Abstract
1311100 Furnaces for treating materials in suspension HALDOR FREDERIK AXEL TOPSOE 10 Aug 1970 [15 Aug 1969] 40924/69 Heading F4B [Also in Division C1] A reactor for electrically heating freely falling particulate material comprises a carbon reaction tube 1, a ceramic lining 3, a layer 4 of charcoal insulation and a steel shell 2, terminals 6 making contact with the tube through a metal cylinder 7 and a carbon block 9 respectively and a product collector 11 at the bottom of the apparatus. A graphite feed tube 10, gaseous supply and removal pipes 12 and 13 and access ports 5 are also supplied. Within the carbon reaction tube neutral or reducing conditions are maintained. Where the product collects in a molten state the discharge apparatus shown in Fig. 2 may be used. It comprises a crucible 22 with a discharge opening enclosing another crucible 26 shaped as shown to collect a pool 30 of molten material draining from a cover 28. The pool 30 discharges through an outlet 27 and a tube 23. All the parts are made of graphite and are heated by current supplied through the terminal 6. For the production of phosphorus, the charge material comprises phosphate rock, silica and carbon which latter may be deposited in the phosphate rock particles by cracking hydrocarbons. The reactor may also be used for burning clays and cement, for the production of spherical particles of refractories and metals, for the production of carbides stainless, steel and ferro-alloys by reaction of oxides or elements with carbon and the production of volatile chlorides by reaction between oxides and calcium chloride.
