一种硅镧改性催化剂载体及其制备方法和应用
摘要：
本发明涉及催化剂领域，公开了一种硅镧改性催化剂载体及其制备方法和应用。该方法包括将改性硅油和镧化合物与氧化铝载体进行接触的接触工序，所述改性硅油为选自烷基改性硅油、聚醚改性硅油、环氧改性硅油、氨基改性硅油、聚酯改性硅油和羟基改性硅油中的一种或多种。通过本发明的方法，改善载体的表面酸量和酸强度性质，使其成为能够制备高活性加氢处理催化剂的载体。
摘要（英）：

The invention relates to the field of catalysts, and discloses a silicon-lanthanum modified catalyst carrier, and a preparation method and application thereof. The method comprises a contact step thatmodified silicone oil and a lanthanum compound make contact with an alumina carrier, specifically, the modified silicone oil is one or more of alkyl modified silicone oil, polyether modified siliconeoil, epoxy modified silicone oil, amino modified silicone oil, polyester modified silicone oil, and hydroxyl modified silicone oil. By means of the method, the surface acidity and acid strength properties of the carrier are improved so that the carrier can be used to prepare a highly active hydrotreating catalyst.
