Abstract:
Thanks to cclic utilization of resources, steel-chemical co-production proiects have become the industrial focus with remarkable economic , environmental and soca teneits. Among these proects a key technoiogy is the acep puriication of converter gas, in ight of the charac teristics of the components of converter gas,the hydrolysis mechanism of carbonyl sulfur and the removal mechanism of oxygen in the converte gas have been studied ,and the technology sutable for removal of carbonyl sulfur as wel asthe other sulfides in the converter gas has been deveroped,together with the composite oxide catalyst for oxygen removal. The operation results show that the total sulfur content of the purified converter gas can be <0.1mg/m³and its oxygen content can reach <30mg/m³’,which meets the requrements of chemical production and booststhe promotion speed of colaborative carbon reduction technology in stee-chemical co-production,and thus enjoys a good industrial application prospect.
