The bases of directional synthesis of new highly efficient and selective catalysts of catalysts for oil fraction hydrodesulfurisation based on trioctahedral smectites obtained under non-hydrothermal conditions have been developed. The main regularities of this . synthesis and its optimal conditions were determined. For the first time, synthetic clays were modified by means of the solid state ion exchange. The main regularities and optimal conditions of this process were established. It was found that synthetic stevensite is an optimal carrier for sulfided СоМо, NiMo and NiW phases; the use of the complexing agent NTA is a key factor of increasing activity, selectivity and thermal stability of developed catalysts. The active phase optimisation was performed and model of the active sites formation was proposed Product Description popup.authors popup.nrat_date 2020-04-02 Close
