Abstract

UN OXIDO METALICO SE REDUCE CARBOTERMICAMENTE A SU POLVO DE NITRURO METALICO O DE CARBURO METALICO EN UN REACTOR DE FLUJO DE GRAVEDAD VERTICAL (119 A BASE DE AÑADIR DIRECTAMENTE EN UNA ZONA DE REACCION (31), QUE SE ENCUENTRA DENTRO DE UN REACTOR, PERLAS PRECURSORAS QUE CONTENGAN OXIDO METALICO, UN MATERIAL AGLUTINANTE TERMICAMENTE DESCOMPUESTO Y CARBONO O UNA FUENTE DE CARBONO. LAS PERLAS FORMAN UN LECHO DE PERLAS (19). LA PARTE SUPERIOR DEL LECHO (18) SE DEBE MANTENER DENTRO DE LA ZONA DE REACCION CALENTADA. EL MATERIAL AGLUTINANTE ES UNA MEZCLA DE ALMIDONES DE TRIGO Y MAIZ. EL MATERIAL AGLUTINANTE SE DESCOMPONE TERMICAMENTE EN UN RESIDUO CARBONOSO QUE FUNCIONA COMO FUENTE ADICIONAL DE CARBONO Y COMO AGLUTINANTE DE LAS PERLAS PRECURSORAS.
