After pulverizing to minus 200 mesh, a mixture of coal and pyrite particles is passed through an A.C. silent corona discharge in the presence of a reactant gas. Simultaneously, the particles are de-agglomerated and an electrical or magnetic difference between them is enhanced. Thereafter, the pyrite ...

A moving fluid containing pollutants including NOx compounds is subjected to a relatively low-power alternating-current dielectric discharge for a relatively long time duration. In this manner, pollutants are oxidized and dissociated while the temperature of the fluid is kept low enough to prevent t ...

Stanley R Rich: Method of treating coal for increasing the availability of coal-fired boilers. Advanced Energy Dynamics, Wolf Greenfield & Sacks, October 9, 1984: US04475922 (4 worldwide citation)

After pulverizing feed coal to a range of particle sizes from 1 to 250 microns, the particles are divided at approximately a micron level in the range from 37 to 74 microns into a coarse fraction and a fine fraction. The inorganic material is separated from the organic material, at least in the coar ...
