Exxon Donor Solvent Coal Liquefaction ProcessTraduire cette page

    Coal Feed Flexibility[6][6a] Lab-scale work by Exxon has shown that the EDS process is suitable for coals of different rank. Figure 3 shows that bitu- minous, sub-bituminous, and lignite rank coals can all be lique- fied using the EDS process. This figure also shows that the C3-1000°F yields for the various coals correlate with coal rank. One way to increase C3-1000°F liquid yields is to ...

    Another advanced coal technology is coal gasification, a process in which coal is converted to a gas (called syngas) before it is burned, making it easier to separate CO2 as a relatively pure gas before power is generated. Alternatively, it is possible to burn coal in oxygen instead of air (as is currently done) in order to reduce the amount of flue gas—essentially exhaust—that must be ...
