00022 Organic geochemical characterization of some Carboniferous coal seams of Zonguldak Basin (NW Turkey)
07 investigation of coal and a naphthalane pitch by 96/00019 means of the triple-echo magic angle turning experiment Hu, J. Z. et al., Energy Fuels, 1995, 9, (4), 717-726. The triple-echo magic angle turning 2-dimensional experiment together with short contact time and dipolar dephasing variations was used to investigate the structure of a series of coals and a naphthalene-derived pitch. Aromaticities obtained with the standard triple-echo MAT experiment at 4.7 T with a single contact time were compared with those obtained from the standard “C CP/MAS variable contact time experiment at a magnetic field of 2.35 T and sample spinning rate of -4.1 kHz. 96lOOO20
Mechanisms of immature oil generation In coalbearing sequences and its significance8
Zhong, N. et al., Jianghan Shiyou Xueyuan Xuebao, 1995, 17, (1). 1-7. (In Chinese) In view of the complexity of the organic matter in coal-bearing sequences and maceral oil generation by stage, the capabilities of immature oil generation of coal-bearing sequences are discussed. Based on cases of studies of earlier hydrocarbon generations from resinite and suberinite, two sorts of mechanisms of immature oil generation in coal-bearing sequences are proposed.
Multistage triaxial tests on anthracite coal in 96iOOO21 Samchok coal mine, Korea Kim, M. K. and Lee, C. I. Han’guk Chawon Konghak Hoechi, 1995, 32, (l), 72-80. (In Korean) The paper discusses one of the most important mechanical data for analysis of stress and strain around underground gangway which is that of triaxial compressive tests. In the study conventional and multistage triaxial tests on anthractie specimens were conducted to get mechanical data for underground design in Samchok Coal Mine. The data was then compared with other direct shear test results which had been published. 96100022
Or anic geochemical characterization of some Carboniferous coa9 seams of Zonguldak Basin (NW Turkey) Yalcin, M. N. NATO ASI Ser., Ser. C, Composition, Geochemistry & Conversion of Oil Shales, 1995, (455), 461-476.
The Carboniferous elastic sequence of the Zonguldak Basin, contains several coal seams that have been mined since 1848 as the only major bituminous coal deposit in Turkey. Recently, a study was initiated aimed at determining the coal-bed methane potential of the basin. Within the framework of this study, in addition to coal geology and numerical basin modelling, organic geochemical methods have been used to define the relevant properties of the coal. 96100023
Palynologic, petrographic and geochemlcal characteristics of the Manchester coal bed in eastern Kentucky
Eble, C. F. and Hower, J. C. Int. J. Coal Geol., 1995, 27, (2), 249-278. The Manchester coal bed in eastern Kentucky is the stratigraphtcally lowest coal in Kentucky that is both laterally continuous and of consistent mineable thickness. The bed occurs in the lower part of the Breathitt Formation and is equivalent with the middle Morrowan of the Eastern Interior Basin and the late Westphalian A of western Europe. The bed is consistently 0.61-0.92 m and generally is devoid of inorganic partings. 96100024

Relationship of porous characteristics of coal and moisture in coal
Kuangye (Beijing), 1995, 4, (l), 90-93. (In Xiao, B. and Zhou, X. Chinese) Describes a relationship between the pore diameter and moisture content of coal. Results from ten coals showed that pores of larger than 400 A have remarkable effect on moisture of coals.

Sorption by mineral surfaces: rebirth of the classlcal condensation pathway for kerogen formation?
Collins, M. J. et al., Geochim. Cosmochim. Acta, 1995, 59, (11), 2387-2391. Both R.G. Keil et al. (1994) and L.M. Mayer (1994) found a strong correlation between surface area and organic content in marine sediment. This finding suggests that occurrence of organic matter in marine sediments typical1 is as a monolayer sorbed to the surface of mineral grains. Theoretical Iyactors which may influence the adsorption and propagation of polymerit organic matter on mineral surfaces are considered and the likely diagenetic fate of adsorbed material is examined.
96100030 Study of coal structure by using HRTEM Ruan, C. and Zhang, P. Ranliao Huavue Xuebao, 1995,23, (1) 75-79. (In Chinese) Vitrinite is the maceral which has regularly changing property with coal structure, and it is also a main component affecting the coal quality. A high resolution TEM (HRTEM) with point resolution of 2.1 A was used to analyze the macromolecular structure of some coals of different ranks. Nonhomogeneous pore structure of anthracite macromolecules can be directly characterized by HRTEM. The degree of molecular orientation of Jingxi anthracite is stronger than that of Jincheng anthracite. The former is mainly composed of parallel aromatic stack and pre-oriented structures, while the latter granular structure. HRTEM technique is an effective method used for coal molecular structure and coalification nature studies.

Surface area and pore development during lignite
activation Yang, S. et al., Ranliao Huarue Xuebao, 1995, 23, (l), 80-87. (In Chinese) Lignite was carbonized and activated simultaneously in the fluidized bed reactor with an internal diameter of 86 mm. It was found that the gas velocity and water-vapour content significantly affected the surface area and pore volume distribution. However, the influence degree decreases after the removal of mineral matter in coal.

(In German) The linear relationships between properties and .ash content ‘were studied using coals of different kinds from 20 coalfields in 6 countries. In order to explain this behaviour, a two phase model is proposed, according to which the coal in conventional samples is believed to be formed of two phases, whose mass ratios, but not their compositions, are location dependent in the seam.
