FIELD: chemistry.

SUBSTANCE: method provides the substrate material of titanium-bearing catalyst by means of (i) the substrate material contact catalyst with organic compound of titanium. Catalyst substrate material is selected from the group consisting of (a) the predecessor of the substrate catalyst containing aluminium connection that turns into a substrate of catalyst in the form of one or more aluminium oxides on ignition, and (b) substrate catalyst represents the aluminium oxide in the form of one or more aluminium oxides. And when this organic compound of titanium is a compound of titanium, which is associated with at least one oxygen atom of at least one organic group through communication, or (ii) joint hydrolysis of a hydrolysable organic titanium compound and Al (OR")₃, and the titanium-containing support material of the catalyst then contains Al. The hydrolyzable organic titanium compound is a titanium compound in which titanium is bonded to at least one oxygen atom of at least one organic group through a bond. All of R" are the same or different, and each is an organic group. Annealing of titanium-bearing substrate material of catalyst is carried out at a temperature above 900°C with obtaining modified catalyst substrate, which contains more than 1 wt % and less than 3.5 wt % Ti, mass-based modified catalyst substrate with Ti is in the form of one or more compounds of titanium. The invention also relates to methods of obtaining the catalyst and catalyst's predecessor, as well as to the method of synthesis of hydrocarbons.

EFFECT: lower costs.
