Bifunctional Catalysts in Hydrogenation for Oil Processing
A new approach to the rpeparation of highly active bifunctional catalysts of hydrogenation processes providing an increase in the extent of oil processing and obtaining motor fuel in agreement with the world standards is proposed. This approach is based on the preparation of the support containing acidic components, and on purposive selective synthesis of the active component of hydrogenolysis and hydrogenation - Co(Ni)-Mo(W)-S-phase. The latter is localized in the catalyst in such a manner that it is available for all the raw material components to be transformed catalytically. The preparation procedure is based on the solution synthesis of bimetal compounds that are precursors of the active component. Within the framework of the proposed approach, highly active cataltysts intended for hydrocracking and hydropurification of various oil distillates can be obtained.
