A process for catalytically directly producing hydrogen peroxide (H O ) product from hydrogen and oxygen-containing feeds by contacting them with a supported noble metal phase-controlled catalyst and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14&times;10 and 5.0&times;10 at reaction condition of 0-100&deg; C. temperature and 100-3,000 psig pressure. Unconverted feed gas and organic liquid solvent solution are usually recovered and recycled back to the reactor along with any recovered catalyst. If desired, the hydrogen peroxide product can be fed together with an organic chemical feedstock such as propylene and with the organic liquid solvent solution into a second catalytic reaction step which oxidizes the feedstock to produce a desired crude oxidized organic product such as propylene oxide, which may be purified by distillation steps and recovered from the solvent solution.

Catalytic direct production of hydrogen peroxide from hydrogen and oxygen feeds

A highly dispersed iron-based ionic liquid or liquid-gel catalyst which may be anion-modified and metals-promoted has high catalytic activity, and is useful for hydrocracking/hydrogenation reactions for carbonaceous feed materials. The catalyst is produced by aqueous precipitation from saturated iron salt solutions such as ferric sulfate and ferric alum, and may be modified during preparation with anionic sulfate (SO.sub.4.sup.2-) and promoted with small percentages of at least one active metal such as cobalt, molybdenum, palladium, platinum, nickel, or tungsten or mixtures thereof. The resulting catalyst may be used in a preferred ionic liquid form or in a liquid-gel form, and either fluidic form can be easily mixed and reacted with carbonaceous feed materials such as coal, heavy petroleum fractions, mixed plastic waste, or mixtures thereof. The invention includes methods for making the ionic liquid or liquid-gel catalyst, and processes for using the fluidic catalysts for hydroprocessing the carbonaceous feed materials to produce desirable low-boiling hydrocarbon liquid products.
