Hydroprocessing of low temperature coal tar (LTCT) for the production of clean fuel was investigated over fluorinated NiW/Al2O3-SiO2 catalyst in a fixed bed reactor. Experimental study on the coal tar hydrocracking process in supercritical solvents Article in Fuel 91(1)–39 January with 83 Reads How we measure 'reads'.

Figure 2 Flow sheet of low-temperature coal tar hydrocracking in supercritical gasoline flow H-OUT should be high enough to transform the liquid phase into vapor only, or otherwise some compli-cations would occur[9].

Then the liquid was fed into the rectification tower by COMP. Four product streams can. Ethane, phenols, cresols, and BTX from coal, lignite, or peat using HYFLEX technology. Low-temperature lignite pitch was thermally cracked in a 4-inch id reactor at 1, deg to 1, deg f.

and pitch feed rates of, and Pounds per hour to produce coke, oil, and gas. Temperature had a much greater influence on product yields than pitch feed rate.

International Conference on Coal Science Proceedings The chapter describes a study that observed the kinetics of drying of bed-moist samples of four North Dakota lignites. The samples were ground to less than 74 μm particle size, and mass loss rates were measured in zero relative humidity environment at a constant or K.

Tar yields from low-temperature carbonization correlate with the amount of crypto-eugelinite in samples selected to represent petrographically distinct coal facies of the Wyodak-Anderson coal zone.

Tar yields from Fischer Assay range from. approach of linear viscoelastic materials. Current test methods to address low temperature cracking, such as the Bending Beam Rheometer (BBR) (1), characterize the material in the linear viscoelastic domain at small strain levels and, therefore, do not provide the complete picture for thermal cracking characterization.
