The LFC technology uses a mild pyrolysis or mild gasification process to produce a low-sulfur, high-heating value fuel and a coal-derived liquid [37–39, 43]. In the process, coal that has undergone some coal drying is fed into a pyrolyzer that is operated near 1,000°F to remove any remaining moisture and release volatile gases.

Coal gasification technologies have been known for more than 100 years. Gasification is a thermochemical process in which the fuel, coal in this case, is converted into synthesis gas composed of carbon monoxide and hydrogen. There are number of papers deal with the lignite co-gasification with biomass/biowaste or Solid Recovered Fuel.

Gasification is a process in which a solid fuel, like coal, is reacted at high temperatures (593–1260°C [1100–2300°F]), generally in the presence of limited O2 and/or steam. The primary gaseous products are H2 and carbon monoxide (CO), with water (H2O) and carbon dioxide (CO2) as substantial byproducts.

The basic processing units in a coal-based ammonia plant are the ASU for the separation of O 2 and N 2 from air, the gasifier, the sour gas shift (SGS) unit, the acid gas removal unit (AGRU), and the ammonia synthesis unit. Oxygen from the ASU is fed to the gasifier to convert coal into synthesis gas (H 2, CO, CO 2) and CH 4. There are many ...

Synthetic natural gas (SNG) is one of the commodities that can be produced from coal-derived syngas through the methanation process. The economic viability of producing SNG through coal gasification is heavily dependent on the market prices of natural gas and the coal feedstock to be used, the value of by-products such as carbon dioxide (CO 2) …

Advanced Coal Technologies. In the nationwide effort to reduce emissions of carbon dioxide (CO2) and other pollutants when fossil fuels are burned, coal is a prime target: It accounts for more than one-quarter of America's CO2 emissions. And although coal's share of all fuels used for electrical generation is expected to decline during the next 25 years, …

The resource endowment structure of being coal-rich and oil-poor makes China's production of coal-based ammonia and urea, with a low production cost and a good market, a competitive advantage.
