An Inorganic Process for Making Hydrogen Peroxide

Tokuyama Soda has disclosed a new process for making hydrogen peroxide by passing hydrogen and oxygen through an aqueous medium. No organic materials are required, but strong acids are used; thus problems are posed in selecting materials of construction. SRI has prepared a preliminary design for a continuous process using a fixed bed of palladium on kieselguhr. The new process appears to have lower capital costs and production costs than the established anthraquinone process. The advantages do not appear to be great enough to justify large-scale development at this time. However, there would appear to be distinct possibilities for lowered costs through further laboratory-scale development work on the new process.
