摘要The carbonization mechanism of tripropylamine (TPA) in low-temperature hydrocracking was studied with the aim of increasing the quality and filling density of single-walled carbon nanotubes (SWCNTs) produced in the channels of AlPO4-5 crystals. The conversion process of TPA was investigated using a combination of Fourier transform infrared spectroscopy, mass spectrometry, C-13 nuclear magnetic resonance spectroscopy, thermogravimetric analysis and micro-Raman spectroscopy at various hydro cracking temperatures. During the hydrocracking process, hydrogen participated in the cracking reaction of TPA and decreased the required activation energy. The protonated TPA converted into neutral TPA at 210 degrees C. When the hydrocracking temperature exceeded 260 degrees C, dipropylamine, n-propylamine, propylene, propane, ethane and methane were produced. The hydrocracking rate of TPA increased with increasing hydrocracking temperature. A small amount of aromatic compounds was also detected in the A1PO(4)-5 crystals hydrocracked at 280-350 degrees C; this amount decreased with increasing hydrocracking temperature. The content of residual TPA and amorphous carbon compounds in the AlPO4-5 crystals also decreased with increasing hydrocracking temperature. TPA decomposed completely after hydrocracking for 10 h at 350 degrees C. SWCNTs with a diameter of 0.4 nm were synthesized at 280-350 degrees C, and the filling density of SWCNTs increased with increasing hydrocracking temperature. (c) 2017 Elsevier Ltd.
