Extraction of Asphaltite with Toluene

Solid Fuel Chemistry, 2018
The 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.

Salt Flotation of Şirnak Asphaltite

Energy Sources, Part A: Recovery, Utilization and Environmental Effects, 2011
Abstract The aim of this study was to investigate the possibility of cleaning Sirnak asphaltite by salt flotation. For this purpose, experimental studies were conducted on a Sirnak asphaltite sample containing high ash and sulfur content. The effects of salt amount, pH, frother amount, and impeller speed on the flotation were investigated separately in

Pyrolysis Kinetics of Asphaltite by Thermal Analysis

Petroleum Science and Technology, 2006
Abstract Pyrolysis properties and kinetic analysis of asphaltite were investigated by means of thermogravimetry (TG) and derivative thermogravimetry (DTG). Thermal experiments were carried out from ambient temperatures to 1000°C in nitrogen atmosphere at different heating rates.

Fast Pyrolysis of Şırnak Asphaltite (Turkey) and Characterization of Pyrolysis Products

Energy Sources, Part A: Recovery, Utilization and Environmental Effects, 2008
Abstract Fast pyrolysis of Sirnak Asphaltite (SASP) was investigated to determine yield and distribution of volatile products at different temperatures. A special sampling technique was used for collecting organic products formed at different time intervals and pyrolysis temperatures.

A kinetic study of Meyers' desulphurization of asphaltite

Fuel, 1989
Abstract Cizre asphaltite was leached in acidic ferric chloride solutions. The parameters affecting conversion of pyrite disseminated in asphaltite to sulphate were investigated and a mathematical model having these parameters was derived to define the leaching process.

CHROMIUM AND THALLIUM IN TURKISH ASPHALTITE SAMPLE

SGEM International Multidisciplinary Scientific GeoConference EXPO Proceedings, 2017
Asphaltite derives from petroleum origin solid fossil fuel [1]. It contains valuable elements such as chromium, thallium molybdenum, uranium etc. Chromium and thallium are very important elements both environmental and health. Chromium has an important role in the metabolism. It keeps the blood sugar level in balance.

NICKEL SPECIATION IN ASPHALTITE BOTTOM ASH

SGEM International Multidisciplinary Scientific GeoConference EXPO Proceedings, 2017
Asphaltites derive from petroleum origin. The combustion of asphaltites produces fly and bottom ashes that are characterized by a high content of valuable elements such as vanadium, nickel, molybdenum, uranium, thorium, sulfur and unburnt carbon [1].

Rheological Properties of Asphaltite−Water Slurries

Energy & Fuels, 2006
In this study, the rheological characteristics of asphaltite−water slurries (AWSs) were investigated with respect to some of the most important parameters in the preparation of slurries. The effects of pulp density, chemical addition, pulp pH, and particle size on the rheological behavior and viscosity of AWSs were studied. The role of demineralization
