Coal and Petroleum Flashcards
Residue of non-combustible matter in coal
ash
Coal contains traces of this
iron and uranium
“Dehydrogenated plant fragments”
Macerals
Maceral maturity is estimated by
Vitrinite reflectance
Most common type of maceral? Made up of what?
Vitrinite maceral, cell wall material of plants
Maceral derived from waxy, spores, resins wc are resistant to weathering
Liptinite/exinite Macerals
Plant material strongly altered and degraded in the peat stage
inertinite Macerals
Land plants emerged during this time
Devonian period
Accumulation of coal occured during this
Carboniferous period
Fixed Carbon ____ while coal grade increases
Increases
Volatille matter ____ as coal rank increases
Decreases
Hydrogen ____ ascoal rank increases
Decreases
Oxygen content ____ as Coal rank increases
decreases
Lignite is used mostly for
Power generation
Sub-bituminous coal is used for this bc of its low S content
Power generation (also for Cement manufacture)
Bituminous coal is split into these two types
Metallurgical and thermal
Metallurgical bituminous coal is used for
Coke in Iron and steel manufacturings
Anthracite coal is used for
Domestic or Industrial smokeless fuel
