The majority of the coal liquefaction processes involve the addition of a coal-derived solvent prior to heating the coal to the desired process temperature. This is, essentially, a means of facilitating the transfer of the coal to a high-pressure region (usually the reactor) and also to dimini...
The method includes the steps as follows: (1) adding smashed direct coal liquefaction residue together with KNO3, KOH and absolute alcohol into water, stirring to be uniform under room temperature, and later drying the obtained mixture to obtain a dry material; (2) placing the prepared dry ...
As a main byproduct of direct coal liquefaction process, direct coal liquefaction residue (DCLR) should be disposed and utilized rea- sonably. The direct coal liquefaction plants tend to gasify DCLR to supply hydrogen needed in the liquefaction process, which can realize self-sufficiency in ...
The effect of small molecular compounds in coal on quick direct coal liquefaction at high temperature was studied. The results showed that extraction with tetrahydrofuran just removed a portion of organic compounds, which were free or embedded in the macromolecular network structure in coal, without ...
