The moving bed hydrogenation techno

The moving bed hydrogenation technology has the following advantages: ① can process high-metal and high-residue carbon residue raw materials; ② extend the service life of fixed-bed catalysts and reduce the cost of catalysts; ③ shorten the downtime and extend the fixed-bed residue hydrogenation device The operating cycle is equivalent to increasing the total processing capacity; ④ solves the blocking problem that often occurs in the protection reactor; ⑤ can realize online addition and discharge of the catalyst, the total amount of waste catalyst is reduced, the catalyst utilization rate is high, and the metal concentration is increased, which is beneficial to recycling Among the metals. If the residual carbon of the residual oil raw material to be processed is less than 20% and the mass concentration of the metal (Ni + V) is 200-400 µg / g, the moving bed residual oil hydrogenation technology can be selected.
