METHOD OF INITIATING CATALYTIC PROCESS Russian patent published in 2013 - IPC C10G49/24 C10G45/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of initiating a hydrotreatment process on a bulk metallic catalyst, involving the following steps: i) providing a stream of hydrocarbon material containing less than 100 ppm of nitrogen-containing compounds; ii) adding the nitrogen-containing compound to said stream of hydrocarbon material; and iii) contacting the obtained stream of material with said bulk metallic catalyst in the presence of hydrogen and sulphur-containing compounds, where the bulk metallic catalyst is a composition of general formula (I): (X)_b(M)_c(Z)_d(Y)_e, where X represents at least one group VIII metal, M represents a group VIb metal, Y represents one or more elements selected from oxygen and sulphur, Z, together with an oxygen component in form of element Y, forms a refractory inorganic oxide, and b, c, d and e represent relative values of molar content. The invention also relates to another method for hydrotreating hydrocarbon material.

EFFECT: preventing formation of nickel sulphide on the catalyst and loss of product output.
