Abstract
Various systems, devices, NO2 absorbents, NO2 scavengers and NO2 recuperator for generating nitric oxide are disclosed herein. According to one embodiment, an apparatus for converting nitrogen dioxide to nitric oxide can include a receptacle including an inlet, an outlet, a surface-active material coated with an aqueous solution of ascorbic acid and an absorbent wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the surface-active material and the absorbent such that nitrogen dioxide in the gas flow is converted to nitric oxide.
Claims16
An apparatus for converting nitrogen dioxide to nitric oxide comprising
- a receptacle including an inlet, an outlet, a surface-active material coated with an aqueous solution of ascorbic acid and an absorbent,
- wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the surface-active material and the absorbent such that nitrogen dioxide in the gas flow is converted to nitric oxide;
- wherein the apparatus further comprises a NO2 scavenger selected from the group consisting of proline and diphenylamine.
A recuperator for converting nitrogen dioxide into nitric oxide comprising:
- an exit shell including an outlet;
- an inside shell wherein the inside shell includes perforated inner and outer tubes with fixed annulus;
- a surface-active material coated with an aqueous solution of ascorbic acid and an adsorbent;
- a top cap including an inlet wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the surface-active material such that nitrogen dioxide in the gas flow is converted to nitric oxide;
- and a NO2 scavenger selected from the group consisting of proline and diphenylamine.
