Mineral Composition for CO2 and NOx Gas Mineralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing atmospheric CO2 and NOx levels, such as photocatalytic paints and CO2-absorbing cements, either increase CO2 levels as by-products or are economically non-viable, and existing technologies fail to effectively mineralize these gases, leading to persistent environmental and health issues.
Innovation Solution
A mineral composition comprising magnesium, iron, calcium monoxide, silicon dioxide, and titanium (IV) oxide, used in paints, dyes, and natural rubber/gum products, which absorbs and adsorbs CO2 and NOx through carbonation and nitrification processes, converting them into a harmless white calcareous powder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If photocatalytic paints are used to reduce NOx levels, then NOx removal is improved, but CO2 levels increase as by-products
Solution Approach 1:
The patent converts the harmful CO2 by-product generated during NOx photocatalysis into a beneficial carbonate mineral. The titanium dioxide catalyst converts NOx to CO2, and the magnesium oxide then reacts with this CO2 to form stable carbonate minerals, effectively transforming the harmful by-product into a useful sequestration mechanism.
Solution Approach 2:
Magnesium oxide acts as an intermediary substance that mediates between the CO2 produced by photocatalysis and the final carbonate mineral product. It captures the CO2 and transforms it into stable carbonate compounds, preventing CO2 release while completing the NOx removal process.
2Object-affected harmful factors
If CO2-absorbing cements are used, then CO2 removal is improved, but economic viability deteriorates
Solution Approach 1:
The patent creates a multi-functional paint system that simultaneously removes both CO2 and NOx, whereas traditional solutions only targeted one gas. This dual functionality increases the value proposition and economic viability by addressing multiple pollution problems with a single application.
Solution Approach 2:
The invention uses a composite material system combining titanium dioxide (for photocatalysis) and magnesium oxide (for CO2 absorption) within a paint matrix. This composite approach enables both NOx and CO2 removal mechanisms to work together, creating an economically viable solution that delivers multiple environmental benefits.
3Quantity of substance
If existing mineralization technologies are used, then gas capture is improved, but effectiveness in mineralization deteriorates
Solution Approach 1:
The patent changes the chemical parameters by using magnesium oxide instead of traditional calcium-based absorbents. This parameter change enables more effective mineralization through the formation of stable magnesium carbonate minerals, improving both the capture efficiency and the reliability of long-term sequestration.

AI summary
The invention relates to a composition for mineralising carbon dioxide and nitrogen oxide gases, which comprises a mixture of magnesium (between 1 and 25%), iron (between 1 and 23%), calcium monoxide (between 1 and 25%), titanium dioxide (between 0.1 and 11%) and silicon dioxide (between 16 and 75%), with a particle diameter between 100 nm and 4000 μm. The composition causes the mineralisation of carbon dioxide (CO2) and of the gaseous chemical compounds known as “nitrogen oxides” (NOx) in the atmosphere. This composition can be added or mixed as an additive in paints, dyes, resins and elastic polymers (gum and natural rubber) in parts with wear, and for any type of covering.
