Quite different from the Canadian oil sands in oil content/composition, mineral composition, and particle size distribution, the carbonate Indonesian asphalt rocks (oil-wetted) are proven to be poorly extracted by the commercial hot-water-based extraction (7.8% bitumen recovery at 50 °C and pH 9.0). Great enhancement was obtained using …

In this research, a series of combustion experiments of Indonesian oil sands using a thermal analyzer were conducted at three heating rates (10, 20, and 50 °C min− 1) over the temperature range ...

The basic properties of three Indonesian oil sands have been investigated. The results show that since the high content of volatile, heating value and oil yield, Indonesian oil sands could be combusted for power generation and retorting for oil refining. Moreover, oil sand ash with the low content of fixed carbon and high content of CaO, could not only be …

The results of the study obtained the structural information of some aliphatic groups. Zheng et al., 2018 (Zhang et al., 2018) performed the fraction separation of Indonesian oil sands bitumen using a dichloromethane/n-heptane solvent mixture. Then the samples were characterized chemically using liquid 1³C NMR combined with DEPT …

In this research, a series of combustion experiments of Indonesian oil sands using a thermal analyzer were conducted at three heating rates (10, 20, and 50 °C min − 1) over the temperature range of 20–900 °C under atmospheric pressure. The obtained DTG curves revealed that combustion reactions occurred at three different stages in all the …

Section snippets Sample. Oil sands mainly comes from Indonesia. Previously dehydrated in a paper-mill, the deinking sludge went through air-dry, grounding, and oven-dry at 105 °C for 6 h, finally the obtained particle size of oil sand was kept between 0 and 0.2 mm.They were prepared according to the ASTM standards.

At the end of 2020, Indonesia had approximately 2.4 billion barrels worth of proven oil reserves accounting for approximately 0.1 percent of the world's total oil reserves.

Indonesian oil sands. Although the characteristics of three samples differ from one another in several aspects, there are some notable similarities can be presented as follows: Indonesian oil sands are composed mostly of ash and volatile, with very little content of fixed carbon and moderate content of moisture.

The pyrolysis behaviors of oil sand from Indonesia were investigated by thermogravimetry coupled with Fourier Transform infrared Spectrophotometer(TG-FTIR) and in a fixed bed reactor, respectively.

Relative to the oil sands all over the world, the activation energy of Indonesian oil sand has a moderate value. Based on the result of the ( E ) value, the kinetic mechanism for the major oil-producing stage for S1 and S2 could be determined using the integral master plot method.

ABSTRACT: In this research, pyrolysis experiment of Indonesian oil sand was performed in a fixed bed. Results show that the temperature and heating rate had significant …
