could be produced. GC-MS analyses showed that cracking of the ULO at 420 ~C using NiMo/MCM-41 catalyst gave conversion 4.3% and 8.8% to gasoline like and diesel like fractions, respectively, while using mixture of Ni/MCM-41 and H-MCM-41 catalysts, conversion of 12.2% and 14.8% respectively to gasoline like and diesel like fractions were obtained.
