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.

Effects of using asphaltite as filler on mechanical properties of hot mix asphalt [PDF]

Construction and Building Materials, 2011
This study focuses on determining the engineering characteristics of hot mix asphalt using mineral filler with asphaltite. Since asphaltite which consists of high amount of sulfur leads to air pollution when used as a heating material and also being ...

Improvements on combustion properties of asphaltite and correlation of activation energies with combustion results

Fuel Processing Technology, 2006
Processing of Sirnak Asphaltite sample by gravity and flotation concentration methods was investigated to decrease its ash content. Finely disseminated inorganic constituents of asphaltite revealed the difficulty of operation.

Molybdenum speciation in asphaltite bottom ash (Seguruk, SE Anatolia, Turkey)

Fuel, 2012
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.

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.
