▎ 摘　　要

NOVELTY - Graphene type boron nitride series loaded phosphotungstic acid catalyst comprises graphene type boron nitride as carrier, high catalytic activity phosphotungstic acid loaded to graphene series type boron nitride, and reactive modifier; graphene type boron nitride is single or less layer boron nitride, layer number is less than 10. USE - The catalyst is used in the oxidation fuel comprising DBT module oil (preferred), 4,6-DMDBT model oil and BT module oil desulfurization (claimed). ADVANTAGE - The catalyst is white or faint yellow loose powder shape, without odor, insoluble in water and ethyl alcohol, do not cause pollution to environment, is stored in dry, and cool environment (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene type boron nitride series loaded phosphotungstic acid catalyst comprising adding phosphotungstic acid into anhydrous ethyl alcohol, magnetic stirring and dispersing at room temperature, adding graphene type boron nitride series, continuous stirring, dispersing, transferring mixes liquid into a reaction kettle for hydro-thermal reaction, moving mixed liquid into the oven for heat treatment, obtaining the high efficient catalyst.
