Technical, Energetics, and Economic Comparison of NRL Oxidative Coal Liquefaction Process with some Developed Coal Liquefaction Processes.

Abstract : An oxidative process for the liquefaction of coal is being studied at NRL. This process offers the technical advantage of using a very common reactant, air, compared to the currently favored reductive processes (H-Coal, SRC, and EDS) which require hydrogen as the reactant. The NRL process has the additional engineering advantage of operating at much lower pressures and somewhat lower temperatures than the reductive processes. The product from the NRL process is expected to have a heating value similar to that from the SRC process. (Author)
