Description

technical field

[0001] The invention relates to an alumina carrier containing silicon and boron, in particular to a catalyst carrier for hydrogenation treatment of heavy distillate oil containing silicon and boron and a preparation method thereof. Background technique

[0002] As we all know, alumina, as a carrier material, has a very wide range of applications in the field of catalysis, especially in the field of catalytic hydrogenation. But, aluminum oxide is used as catalyst carrier acid weak, and mainly L acid, and B acid is then extremely weak or does not think to contain B acid; It is easy to strongly interact with metal active components to form inactive species (such as easy to react with nickel form nickel-aluminum spinel). Simply using alumina as a catalyst carrier is prone to sintering of the metal active component or carrier, which affects the activity and stability of the catalyst. Therefore, when used as a catalyst carrier, one or several other elements are us...
