Abstract

"PROCESSO DE CONVERSãO PARA SìNTESE DE AMÈNIA, E, CONVERSOR PARA SìNTESE DE AMÈNIA". São divulgados um sistema conversor de amónia e método. O reator pode alterar a conversão a amónia controlando a temperatura de reação da reação exotérmica ao longo do comprimento do reator para que a mesma fique paralela à curva de equilíbrio do produto desejado. O reator 100 pode compreender um casco 101 e tubos internos com catalisador 109. A corrente de gás de alimentação entra no reator, flui através do casco 101 sendo aquecida por troca indireta de calor com os tubos com catalisador 109. Os tubos com catalisador 109 compreendem zonas reativas 122 que possuem catalisador e zonas limitadas de reação 124 que podem compreendem dispositivos inertes que funcionam tanto para separar as zonas reativas como para aumentar a área de transferência de calor e reduzir a temperatura da mistura de reação na medida em que o efluente passa através do tubo com catalisador 109.
