The HiChlor process for recovery of metals from power plant fly ash and other coal-conversion solid wastes is described. Results are presented for the production of volatile metal chlorides from fly ash by carbochlorination with phosgene. Data are included for reaction rates measured gravimetrically for temperatures of 450 to 800/sup 0/C and phosgene partial pressures of 10 to 100 kPa, and for chemisorption and B.E.T. isotherms used to determine active and total surface areas as a function of fly-ash conversion. Implications in terms of HiChlor reactor design are discussed.
