Abstract A series of transition metals M (M = Fe, Co, Ni) modified SiO2 catalysts were prepared by sol-gel method and coated on the inner wall of stainless steel tubes, in order to develop the micro-channel reactors. Cracking of methylcyclohexane (MCH) over the micro-channel reactors with coated catalysts was investigated under supercritical conditions. Meanwhile, the structure properties of the catalysts had been analyzed by some characterization technologies, such as N2 adsorption-desorption, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), temperature-programmed desorption of NH3 (NH3-TPD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM) and X-ray fluorescence method (XRF). The results showed that the cracking activity and endothermic capacity of MCH increase by following order: Thermal cracking
