Description

technical field [0001] The invention relates to the technical field of sulfur-resistant conversion, in particular to a sulfur-resistant conversion reaction equipment and a sulfur-resistant conversion process method. Background technique [0002] The CO shift process refers to the raw material gas (including CO, H 2 S, etc.) and water vapor on the catalyst for CO shift reaction to produce hydrogen and carbon dioxide to obtain synthesis gas that meets the requirements. [0003] Raw gas obtained from coal gasification usually has high CO concentration (40-75% by volume), high steam-gas ratio (1.0-1.8 ratio of dry raw gas to water vapor), H 2 S concentrated height (5-15g / Nm 3 ), high pressure (3.0-8.0MPa), etc., and there are also oil and dust. To realize the efficient shift hydrogen production of these complex mixed gases, the sulfur-resistant shift process is usually adopted, that is, the complex mixed gas after gasification is directly shifted without desulfurization.
