Plasma Reactor for On-Site Hydrogen Peroxide Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing hydrogen peroxide and nitrogen oxides in agriculture require additional chemical intermediates and stabilizers, and there is a need for a system that can simultaneously produce these compounds from air and water without such requirements.
Innovation Solution
A plasma reactor system that uses air and water to generate hydrogen peroxide and nitrogen oxides by injecting a mixture of liquid water and gas into electrically-conductive capillaries, propagating a plasma discharge to dissociate water and form these compounds, which are then dissolved and protected within a flowing liquid film, allowing for on-site production and variation of concentrations through reactant flow rates.

Engineering Contradiction Analysis
1Quantity of substance
If conventional methods are used to produce hydrogen peroxide and nitrogen oxides, then the products can be obtained, but additional chemical intermediates and stabilizers are required
Solution Approach 1:
The plasma reactor system uses only air and water as feedstocks to produce hydrogen peroxide and nitrogen oxides directly, eliminating the need for additional chemical intermediates and stabilizers. The system serves itself by converting readily available substances (air and water) into the desired products through plasma discharge, making the process simpler and more sustainable.
2Ease of operation
If hydrogen peroxide and nitrogen oxides are produced using conventional methods, then the products are available, but they require stabilizers and cannot be produced on-site
Solution Approach 1:
The invention extracts and eliminates the requirement for stabilizers and complex chemical handling systems by using plasma discharge to directly convert air and water into hydrogen peroxide and nitrogen oxides. This extraction of unnecessary chemical components enables on-site production without the complexity of stabilizer management and chemical storage.
3Productivity
If additional chemicals and stabilizers are used in production, then the chemical reactions can proceed, but the system becomes less environmentally friendly
Solution Approach 1:
The plasma reactor creates a controlled environment where air and water are directly converted into products without requiring additional chemical intermediates. This inert-like environment (using only air and water) eliminates harmful chemical byproducts and reduces environmental impact while maintaining productive output of hydrogen peroxide and nitrogen oxides.
