Abstract

La presente invención se refiere a un método para producir pentóxido de fósforo que incluye formar aglomerados de pre-alimentación que contienen partículas de mineral de fosfato, partículas de material carbonoso, y partículas de sílice y calentar los aglomerados de prealimentación en una atmósfera reductora o inerte a una temperatura de induración por encima de 900°C a menos de 1180°C y mantener la temperatura de induración durante 10 minutos o más. El método incluye formar aglomerados de alimentación y aumentar una resistencia a la compresión de los aglomerados de alimentación por encima de 25 lbf (111 N) usando el calentamiento, los aglomerados de alimentación exhiben una relación molar de calcio a 15 sílice menor de 1 y una relación molar de sílice a (calcio + magnesio) mayor de 2. Un lecho de horno de reducción se forma usando los aglomerados de alimentación, se genera gas de escape del horno, y el pentóxido de fósforo se recolecta del gas de escape del horno.
