Beschreibung
Zusammenfassung:	FIELD: chemical engineering. SUBSTANCE: method including charging ground solid into furnace, heating furnace, introducing fluidizing gas, and placing parts to be treated into fluidized-bed furnace, is distinguished by that material of fluidized bed is fine (0.4-1.0 mm) spherical alumina catalyst impregnated with nickel and magnesium oxides. EFFECT: increased productivity. 2 cl
