Coal can be converted into liquid fuel using several liquefaction processes which can be divided into two general egories. The first egory, indirect liquefaction, is a multistep procedure that first requires the gasifiion of coal to produce syngas. This process is shown schematically in Figure The syngas from the gasifier is converted to liquid fuel via two methods: the Fischer ...

What is "liquid coal"? – JeanMarc Jancovici

 · All included, turning coal to liquid becomes competitive for someone who buys coal on the international market (100 dollars per tonne), without capture and sequestration, when oil is over 100 dollars per barrel.. With coal priced 20 per tonne and cheap capital, it is possible to go down to 30 dollars per barrel of synthetic oil. If we add CO2 capture and sequestration, we get only 2 barrels ...

 · The primary benefit of coal is that it can be converted into a gaseous or liquid state and still deliver the same sort of energy and power. The conversion of coal helps this fuel to burn cleaner, limiting the production of ash and other byproducts that are created by the combustion. Fulltime Energy Source; Unlike solar or wind energy, the availability of coal energy is not bound by time or ...

 · By using Liquid Bridges carefully along with Liquid Valves when necessary, we can create pipe setups that can be used to automatically manage the state of liquids within that setup. This pattern is a component of many other build patterns; understanding it in isolation here will help with understanding the complexity that results when such loops are integrated with other build patterns.
