Abstract
Process and apparatus for the thermal treatment of pulverulent substances, in which the pulverulent substance is dispersed in a carrier gas and is passed in a continuous manner through a heated reactor where it is thermally treated and is then quenched by a cooling medium and is collected in a gas-solids separating unit.
Claims15
A process for the thermal treatment of pulverulent substances comprising dispersing the pulverulent substances in a first carrier gas forming a gas-solids mixture and conveying the dispersed pulverulent substances by means of a second carrier gas in a continuous manner through a heated reactor under treatment conditions, then quenching with a cooling medium and collecting the thermal treated pulverulent substances in a gas-solids separating unit, wherein the first and second carrier gas each is independently selected from the group consisting of nitrogen, argon, helium, hydrogen, carbon dioxide, carbon monoxide and mixtures thereof, and the pulverulent substances are selected from the group consisting of carbon blacks, activated charcoals, graphites, fiber-shaped graphitic nanotubes, supported catalysts, metal containing supported catalysts, supported catalyst precursors, metal containing supported catalyst precursors and mixtures thereof.
