FIELD: chemistry. ^ SUBSTANCE: invention pertains to use of raw compositions, consisting of oil, coal and petrochemical components for production of technical carbon. The working mixture of raw materials contains a heavy pyrolysis resin, benzol distillation residue, a fraction for recycling coal-tar resin and a product of catalytic cracking of distillation fractions of primary crude oil processing, in the presence of a zeolite-containing catalyst. The catalyst product cracking is in form of a heavy gasoil cut, boiling off in the 270-420 C range, or a mixture of a heavy gasoil cut and a residue, boiling off at over 420 C, taken with mass ratio of (65-97):(3-35) %. At 20 C, the above mentioned product has density of less than 998 kg/m3, coking capacity of not more than 5.5 % and a correlation index of 102-125. ^ EFFECT: lower coking capacity of the working mixtures; increased output of technical carbon. ^ 1 tbl, 5 ex |
