These include heat from the partial combustion, a gaseous mixture called syngas that can be burned as fuel, and a heavy oil.
The syngas is exposed to particles of iron oxide--that is, rust--which act as an oxygen carrier.
The syngas would then be run through a process that converts syngas into liquid fuels.
The new process partially gasifies coal at elevated pressure producing a coal derived syngas and a char residue.
Indirect coal liquefaction requires first gasifying the coal into a syngas.
Syngas is an intermediate feedstock for producing synthetically derived hydrocarbon products and fuels.
The syngas produced from gasification can vary depending on the feedstock and the gasification process involved.
