N2 - Ni, W, Mo and C catalysts were mixed and mechanically processed at room temperature for different grinding times: 0, 40, 80, 120, 160, 200 and 240 h. The phases at every stage of milling were studied by X-ray diffraction (XRD). The powders were used in the catalytic aquathermolysis reaction of heavy oil. X-RD showed by increasing the milling time from 0 to 240 h, nanostructured carbide phases were synthesized with a crystallite size ranging from 125.6 to 10.1 nm, which was confirmed by high resolution transmission electron microscopy (HRTEM). The performance of the nano-catalysts in the heavy oil before and after the reaction was analyzed by Fourier transform infrared spectroscopy (FT-IR). As the milling time increased, the ratio of the viscosity reduction of the heavy oil increased from 80.4% to 97.1% by using the catalyst milled for 240 h.
