Disclosed are a unsupported catalyst for deeply hydrofinishing of intermediate distillate and method for making the same, particularly a catalyst particle with nanometer pore and relatively high specific surface area obtained by urea melt reaction. The most outstanding technical feature of the invention is that by adopting synthesis technique of urea melt reaction, metal is free of loss, prepared metal composite has nanometer pore and relatively high specific surface area, and could provide abundant catalytic hydrogenation activity bits, and the inventive catalyst has much higher catalytic hydrogenation activity comparing with conventional supported catalyst because of this. Meanwhile, the invention is simple in process, easy to operate, fast in reaction, suitable for industrial production.
