The invention discloses a pure oxygen combustion and carbon dioxide capturing system of a heating furnace. The system comprises a liquid oxygen storage slot (1), a vaporizer (2), the heating furnace (5), a waste heat recycling device and a carbon dioxide recycling device; liquid oxygen from the liquid oxygen storage slot (1) is in heat exchange with a refrigerant in the vaporizer (2), and generated oxygen is conveyed into the heating furnace (5); high-calorific-value fuel gas in the heating furnace and the oxygen from the vaporizer (2) are combusted in a pure oxygen combustor (4), and generated smoke gas is exhausted into a heating furnace flue; the waste heat recycling device is arranged in the heating furnace flue and used for recycling heat in the smoke gas; the carbon oxide recycling device is arranged in the heating furnace flue; and the low-temperature refrigerant output by the vaporizer (2) is utilized to cool the smoke gas to recycle carbon dioxide in the smoke gas. The invention further discloses a pure oxygen combustion and carbon dioxide capturing process of the heating furnace. According to the pure oxygen combustion and carbon dioxide capturing system and process of the heating furnace, noise pollution of a combustion fan is reduced, and reducing emission of NOx is realized, so that CO2 capturing cost is greatly reduced.

A catalyst containment unit, includes two concentric perforate members defining an annular space in which a particulate catalyst may be placed, and process fluid-impermeable end members mounted on the ends of the perforate members, wherein one end member extends across the unit to provide a closed end and the other end member closes the annular space thereby providing an open end through which gases may enter or exit the unit, and suspending means attached to one or both end members for securing the unit within an ammonia oxidation vessel. The unit may be suspended, for example, below a precious metal ammonia oxidation gauze pack and may contain a particulate ammonia oxidation catalyst or nitrous oxide abatement catalyst. A catalyst combination includes a precious metal ammonia oxidation catalyst gauze on a supporting framework and a particulate catalyst disposed in a catalyst containment unit.
