Pyrolysis of coal-tar asphaltene in supercritical water

Journal of Analytical and Applied Pyrolysis, 2011
Abstract Pyrolysis of coal-tar asphaltene, the main active component of coal tar in supercritical water (SCW), is investigated to further understand the upgrading mechanism of coal tar. It is found that coal-tar asphaltene convert to gas, maltene and char both in N 2 and in SCW, but the conversion of coal-tar asphaltene and the yield of maltene in ...

Study on the catalytic pyrolysis of coal volatiles over hematite for the production of light tar

Journal of Analytical and Applied Pyrolysis, 2020
In this paper, to investigate the catalytic pyrolysis behavior of coal (XJ) volatiles over two hematite (HA and HB), a double-layered fixed-bed reaction apparatus, which was easy to separate coal and catalysts was employed to measure the pyrolysis tar ...

Online Analysis of Biomass Pyrolysis Tar by Photoionization Mass Spectrometry

Energy & Fuels, 2016
The online analysis of volatiles from biomass pyrolysis (or gasification or combustion) is interesting because it has the ability to sample the volatiles directly from their reactive environment. The photon ionization (PI) is an efficient and soft ionization method for online analysis of biomass pyrolysis volatiles.

Pyrolysis of Waste Polypropylene and Characterisation of Tar

European Journal of Mass Spectrometry, 2009
Waste polypropylene (PP) has been pyrolysed to obtain mainly a liquid tar product of high yield (83.5%) with the balance as gas (15.5%) and a little residue (1.0%). The elemental composition of the PP tar was: C: 87.1%, H: 12.6% and O+others: 0.4% (by difference).

A pyrolysis process for tar sands

The Canadian Journal of Chemical Engineering, 1989
AbstractA thermal processing system for tar sands is developed and analyzed. Based on the Utah tar sands studied, the process is found to be operable using combustion of coke and unconverted bitumen as the energy source. It is estimated that about 80% of the spent sand is required to be recycled to the pyrolyzer to provide this energy source.The ...

Flash pyrolysis of tar from the pyrolysis of pine bark

Journal of Analytical and Applied Pyrolysis, 1985
Abstract A mixture of tar vapours and other gases was obtained by introducing size-separated bark particles into a reactor at 650°C. This mixture was then directed through a second reactor, the temperature of which could be changed. For each temperature, the flow-rate of the mixture was varied from low to high values up to the disappearance of tar at

Pyrolysis of coal tar pitch binders

Carbon, 1972
Abstract Thermogravimetric analysis techniques have been adapted to study the thermal decomposition of six coal tar pitches. Two material constants are introduced to describe the thermal stability and/or reactivity of coal tar pitches. These constants can be correlated with the softening point of the pitches.
