Country of origin: United Kingdom

Summary

A UK manufacturer of filter products is searching for novel reactions or materials to selectively remove CO from exhaust streams, which could be used in a range from personal to industrial filters. Existing technologies are too sensitive to environmental factors. The company has resources for further technical development and commercialisation on a global basis. The nature of the agreement will depend on the stage of development.

Full description

Carbon monoxide (CO) is a highly poisonous, colourless and odourless gas produced as a result of incomplete burning of carbon-containing fuels in combustion processes. It can occur in a number of industrial and domestic settings including: chemical manufacturing processes; furnaces, kilns and foundries; exhaust gas of internal combustion engines, motor vehicles and fuel cell vehicles; domestic space and combustion heaters; and smoke.

A UK company is searching for an innovative technology to selectively remove/filter CO from exhaust streams that
- works in polluted environment;
- is stable until use;
- can be made compact enough for use in personal respirators.

Carbon monoxide is one of a number of combustion gases and therefore solutions to reduce this have to be able to work in the presence of a wide range of other gases and particulates  i.e. not a clean environment.

Whilst there are a number of technologies that can remove carbon monoxide under certain conditions (such as adsorption and catalysis), there are a number of environmental factors that affect the performance. Potential solutions to address these factors could be found amongst the following materials and processes:
" Emission control catalysts
" Adsorption
" Oxidation catalysts to convert carbon monoxide to carbon dioxide
" Metals and metal oxides such as gold, palladium, platinum, titania, alumina, ceria, zirconia, iron oxide, zinc oxide and magnesium oxide
" Nanoparticle based catalysts
" Process to encapsulate reactive particles
" Encapsulated liquids with permeable shell/membrane
" Increase stability of oxidising agents (i.e. Hopcalite  copper manganese oxide - in presence of water vapour
" Chemical additives for membranes

Technical Specifications / Specific technical requirements:
" High selectivity towards CO
" Stable during storage  active only in presence of CO
" Maintain performance under high flow rate (fast kinetics)  1 litre/min
" Able to function at room temperature
" Non-toxic/no toxic by-products
" Low cost
" Ideally in granular form, but could be powder/liquid
" Compact  either in film, membrane or paper format or dense foam/granules
" Ability to work in complex environment (in the presence of other gases and particulates)

Partner expertise sought:

- Type of partner sought: industry, academia
- Specific area of activity of the partner: research into adsorption and catalysis
- Task to be performed by the partner sought: potential solutions may be licensed, developed further jointly or acquired under a commercial agreement. Interested parties are invited to provide a short non-confidential description on the technical and marketing advantages and initial suggestions on possible methods of co-operation.
