METHOD OF PRODUCING REGENERATED HYDROFINING CATALYST AND METHOD OF PRODUCING PETROCHEMICAL PRODUCT Russian patent published in 2014 - IPC B01J38/02 B01J38/12 C10G45/08 C07C5/02 

FIELD: chemistry.

SUBSTANCE: disclosed is a method of preparing a regenerated hydrofining catalyst by regenerating a spent hydrofining catalyst in a given temperature range, where the given temperature range is from T₁ -30°C or higher to T₂ +30°C or lower, said temperature range being defined by conducting differential thermal analysis of the spent hydrofining catalyst, converting differential heat in a temperature measurement range from 100°C or higher to 600°C or lower into an electromotive force difference, double differentiation of the converted value on temperature to obtain the least extremal value and a second least extremal value, and presenting temperature which corresponds to the extremal value at the side of lower temperatures as T₁ and temperature corresponding to the extremal value at the side of higher temperatures as T₂. The invention also discloses a method of producing a petroleum product using said catalyst and the regenerated catalyst itself.

EFFECT: method enables to obtain a regenerated hydrofining catalyst, having a constantly high activity, from a spent hydrofining catalyst.
