Small Business Innovation Research
INNOVATION The innovation consists of a device
that allows the production of an aqueous solution
of hydrogen peroxide (H2O2) using only oxygen,
water, and electrical power. Heterogeneous
catalysts have been developed that efficiently
utilize the H2O2 to oxidize a wide range of
aqueous phase organic contaminants at low
temperatures.
COMMERCIALIZATION The technology has significant
potential in the field of environmental
remediation and commercial H2O2 production.
Calgon Carbon Corporation has expressed a desire
to assist in further development of the
technology and licensing it for commercial
applications. Solvay Interox, Inc., the worlds
largest producer of hydrogen peroxide, has also
expressed a desire to assist in development.

• ACCOMPLISHMENTS
• H2O2 is formed within a pure water stream,
  simplifying production and eliminating
  undesirable by-products.
• The system is capable of oxidizing higher organic
  contaminant loads containing more refractory
  organic species at lower temperatures than
  previous APCOS processes. It will lower energy
  consumption and the need for ancillary water
  treatment processes.
• A 0.5 g/L acetic acid solution processed through
  a prototype catalytic reactor system achieved a
  96.1 reduction in total organic carbon at a flow
  rate of 10 mL/min at 90C, representing a major
  advancement in the state of the art for APCOS
  systems.
• The use of H2O2 results in sterile reactor
  effluents produced at much lower temperatures
  than is achievable by conventional means.

GOVERNMENT/SCIENCE APPLICATIONS The H2O2 APCOS
technology is uniquely suited to Advanced Life
Support Systems (ALSS). It provides
significantly enhanced water reclamation
capabilities over existing oxidation processes in
a smaller size package that weighs less and uses
less power. The in-line, on-demand production of
H2O2 has the added benefit of sterilizing process
water at much lower temperatures than existing
technology and provides a ready supply of safe
sterilant for use in surface sterilization and
decontamination. The prototype reactor and H2O2
generator delivered to NASA Ames Research Center
provide an excellent test bed for further ALSS
development. Picture is not available.
