weight, high manufacturing costs, and electromagnetic wave emissions [1,2]. To resolve these problems, carbon materials with good electrical conductivity, such as carbon fibers, graphite fibers, carbon nanotubes, and carbon black, have been examined as heating materials [3,4]. Among these carbon materials, graphite fibers possess many advantages compared to carbon fibers such as good mechanical and electrical properties, excellent chemical stability, high thermal conductivity, and so on [5-7]. -

한국탄소학회 Carbon Letters 2017, Vol.24 4 28-35 (8 pages)
We demonstrated an effective way of preparing melt spinnable mesophase pitches via catalytic hydrogenation of petroleum residue (fluidized catalytic cracking-decant oil) and their subsequent thermal soaking. The mesophase pitches thus obtained were analyzed in terms of their viscosity, elemental composition, solubility, molecular weight, softening point and optical texture. We found that zeolite-induced catalytic hydrogenation under high hydrogen pressure contributed to a large variation in the... -
Preparation of carbon discs using petroleum-based binder pitch reformed with carbon black
Sangmin Lee, Kyung Hoon Kim, Young-Seak Lee 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2017, Vol.23 13 84-87 (4 pages)
coal tar-based pitches and petroleum-based pitches. The raw materials of the petroleum-based pitch are obtained through petroleum refining processes, such as fluidized catalytic cracking decant oil, vacuum residue and pyrolyzed fuel oil (PFO). These residue oils are reformed to petroleum-based pitches that are solid at room temperature and for which the molecular weight is controlled through cyclization, aromatization and polymerization conducted using high-temperature heat treatment [9-13]. -

한국탄소학회 Carbon Letters 2017, Vol.23 7 48-54 (7 pages)
additive during the pitch synthesis reaction of pyrolyzed fuel oil (PFO). Two effects are generated by adding MP. One is an enhancement of thermal stability due to the high thermal property of the additive; the other is that the volatile compounds that were removed by vaporization of PFO during the thermal reaction can participate in the pitch synthesis reaction (PFO→pitch) more efficiently. The effect differs according to the amount of the additive. When the amount of the additive is less than... -
Effects of coal tar pitch addition on the wear behavior of carbon/carbon composites
Young Chan Jung, Duk Soo Kang, Kyong Yop Rhee, Soo Jin Park, David Hui 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 9 62-65 (4 pages)
Carbon/carbon (C/C) composites are acknowledged as high performance materials because of their good mechanical properties such as wear resistance, even at the higher temperature, due to their low thermal expansion [1-5]. Their hardness and light weight in addition to their superior mechanical properties at high temperature make C/C composites the best material to make brakes for aircrafts and other high weight vehicles. Accordingly, a number of studies have been conducted on the performance of... -
A review: role of interfacial adhesion between carbon blacks and elastomeric materials
Min-Joo Kang, Young-Jung Heo, Fan-Long Jin, Soo-Jin Park 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 1 1-10 (10 pages)
Carbon blacks (CBs) have been widely used as reinforcing materials in advanced rubber composites. The mechanical properties of CB-reinforced rubber composites are mostly controlled by the extent of interfacial adhesion between the CBs and the rubber. Surface treatments are generally performed on CBs to introduce chemical functional groups on its surface. In this study, we review the effects of various surface treatment methods for CBs. In addition, the preparation and properties of CB-reinforced... -

Subhash Kumar, Manoj Srivastava 한국탄소학회 Carbon Letters 12 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.3 3 171-182 (12 pages)
s (CLO-1, CLO-2) obtained from fluid catalytic cracking units of different Indian petroleum refineries, were taken as feed stocks. A third petroleum residue, aromatic extract (AE), was produced by extraction of one of the CLO-1 by using N-methyl pyrrolidone solvent. These petroleum residues were thermally treated at 380°C to examine their mesophase formation behavior. Mesophase pitches produced as a result of thermal treatment were characterized physico-chemically, as well as by instrumental... -
Novel reforming of pyrolized fuel oil by electron beam radiation for pitch production
Jin-Young Jung, Mi-Seon Park, Min Il Kim and Young-Seak Lee 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 5 262-267 (6 pages)
Pyrolized fuel oil (PFO) was reformed by novel electron beam (E-beam) radiation, and the elemental composition, chemical bonds, average molecular weight, solubility, softening point, yields, and density of the modified patches were characterized. These properties of modified pitch were dependent on the reforming method (heat or E-beam radiation treatment) and absorbed dose. Aromaticity (Fa), average molecular weight, solubility, softening point, and density increased in proportion to the... -

Kap Seung Yang, Bo-Hye Kim, Seong-Ho Yoon 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.3 2 162-170 (9 pages)
Pitch is an attractive raw material for carbon fiber precursors due to its low cost stemming from its availability as a residue of coking and petroleum processes. Ford Motor Company reported a carbon fiber target price of $11.0/kg by using a fast cycle-time manufacturing method with carbon fiber in an inexpensive format, allowing for an average retail price of gasoline of $3.58/gallon. They also recommended the use of carbon fiber with strength of 1700 MPa, modulus of 170 GPa, and 1.5%... -
Preparation of pitch from pyrolized fuel oil by electron beam radiation and its melt-electrospinning property
Jin-Young Jung, oung-Seak Lee 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 10 129-135 (7 pages)
Spinnable pitch for melt-electrospinning was obtained from pyrolized fuel oil by electron beam (E-beam) radiation treatment. The modified pitch was characterized by measuring its elemental composition, softening point, viscosity, molecular weight, and spinnability. The softening point and viscosity properties of the modified pitch were influenced by reforming types (heat or E-beam radiation treatment) and the use of a catalyst. The softening point and molecular weight were increased in...
