Definitions

  • the method of coating is applicable to other form cokes, and produces a coated coke with superior properties.
  • the deposits are produced by introducing, into the hot gases which are used for calcining the briquettes, hydrocarbon vapors in addition to those coming out of the briquettes, in sufficient concentration so that a complete film is produced over the briquette surfaces.
  • concentration is rather higl1at least about volume percent of the gases. Lower concentrations may produce glanz carbon, but in such low amounts that the ultrafine pores are not completely filled.
  • Another advantage is that additional hydrocarbon vapors are produced for collection from the off-gases of the calciner. It is believed that the improvement in yield is due only partially to the introduction of the hydrocarbons in the coal, and that additional hydrocarbon is formed in the gas stream by reaction between free radicals formed in the presence of the hot calcining coke.
  • coal or char is devolatilized and, when recovered in the dust-collecting system, may be used in amounts up to 10% of the total particulate material, thus improving yields further.
