A catalyst for hydrocracking heavy oils includes iron and activated carbon, which have an MCH conversion rate of 40 to 80%, a specific surface area of 600 to 1000 m · 2 · / g, a pore volume of 0.5 to 1.4 cm · 3 · / G, a volume of mesopores with a diameter of 2 to 50 nm of not less than 60% and an average pore diameter of 3 to 6 nm, the iron in an amount of 1 to 20 wt .-%, based on the activated carbon from which activated carbon is carried. The hydrocracking process in which the catalyst is used comprises a first step of performing hydrocracking at a temperature within the range of 360 to 450 ° C at a hydrogen partial pressure of 2 to 14 MPaG and a second step of performing hydrocracking on one Temperature within the range of 400 to 480 ° C at a hydrogen partial pressure of 2 to 18 MPaG, which can suppress coke formation and with which heavy metals such as Ni and V, asphaltene, residual carbon, sulfur and nitrogen are removed from the heavy oils with high efficiency can. |
