Abstract:
Liquefaction of low-rank coal has been done to optimize the utilization of low-rank coal, which is less economical for obtaining alternative fuel oil. Coal samples were taken from the Bukit Pinang coal mine, Samarinda Ulu, East Kalimantan. Coal was liquefied using the NEDOL procedure at PUSPITEK, Serpong, South Tangerang, Indonesia. This Bukit Pinang coal liquefaction produces five fractions consisting of Naphta, Light Oil (LO), Middle Oil (MO), Heavy Oil (HO), and Coal Liquid Bottom (CLB) fractions. The liquefaction yield was dominated by the HO and CLB fractions (> 50% by weight). The nap

Abstrak Pembangkit listrik tenaga uap adalah pembangkit listrik yang menggunakan batubara sebagai bahan bakarnya. Batubara merupakan jenis batuan sedimen, dengan kandungan karbon sebagai mineral utama dan juga hidrogen, belerang serta oksigen dalam mineral sekundernya. Tingginya kandungan senyawa ini membuat batubara mudah terbakar. Di Indonesia, dengan meningkatnya kegiatan industri dan meningkatnya jumlah penduduk, maka kebutuhan energi listrik juga semakin meningkat. Upaya yang dapat di tempuh oleh perusahaan untuk mendapatkan biaya operasi yang ekonomis adalah dengan mengganti pemakaian ba

Abstract The implementation of downstream coal policies in Indonesia is regulated in Law Number 3 of 2020 to optimize coal’s domestic use and value-added. The policy is also supported by the issuance of fiscal, non-fiscal, and regional incentives. In Law Number 3 of 2020, the government of Indonesia states six types of coal downstream: coal upgrading; coal briquetting; cokes making; coal liquefaction; coal gasification; and coal slurry, yet the government has not defined which downstream coal products should be prioritized. Several parameters must be considered in implementing the downstream c

Abstract:
Currently, natural gas is considered by most countries as the main source of energy, since it is the cleanest of all hydrocarbon fuels. So, the countries of the European Union have already announced their intention to completely abandon coal, in the production of electricity, in favor of natural gas by 2030. A similar policy is being pursued by the countries of the Asia-Pacific region, although they do not specify any specific deadlines. At the same time, natural gas is transported in two ways — using a pipeline and in liquefied form. The main advantage of the second method is that after lique

Abstract:
Abstract Hydrogen is a commercially important element. Basically, there are several methods of hydrogen production that have been commercially used, such as Steam Methane Reforming (SMR), High Temperature Steam Electrolysis (HTSE), and thermochemical cycles, like Sulphur-Iodine (SI). Among these methods, SMR is the most widely used for large-scale hydrogen production, with conversion efficiency between 74–85% and it has commercially used in some fertilizer industries in Indonesia. Steam reforming is a method to convert alkane (natural gas) compounds to hydrogen and carbon dioxide (synthetic ga

Abstract:
A section of the Sangatta coalfield in the Balikpapan formation located in Kutai Basin, East Borneo, Indonesia, is the Inul area, located North of Pinang Dome. This section of the coalmine has coals with low calories (ca. 4379 cal/g), which is why they cannot be used optimally yet. The reasons of using low calorie coals are besides from being used as a mixing ingredient for the blending process of high calorie coals, they are also used to diversify the coals through the process of coal liquefaction (coal to liquid). In order for the coal liquefaction to be processed correctly, there needs to b

Abstract:
Since the coal characteristic is the main controlling factors in coal liquefaction, thus five coal seams with different coal rank from Warukin Formation in Tabalong Area, South Kalimantan have been used in this study. Three seams were low rank coal (Wara 110, Wara 120, Wara 200) while two seams were medium rank (Tutupan 210 and Paringin 712). The objectives of this study was to investigate the effect of coal rank on the rate of coal conversion factor. Coal liquefaction was conducted in an autoclave on low pressure (14.7 psi) and temperature 120°C. Experiments were designed with time intervals
