Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

В результате проведения процесса перегонки каменноугольной смолы на установке АРН-ЛАБ-03 получено 9 % легкой фракции масла с температурой кипения до 170 °C, 12 % средней фракции масла с температурой кипения 170–230 °C, 10 % тяжелой фракции масла с температурой кипения 230–270 °C, 32 % антраценовой фракции с температурой кипения 270–360 °C и 55 % твердого остатка пека. Антраценовая фракция подвергается дальнейшему процессу коксования. В результате коксования антраценовой фракции в течение 5,5 ч под давлением 3,5 МПа при температуре 500 °C выход образца К-3 – 45 %. Выход образца К-4, полученный при тех же условиях, но при давлении 4,5 МПа, составил 50 %. Таким образом, предложен эффективный метод получения кокса из антраценовой фракции смолы. As a result of coal tar distillation process on the ARN-LAB-03 unit 9 % of light oil fraction with boiling point up to 170 °C, 12 % of medium oil fraction with boiling point from 170 to 230 °C, 10 % of heavy oil fraction with boiling point from 230 to 270 °C, 32 % of anthracene fraction with boiling point from 270 to 360 °C and 55 % of solid ash residue were obtained. The anthracene fraction is subjected to a further coking process. As a result of coking of the anthracene fraction for 5.5 hours under pressure of 3.5 MPa at a temperature of 500 °C the yield of sample K-3 is 45 %. The yield of sample K-4 obtained under the same conditions but at pressure of 4.5 MPa was 50 %. Thus, the method of coke production from anthracene fraction of resin is proposed.
