Optimization of Catalyst Hydrogenation Technology for White Oil Production Based on Medium Pressure Hydrogenation

Because the requirements of environmental protection are becoming strict, the preparation of petroleum products such as white oil needs to be harmless. In order to produce high-grade white oil products, it is necessary to study the medium-pressure hydrogenation technology and the suitable high-activity hydrogenation catalyst. The medium-pressure hydrogenation technology is proposed to produce white oil by a one-stage hydrogenation process under 7-8 MPa hydrogen partial pressure. The paper optimized the optimum conditions for medium-pressure hydrogenation of white oil. The initial reaction temperature was 210°C. The reaction pressure was 8 MPa. The liquid space velocity was 0.4 h-1. The hydrogen oil ratio was 500:1 V/V. The catalyst life evaluation experiment was carried out. The research results can provide a basis for the selection of hydrogenation catalysts.
