n the process of steel production, a large number of blast furnace gas, converter gas, coke oven gas, rich in carbon monoxide, hydrogen and methane are valuable components, which are the main secondary energy sources of steel works. 55-60% of H2 is contained in coke oven gas, converter gas and blast furnace gas respectively

In industrial production, such as steel industry, petroleum and chemical industry, mass of CO, as "waste", was not good used, for example: blast furnace gas, converter gas, yellow phosphorus tail gas, chemical tail gas, calcium carbide tail gas, garbage incineration gas, etc. Above gases are all rich in CO gas, can be used as secondary energy. PKU PIONEER developed a new VPSA-CO separation and purification technology. The new technology can recovery CO from secondary energy, and used it as chemical raw materials. By this way, it can greatly reduce CO2 emissions, save fossil energy, has good economic and social benefits.

Using the independently-developed and high-efficiency PSA-H2 adsorbent, PIONEER's rapid, low consumption and high-efficiency PSA-H2 process has the following features, low investment and operating cost, high purity and recovery of gas product, flexibility of feed gas and easy load regulation.

The content of CO in the yellow phosphorus tail gas reaches up to 90%. Yellow phosphorus tails gas belongs to the ore smelting tail gas whose components are complicated and impurities are various. The existence of phosphorus and sulfur in the tail gas utilization may corrode the equipment and shorten the life of the catalyst, so the utilization rate is quite low.
