The moving bed residue hydrogenatio

The moving bed residue hydrogenation technology has not yet been widely used in industry. Movable bed hydrogenation technology is less mature than fixed bed hydrogenation technology. The reactor structure is complex, the equipment investment is relatively high, the operation is difficult, the control system requirements are high, the continuous addition and extraction of catalyst is difficult to achieve, and its fine particles will enter In the subsequent fixed bed reactor, the bed delamination rises. The moving bed residual oil hydrogenation technology has not made great progress in recent years, and there are few studies. It is not used as an effective method for the residual oil hydrogenation process.
