Abstract
Inventia descrie un procedeu de obtinere a catalizatorului de conversie a oxidului de carbon la temperatura înalta cu continut redus de sulf. Procedeul consta în obtinerea oxidului de fier din sulfat de fier din sulfat de fier în urma reactiei acestuia cu hidroxidul de amoniu si carbonat de amoniu apoi calcinarea carbonatului obtinut. îndepartarea sulfului ramas în pulpa de carbonat de fier se face prin dizolvarea acestuia în acid azotic diluat si precipitarea sulfului din solutia cu azotat de calciu sau carbonat de calciu apoi filtrarea sulfatului obtinut. Din filtrat se reprecipita fierul sub forma de carbonat cu hidroxid de amoniu si carbonat de amoniu.
