There are several methods for Hydrogen Peroxide Plant, among them the AO(auto-oxidation) process is the most prevailing one. In this process, 2-alkyl anthraquinone is mixed with organic solvent to make up the working solution, which is hydrogenated in presence of catalyst, and the resulting is oxidized by air (or oxygen) in counter-current way before being extracted, regenrated, purified and enriched to get commercial hydrogen peroxideproduct. Depending upon the different reactor type in the hydrogenation unit, AO process is further divided into Fixed Bed Reactor Process and Fluidized Bed Reactor Process. SL Tec provides both processes.

For this hydrogen peroxide production technology, SL TEC cooperates with one of the branch companies of China National Chemical Engineering Co., Ltd.------ SEDIN Ningbo Engineering Co., Ltd. to offer a turnkey hydrogen peroxide plant.

The Fluidized Bed Reactor Process SL TEC offers uses heavy aromatics-TBU binary solvent in the working solution(WS) system, with the WS capacity (H2O2-kg/m3-WS) reaching 12g/L.
