Abstract
The present invention relates to petrochemistry, specifically to a sintering aid composition for manufacturing carbonaceous articles for the metallurgical industry. The sintering aid composition for manufacturing carbonaceous articles consists of a concentrated residue from slurry-phase hydrocracking of heavy oil feedstock, has a content of aromatic hydrocarbons in the range from 23 to 27 wt. %, wherein the sintering aid composition is characterised by a total weight loss from 50 wt. % to 51 wt. % in the temperature range from 30 to 850° C., wherein the weight loss in the temperature range from 290 to 570° C. is about 95 wt. % of the total weight loss. Performance characteristics of the sintering aid are improved to manufacture high-strength carbonaceous articles for the metallurgical industry.
