Extraction of Asphaltite with Toluene
Solid Fuel Chemistry, 2018The extraction of asphaltite with toluene was carried out at 100–300°C. With the use of X-ray fluorescence analysis, the effect of the extractant on the redistribution of organic substances between the initial and extracted asphaltites was found.

Selective oil agglomeration in Sırnak asphaltite beneficiation
Fuel, 2004Abstract In this study, the possibility of cleaning Sirnak asphaltite by the agglomeration method was investigated. Experimental studies were conducted on the asphaltite sample with ash, sulphur, volatile matter and fixed carbon contents of 44.8, 6.0, 38.0, and 17.2 wt%, respectively. For this purpose, laboratory tests were carried out to investigate

High-sulfur asphaltites of Argentina
Solid Fuel Chemistry, 2007The results of advanced study of the chemical nature of asphaltites from Rafaelita and Toribia fields, as well as the composition and structural features of their malthene, asphaltene-carbene, and carboid components are presented. It was found that the structural units in the molecules of isolated compounds are primarily based on fused tetra-and ...

Asphaltites: Composition and Conversion
1995Turkey has insignificant reserves of crude oil and natural gas. Consequently, the amount of foreign currency spent on importation of petroleum and electricity is equivalent to the total exportation from the country. The increasing trend in crude oil prices, is an important threat to the industrialisation of Turkey.

Thermal liquefaction of natural asphaltites
Solid Fuel Chemistry, 2007Thermal transformations of high-sulfur asphaltites of Argentina were studied over a wide range of their heat treatment conditions: the final heating temperature from 350 to 600°C, the nature of the solvent used (water, deacon, tetragon, straight-run petroleum diesel distillates, the process mode (batch or flow), and the presence of a catalyst.
