Hydrogen Peroxide Production Continuously, Low Cost Energy Efficient

quick detail

During the last four or five years the increasing use of hydrogen peroxide, not only in bleaching and the manufacture of other per-compounds, but also as a propellant and as a reagent in organic synthesis, has resulted in a great deal of work being carried out on alternative methods of manufacture to the electrolytic processes developed over the last fifty years. Of these alternatives, that which has received the most attention has been the use of organic intermediates, particularly sub- stituted anthraquinols, which autoxidise to form hydrogen peroxide.

And this is exactly what Ally Hi-Tech uses for hydrogen peroxide production.

Process Schematic:

Process

In the presence of Pd catalyst, the alkyl anthraquinone dissolved in the organic solvent is hydrogenated to produce the alkyl anthra-hydroquinone, which is oxidized to get the hydrogen peroxide under given reaction conditions eventually. Meanwhile the alkyl anthra-hydroquinone is converted into alkyl anthraquinone and the stream of working solution contained H2O2. The resulting stream of working solution is fed to the extraction column for extraction by using deminaralized water as extracting agent in a counter-current flow to produce H2O2, which is purified to form the finished product-H2O2 and it will be delivered to the storage tank. The solution of alkyl anthraquinone after treatment returns to the hydrogenation section for reuse.
