ABSTRACT:
For sterilizing surfaces with hydrogen peroxide, a stream of hot air is fed through a tube which includes a porous section, and vaporized hydrogen peroxide is diffused from the porous section into the hot air stream to obtain a combined hot air and vaporized stream mixture for supplying the vaporized hydrogen peroxide to a surface for sterilizing the surface. Further for carrying out the process, liquid hydrogen peroxide is fed to the porous section for forming a film on the porous section, and the porous section is heated to a temperature to vaporize the hydrogen peroxide for diffusion via the porous section into the hot air stream.
