“…The maximum temperature of the oven of GC could reach 300 °C. The temperature program was the same as that in a previously published literature (Li et al, 2016). Finally, all the obtained GC-MS data were subjected to a systematical analysis according to the characteristics of the aromatic ring structure of molecular of compounds.…”

The evolution behavior of the light tar during coal fast pyrolysis under inert gas, simulated fuel gas (SFG) atmosphere, and catalytic reformation of simulated (CRS) fuel gas over Ni/Al2O3 was studied in this article. The light tar was recovered from the distillation of the crude tar at the temperature of 300°C and subsequently subjected to detection through the GC-MS analysis. It was found that both SFG and CRS over Ni/Al2O3 significantly enhanced the light tar yield, but a little effect was shown on the heavy tar yield. According to the molecular structure characteristics, the compounds in the light tar could be classified into several groups: aromatic components, phenol components, aliphatic components, heteroatom components, and O-containing components (phenol compounds excluded). It was demonstrated that the selectivity of each component in the light tar varied significantly with the pyrolysis atmosphere and temperature. The evolution of the aromatic components took the dominant role in the light tar produced at high temperature. The SFG and CRS contributed markedly to enhancing the evolution of the O-aromatic components in the light tar, whereas they suppressed the evolution of the O-aliphatic components and the phenol components in the light tar at high temperature.

“…Основное требова-ние к агрегатам, в которых происходит полукоксова-ние -равномерность обогрева обрабатываемого угля (Joutsenoja, Heino, Hernberg, & Bonn, 1999;Li, Hu, & Zong, 2013;Arena & Di Gregorio, 2014). Для этого используются агрегаты с внутренним подводом теп-ла, когда газовый или твердый теплоноситель пода-ется непосредственно в него, и внешним подводом тепла, когда теплоноситель нагревает стенки камеры, в которой находится уголь (Falshtynskyy, Dychkovskyy, Lozynskyy, & Saik, 2012;Li et al, 2016;Zhang & Zheng, 2016). Существуют агрегаты, в которых полу-коксование угля осуществляется в автотермическом процессе за счет тепла от сжигания летучих продук-тов пиролиза угольных веществ и части угля или полукокса (Asanov, Asanova, & Orozov, 2016).…”

Staged condensation of coal tar was studied with a three‐staged condensation system (first stage S1, 100–300 °C; second stage S2, 30–70 °C; third stage S3, 0 °C) to perform on‐line preliminary removal of dust and fundamental fractionation of tar components. The dust and heavy components are predominantly distributed in S1. The polycyclic aromatic hydrocarbons are abundant in S1. Aliphatics and monocyclic phenols are abundant in S2, and the tar in S3 is rich in aliphatics and monocyclic aromatic hydrocarbons. With increasing S2 temperature from 30 to 70 °C, the total organics in the water phase in S2 and S3 are least at an S2 temperature of 50 °C, which is advantageous for post‐treatment of wastewater.
