103 Intrinsically safe oxidation process US09882519 2001-06-15 US06768013B1 2004-07-27 Peter R. Pujado
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.

105 Catalytic oxidation of organic substrates by transition metal complexes in organic solvent media expanded by supercritical or subcritical carbon dioxide US10205863 2002-07-26 US20030100805A1 2003-05-29 Bala Subramaniam; Daryle H. Busch; Ghezai T. Musie; Ming Wei
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.

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.
