What's the difference between anthracite and lignite?

Anthracite


Definition:

  • (n.) A hard, compact variety of mineral coal, of high luster, differing from bituminous coal in containing little or no bitumen, in consequence of which it burns with a nearly non luminous flame. The purer specimens consist almost wholly of carbon. Also called glance coal and blind coal.

  • (13) Total mutagenic activity (the activity per gram of coal pyrolyzed), however, varied with coal type according to the order: high volatile bituminous much greater than subbituminous = lignite much greater than anthracite, due primarily to high organic yield during high volatile bituminous coal pyrolysis.
  • (14) Similar experiments conducted with water extracts show that bituminous, lignite, and peat, but not sub-bituminous extracts, induced SCEs, and that anthracite was equivocal.
  • (15) The specific mutagenic activity (i.e., the activity per unit sample weight) of extracts from particulates and volatiles captured on XAD-2 resin varied with coal type according to the order: subbituminous greater than high volatile bituminous greater than lignite greater than anthracite.
  • (16) Given that there is enough anthracite coal down there to burn for another 250 years, most people have long since abandoned Centralia (although remarkably, Bill Bryson found 10 people still in residence when he visited to research his book A Walk In The Woods in 1996).

  • (19) The reactivity of the newly produced free radicals in the anthracite dust correlated with the dust's toxicity.
  • (20) An experiment on rats in vivo with bituminous, anthracitic and brown coal dusts from eight coal mines showed that the fibrogenic degree in experimental rats was related to the free silica contents of the coal dust, which varied from 0.72% to 9.84% in our experiment.

Lignite


Definition:

  • (n.) Mineral coal retaining the texture of the wood from which it was formed, and burning with an empyreumatic odor. It is of more recent origin than the anthracite and bituminous coal of the proper coal series. Called also brown coal, wood coal.

Example Sentences:

  • (5) Coals and lignites having typical concentrations of 238U emanate no more 222Rn than do comparable masses of typical soils.
  • (6) If we face fiscal difficulties from abroad in the medium term, then to burn more lignite instead of importing energy will seem a wise thing to do,” a Syriza source said.
  • (7) The fee would have forced operators to buy extra certificates for their emissions from the European Trading Scheme for CO2 emission allowances, thus making electricity from lignite less profitable.
  • (8) This can largely be attributed to an increase in the use of lignite for electricity production.
  • (9) To build one new lignite plant but replace two others which are of older technology and emit more pollution, could be seen in technical terms as an improvement,” Harris Konstantatos, a member of Syriza’s central committee, told the Guardian, from Athens.

  • (11) At the same time, electricity from lignite became cheaper due to another factor: As economies throughout Europe weakened due to the global financial crisis, companies reduced their production and thus had to buy fewer EU certificates for emitting CO2.
