Abstract

A hydrogen peroxide and gluconic acid production method and system is disclosed that can include receiving an aqueous solution having glucose, water, and glucose oxidase at a reaction chamber. Here, the reaction chamber facilitates an enzymatic reaction between a gas phase and a liquid phase of the aqueous solution, thereby yielding a first solution comprising hydrogen peroxide, gluconic acid, and the glucose oxidase. The method can further include receiving the first solution at a separation chamber, wherein the separation chamber is comprised of a semi-permeable membrane having a pre-defined molecular weight barrier for separating the glucose oxidase, thereby resulting in a combined hydrogen peroxide and gluconic acid solution. The method can further include at least partially converting the gluconic acid into a gluconate salt, and separating and concentrating the hydrogen peroxide from the gluconic acid or gluconate salt via vacuum flash evaporation and vacuum distillation.
