Abstract
Description
technical field
[0001] The present invention relates to a desulfurizer and its application, more specifically, the present invention relates to a normal temperature iron oxide desulfurizer and its application. Background technique
[0002] As we all know, desulfurization is an important process link in the purification of raw gas in many chemical productions. Many chemical companies have adjusted their raw material routes to continuously develop new products to meet market competition and pursue the best economic benefits. However, various sulfur components exist in many raw materials, such as inorganic sulfur such as hydrogen sulfide, organic sulfur such as carbonyl sulfide, carbon disulfide. Therefore, the desulfurization process is required to maintain extremely high desulfurization efficiency, gas purification, wide application range, convenient use, low cost, safety and harmlessness.
[0003] Generally, the raw material gas is wet desulfurized first, and after the raw...
