A novel process for the direct oxidation of hydrogen and hydrocarbons is disclosed, where the explosion risks inherent in gas phase oxidations are substantially eliminated. Gaseous oxidation reactants are soluble in a first reaction solvent phase such as a perfluorocarbon (e.g. C8F18) and the oxidation product is preferentially soluble in a second product solvent phase such as water or a dilute acid. A solid catalyst such as palladium on alumina is then contacted with the dissolved reactants. The oxidation product such as hydrogen peroxide may be separated from the reaction solvent phase by extraction into the immiscible product solvent phase and then separated from it by distillation, thereby allowing re-use of the aqueous phase. The present invention may be carried out using a two-phase reaction system whereby both the reaction solvent and product solvent are contained within a reaction vessel into which the solid catalyst is slurried and mechanically agitated to promote the reaction. |

Improved oxidation methods are provided wherein a reaction mixture comprising a substrate to be oxidized (e.g., phenols, alkenes) and an oxidation catalyst (typically dispersed in an organic solvent system) is supplemented with a compressed gas which expands the reaction mixture, thus accelerating the oxidation reaction. In preferred practice pressurized subcritical or supercritical carbon dioxide is used as the expanding gas, which is introduced into the reaction mixture together with an oxidizing agent. The inventive methods improve the substrate conversion and product selectivity by increasing the solubility of the oxidizing agent in the reaction mixture. |

In the reaction of catalytic gas phase oxidation induced by the supply of at least a raw material to be oxidized and a molecular oxygen-containing gas to a reactor for catalytic gas phase oxidation, a method for starting up the reactor for catalytic gas phase oxidation is disclosed which is characterized by causing the raw material and the molecular oxygen-containing gas to pass a range in which the concentration of the raw material is less than the lower explosion limit of the raw material and the concentration of oxygen is not less than the limiting oxygen concentration, but excluding the concentration of the raw material of 0 vol. %. The method enables the reactor to be started up economically and safely by avoiding the explosion range induced by the composition of a raw material and a molecular oxygen-containing gas supplied to the reactor and decreasing the amount of a diluting gas to be supplied. |

Petrochemicals are produced by the vapor phase reaction of a hydrocarbon with air in the presence of a suitable catalyst. The petrochemical product is removed from the product gas stream, and unreacted hydrocarbon in part or all of the remaining gas stream is recovered by subjecting the gas stream to a TSA process in which the adsorbed hydrocarbon is desorbed at elevated pressure by purging the adsorbent with hot compressed air, the air being heated by compression. The compressed air-desorbed hydrocarbon mixture is recycled to the reactor. |
