coal
Which of the following properties is not measured during proximate analysis of coal?
density
Anthracite has higher volatile matter content than Bituminous coal.
false
Coal can be used directly to produce "pig iron" by mixing it with iron ore in a blast furnace.
false
Kerogen derived from higher plants gets converted to crude oil and natural gas when buried inside the earth for millions of years.
false
Kerogen produced from higher plants gets converted into natural gas.
false
Kerogens are formed by the transformation of inorganic matter into an insoluble, polymeric material
false
Lifetime predictions for a fossil fuel are done based on available resources.
false
United States has large crude oil reserves.
false
Kerogen formed from algae or plankton is derived from
fats, oils, waxes

The quantity of an energy source that is known to exist and that can be recovered economically is called
reserve
What is necessary for the fossil fuel formation?
temperature, pressure, time
Carbonization is the process of heating coal in the absence of air to produce coke.
true
In deep mining, coal seams are buried several hundred feet to 1000 ft. deep under the ground.
true
Coke is produced by combustion of coal in a furnace.
false
In the US, coal is primarily used for carbonization.
false
Lignite has higher heating value than Bituminous coal.
false
Lignite is the highest ranked coal.
false
Low and medium rank coals are ranked on the basis of volatile matter content.
false
Most of the natural gas reserves in the world are located in United States.
false
Proximate analysis exactly measures the elemental composition of coal.
false
Resources are the quantity of an energy source that is economically recoverable.
false
The United States is the largest exporter of coal.
false
Economic feasibility and geological assurances are two important variables that differentiate resources and reserves.
true
Fossil fuels are formed due to the interruption of the decay process in the carbon cycle.
true
Heating value of coal increases with increase in the rank of coal
true
In a fluidized bed combustion, fine coal particles are "fluidized" and burnt using a jet of hot air.
true
Kerogens are produced from algae, planktons and higher plants with the help of decomposition by bacteria.
true
Large sized coal pieces can be used during the Stoker combustion process.
true
Lignite is the youngest ranked coal.
true
Surface mining requires the removal of top soil and layers of rock to expose beds of coal.
true
The starting point of the formation of fossil fuels is the transformation of decaying organic matter to kerogen.
true
