Abstract
Un proceso para la recuperación de azufre de una corriente de gas que contiene SO2 a través de la conversión catalítica de la misma a azufreelemental, que comprende la conversión de SO2 y H2S en presencia de azufre líquido y un sistemacat alizador a base de un catalizador heterogéneo quecataliza la reacción Claus, mientras que como promotor para la reacción Claus se encuentra presente un compuesto de nitrógeno básico en el azufre líquido.A process for the recovery of sulfur from a gas stream containing SO2 through its catalytic conversion to elemental sulfur, which comprises the conversion of SO2 and H2S in the presence of liquid sulfur and a catalyst system based on a heterogeneous catalyst It catalyzes the Claus reaction, while a basic nitrogen compound is present in liquid sulfur as a promoter for the Claus reaction.
