“…When applied to Indian coals from Argada and West Bokaro coals (Singh et al 2015;Singh and Mrityunjay 2018b) the model indicated that the coals were best used as blending coking coals because of the high amount of reactive macerals found in them.…”

“…The chemical constituents present in coal structure impact greatly on its mechanical behavior. The composition of organic matter and its degree of decomposition led to varying coal strength and modulus of elasticity of different coals (Pan et al 2013;Singh and Mrityunjay 2018b;Ahamed et al 2019) as the chemical structure was altered. Coals of low rank have a high concentration of aliphatic carbon (C al -C al ) bonds while those of high rank are highly concentrated with the aromatic-aliphatic carbon (C ar -C al ) and aromatic carbon (C ar -C ar ) bonds.…”

Coal due to its relatively large quantities and wide distribution worldwide has generated renewed interest in research and development with the aim of establishing coal conversion technologies that are technically reliable, environmentally and economically feasible. It has proved to be a prominent energy source in emerging markets with increasing energy demand by accounting for the largest increase in the demand of energy amongst all other energy sources. Furthermore, with its higher mesophase content, coal tar is an appropriate raw material for precursors in the production of carbon fiber. However, whenever a material is put to use, it is important to be able to associate its properties to the behavioral characteristics during a conversion process so as to have a basis for opting for the material in a given process or adjusting the operating conditions in order to optimize the material utilization. Therefore, as with any other material, it is important to be able to relate the properties of coal to its utilization. A review was carried out on the influence of coal properties on four main utilization technologies: gasification, carbonization, liquefaction and carbon fibre production. Among several properties rank, type, mineral matter content, distribution of trace elements, structural composition and pore structure were found to be most influential on the behavior of coal during conversion processes.

Batubara Sorong yang berada pada Cekungan Salawati memiliki potensi untuk dikembangkan. Penelitian detail mengenai batubara Sorong sangat dibutuhkan terutama penelitian mengenai lingkungan purba pada saat batubara diendapkan. Penelitian ini menjadi menarik karena posisi batubara Sorong yang secara stratigrafi regional masuk pada endapan aluvial dan litoral yang berumur kuarter. Untuk itu tujuan utama penelitian ini adalah mengetahui jenis maseral penyusun batubara dan menentukan lingkungan purba pengendapan batubara. Upaya dalam mencapai kedua tujuan tersebut maka digunakan dua metode penelitian yakni survei lapangan (pemboran cutting) dan analisis petrografi. Hasil analisis petrografi didominasi jenis grup maseral vitrinite (huminite) berkisar antara 76,5-87,8%. Lingkungan pengendapan batubara berdasarkan dua klasifikasi diinterprestasikan lingkungan limnic (terendapkan di rawa danau). Sedangkan untuk interprestasi lingkungan persediaan bahan makanan berdasarkan analisis menunjukkan rawa rheotrophic.
