“…In addition, coking value increased by adding a certain amount of BC, thus the increase in the degree of polymerization of CTP by BC is illustrated experimentally. The results after adding a dosage of 10 wt.% BC in CTP agreed with those reported by Brzozowska et al [11]. The pitch-polymer containing 10 wt.% poly(vinyl chloride)-PVC composition clearly improved anisotropy during carbonization.…”

“…Thus, this study has explored modification issues. Previous studies have shown that the structure of char can be improved by adding polymers such as polystyrene [10] and PVC [11], divinylbenzene monomers [12], or benzaldehyde [13]. For the modification reactions of CTP, catalysts are required.…”

“…As for the effect of plastic type, there have been many studies on the influence of plastic addition on coal-caking property and coke quality [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. It was revealed that thermal decomposition products of plastics interacted with bituminous coal during carbonization in a coke oven.…”

To help in building a recycling-oriented sustainable society, Nippon Steel & Sumitomo Metal Corporation developed a waste plastic-recycling process using coke oven and put it into commercial operation in 2000. Now roughly 200,000 tons per year of waste plastics are processed in coke oven in Japan. In this process, the waste plastics collected from households are agglomerated to the sizes ranging from 20 to 30 mm in diameter and charged into coke ovens with coal at the blending ratio of about 1 mass%. Waste plastics are thermally decomposed into approximately 20 mass% coke, 40 mass% hydrocarbon oil (tar and light oil) and 40 mass% coke oven gas, which are utilized as iron ore-reducing agents in blast furnaces, raw materials for the chemical industry, and a fuel for power plants, respectively. Moreover, 92 mass% of the chlorine in waste plastics is released and absorbed by the ammonia liquor spray for cooling hot coke oven gas and converted to ammonium chloride. The waste plastic-recycling process using coke ovens is superior in that a large amount of waste plastics can be treated, useful materials can be recovered using the existing facilities, coke quality can be kept the same and the chlorine released from waste plastics can be fixed in the existing ammonia liquor spray system.

“…5 There has been a great effort to synthesize graphite at as low a temperature as possible by using various additives, which consist of two main classes. [6][7][8][9] Much research has been done to enhance the properties of CTP by additives, and many investigators have reported treatment procedures that improve the carbonization behavior of CTP.…”

In this study, the influence of the addition of carbon nanotubes (CNTs) and carbon black (CB) on the graphitization temperature and microstructure of coal tar pitch (CTP) are investigated. X-ray diffraction patterns of carbon residues indicate that minimum interlayer spacing (d 002 ) values are obtained at 2000C for CTP/CNT. Moreover, the Raman spectrum of CTP/CNTs is similar to graphite, and the relative intensity of Raman lines shows that CTP/CB is less graphitized at 2000 C. In addition, scanning electron microscopy images show that when CB is added sample textures tend to disordered morphologies. However, CNTs, not only improve the morphology of CTP, but also act as nuclei for the growth of graphite flaky crystallites. The role of the CTP/CNT interface and the defects of CNTs on the graphitization degree are studied using transmission electron microscopy, and a mechanism for the graphitization of CTP, in the presence of CNTs, is proposed.
