Method and apparatus for the production of nitric oxide gas mixture |
December 2, 1997 |
| A therapeutic oxygen-nitric oxide gas mixture is produced by passing air, oxygen-enriched air or air containing a small amount of ammonia over a noble metal catalyst at an elevated temperature. The product gas containing nitric oxide and a small amount of nitrogen dioxide is passed t |

Process for the manufacture of nitric oxide |
September 23, 1997 |
| Nitric oxide is produced by reacting aqueous nitric acid with gaseous sulfur dioxide in a gas-liquid contact reactor. The reaction is conducted in the presence of a stoichiometric excess of nitric acid to minimize the production of byproduct nitrous oxide and nitrogen. The nitric oxide |

Process for the purification of nitric oxide |
September 23, 1997 |
| A gas mixture comprised of nitric oxide and, optionally an inert gas, and containing small amounts of nitrogen dioxide, and perhaps moisture and sulfur dioxide, is purified by passing the gas stream through a bed of zeolite having a silica to alumina ratio not greater than about 200. The |

Process for the purification of nitric oxide |
May 7, 1996 |
| A gas mixture comprised of nitric oxide and, optionally an inert gas, and containing small amounts of nitrogen dioxide, and perhaps moisture and sulfur dioxide, is purified by passing the gas stream through a bed of metal cation-free silica, alumina, or zeolite. The concentration of |

Process for the purification of nitric oxide |
May 23, 1995 |
| A gas mixture comprised of nitric oxide and, optionally an inert gas, and containing small amounts of nitrogen dioxide, and perhaps moisture and sulfur dioxide, is purified by passing the gas stream through a bed of metal cation-free alumina-deficient zeolites of types Y or ZSM-5. The |

Process for the production of petrochemicals |
November 16, 1993 |
| Petrochemicals are produced by the vapor phase reaction of a hydrocarbon with substantially pure oxygen in the presence of a suitable catalyst. In the improved process, the principal product is removed, carbon monoxide, present in the reactor effluent as a byproduct, is oxidized to carbo |

Process for the production of anhydrides |
June 30, 1992 |
| This invention provides a process for the production of an anhydride by the vapor phase reaction of a hydrocarbon with substantially pure oxygen in the presence of a suitable catalyst. In the improved process, the anhydride product is removed, carbon monoxide, present in the reactor |
