천연가스는 메탄을 주성분으로 하는 청정한 대체연료로 자동차나 트럭 등에 압축천연가스와 액화천연가스 형태로 사용할 수 있다. 그리고, 천연가스만을 사용하는 전소엔진과 가솔린 및 천연가스를 동시에 사용할 수 있는 겸용엔진이 있으며, 특히, 겸용엔진의 경우 두가지 연료를 동시에 사용할 수 있는 것으로 정의할 수 있다. 본 연구에서는 선박용 가솔린 시스템을 인젝터, 레귤레이터, 연료탱크 및 전자제어장치로 구성된 압축 천연가스 겸용시스템으로 전환시켜 연료시스템과 동력값을 비교하였다. 그 결과, 천연가스엔진의 경우... -

Extraction and characterization of lignin from black liquor and preparation of biomass-based activated carbon therefrom
Daeyeon Kim, Jinsil Cheon, Jeonghoon Kim, Daekyun Hwang, Ikpyo Hong, Oh Hyeong Kwon, Won Ho Park, Donghwan Cho 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 14 81-88 (8 pages)
In the present study, biomass-based lignin was extracted from industrial waste black liquor and the extracted lignin was characterized by means of attenuated total reflectance- Fourier transform infrared spectroscopy and 1H-nuclear magnetic resonance spectroscopy. The extracted lignin was carbonized at different temperatures and then activated with steam at 850oC. The extracted lignin in powder state was transformed into a bulky carbonized lignin due to possible fusion between the lignin... -
Synthesize multi-walled carbon nanotubes via catalytic chemical vapour deposition method on Fe-Ni bimetallic catalyst supported on kaolin
Aliyu A, Abdulkareem AS, Kovo AS, Abubakre OK, Tijani JO, Kariim I 한국탄소학회 Carbon Letters 18 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 5 33-50 (18 pages)
In this study, Fe-Ni bimetallic catalyst supported on kaolin is prepared by a wet impregnation method. The effects of mass of kaolin support, pre-calcination time, pre-calcination temperature and stirring speed on catalyst yields are examined. Then, the optimal supported Fe-Ni catalyst is utilised to produce multi-walled carbon nanotubes (MWCNTs) using catalytic chemical vapour deposition (CCVD) method. The catalysts and MWCNTs prepared using the optimal conditions are characterized using high... -
Stabilization of pitch-based carbon fibers accompanying electron beam irradiation and their mechanical properties
Mi-Seon Park, Yoonyoung Ko, Min-Jung Jung, Young-Seak Lee 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.2 8 121-126 (6 pages)
Carbon fibers are prepared by stabilizing pitch fibers accompanying electron beam (E-beam) irradiation. The carbon fibers pretreated by E-beam irradiation achieve a higher stabilization index than the carbon fibers that are only heat-stabilized. In addition, the carbon fibers subjected to E-beam irradiation in the stabilization step exhibit a comparable tensile strength to that of general purpose carbon fibers. The carbon fibers pretreated with an absorbed dose of 3000 kGy have a tensile... -

Carbon-allotropes: synthesis methods, applications and future perspectives
P. S. Karthik, A. L. Himaja and Surya Prakash Singh 한국탄소학회 Carbon Letters 19 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.4 1 219-237 (19 pages)
The element carbon has been used as a source of energy for the past few hundred years, and now in this era of technology, carbon has played a significant and very prominent role in almost all fields of science and technology. So as an honour to this marvellous element, we humans should know about its various forms of existence. In this review article, we shed light on all possible carbon-allotropes; similarities in their synthesis techniques and the starting materials; their wide range of... -
Double-walled carbon nanotubes: synthesis, structural characterization, and application
Yoong Ahm Kim, Kap-Seung Yang, Hiroyuki Muramatsu, Takuya Hayashi, Morinobu Endo, Mauricio Terrones, Mildred S. Dresselhaus 한국탄소학회 Carbon Letters 12 Pages

Double walled carbon nanotubes (DWCNTs) are considered an ideal model for studying the coupling interactions between different concentric shells in multi-walled CNTs. Due to their intrinsic coaxial structures they are mechanically, thermally, and structurally more stable than single walled CNTs. Geometrically, owing to the buffer-like function of the outer tubes in DWCNTs, the inner tubes exhibit exciting transport and optical properties that lend them promise in the fabrication of field-effect...
