Description
Hydrogen produced from coke oven gas is a clean energy source, primarily used as a chemical feedstock, in fuel cells, and in certain specific industrial processes. This dataset is formed by merging data from multiple sources. The coke oven gas-based hydrogen production technology extracts hydrogen from coke oven gas generated during the coking process. The compressed and purified coke oven gas undergoes a pressure swing adsorption process to remove all impurities except oxygen, followed by catalytic reactions to remove oxygen, and finally dried to obtain the purified hydrogen product.
Activity Description
Hydrogen production from coke oven gas involves separating hydrogen from the gas, typically using pressure swing adsorption (PSA) or membrane separation technologies, covering energy consumption, by-product treatment, waste emissions, and equipment maintenance throughout the entire process.
Process Description
Hydrogen produced from coke oven gas is a clean energy source, primarily used as a chemical feedstock, in fuel cells, and in certain specific industrial processes. Compared with other hydrogen production methods, hydrogen production from coke oven gas utilizes existing gas resources in steel plants, reducing dependence on external hydrogen sources. At the same time, this method also helps reduce emissions from steel plants and enables resource recycling.
