Title: Improvements in or relating to the production of phosphorus and phosphorus-oxygen compounds from raw phosphates
IPC: C01B25/02
Filed: 1930-06-04
Abstract: In the production of phosphorus or phosphorus-oxygen compounds by treating phosphates in a shaft furnace, the phosphate is used in the form of previously sintered pieces, with the requisite quantity of coke and of silica or silicates if necessary.  A suitable sintering may be effected by heating the phosphate with 6-10 per cent of coke dust in a Dwight-Lloyd sintering apparatus. The shaft-furnace charge may be covered with a carbon-containing layer in dust or grains. Preferably the sintered phosphate while still hot is treated with a mixture of coke dust and water which may contain organic or inorganic constituents such as molasses residues to promote the adhesion of the coke to the phosphate; the quantity of liquid is such as to be vaporized by the heat of the mass, and the quantity of the coke dust such as to leave the phosphate sufficiently porous.  The shaft furnace is preferably charged with alternate layers of phosphate and coke, and the blast is preferably preheated to 700-800 DEG  C. or over.  If desired a part of the coke may be dispensed with, and an auxiliary oil heater placed at the lower part of the furnace, the gases from the combustion of the oil assisting in flushing the shaft. Preferably the shaft is comparatively high, for instance 6 or 7 times the diameter, and the lower walls may be water-cooled.
