Abstract:
A catalytic direct process for producing hydrogen peroxide (H2O2) product from hydrogen and oxygen-containing feedstreams, comprising the steps of:(a) providing a hydrogen-containing feed and oxygen-containing gaseous feed to a catalytic reactor; (b) providing a liquid mixture that includes at least some organic liquid solvent, said liquid mixture having a Solvent Selection Parameter (SSP) between 0.14Ã—10âˆ’4 and 5.0Ã—10âˆ’4; (c) providing a solid noble metal phase-controlled catalyst in said catalytic reactor; (d) contacting said hydrogen-containing and oxygen-containing feedstreams with said solid noble metal phase-controlled catalyst in the presence of said liquid mixture in said catalytic reactor at temperature of 0-100Â° C. and pressure of 100-3000 psig, for total residence time of 0.1 second to 5 hours, and forming an effluent stream containing gas and liquid fractions; (e) disengaging unreacted gases from the liquid fraction, which contains hydrogen peroxide; and (f) withdrawing a hydrogen peroxide-containing liquid product from the process.
