Solution Overview

Problem

Current methods for removing carbon dioxide and other carbonaceous materials from compositions are inefficient, as they do not effectively address the need for substantial removal and often require stringent operating conditions, leading to incomplete carbon sequestration and additional pollutant production.

Innovation Solution

A process involving the reaction of carbonaceous materials with sulfur compounds, such as hydrogen sulfide or carbon disulfide, to form products that include elemental carbon and sulfur, allowing for at least 50% removal of carbonaceous materials, with the ability to produce usable carbon and sulfur products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional methods are used to remove carbon dioxide and carbonaceous materials, then the process can be simplified, but the removal efficiency is insufficient and additional pollutants are produced

Engineering Contradiction:

Improvecarbonaceous material removal efficiencyVSAvoidpollutant production

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful carbon dioxide and carbonaceous materials into useful products (elemental carbon and hydrogen sulfide) through a chemical reaction with hydrogen sulfide. This transforms the harmful carbon sequestration problem into a beneficial production process, eliminating pollutants while creating valuable carbon and sulfur compounds.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent changes the chemical parameters of the system by introducing hydrogen sulfide as a reactant, transforming the reaction pathway from conventional combustion or oxidation methods. This parameter change enables complete conversion of carbonaceous materials into elemental carbon and hydrogen sulfide, improving removal efficiency while avoiding harmful pollutant formation.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If conventional carbon removal methods are used, then the operating conditions can be maintained as-is, but substantial removal of carbonaceous materials is not achieved

Engineering Contradiction:

Improvecarbonaceous material removal rateVSAvoidcarbon sequestration completeness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent uses hydrogen sulfide to convert carbonaceous materials into elemental carbon and hydrogen sulfide, creating a reliable and complete removal process. This chemical transformation achieves substantial removal rates while maintaining high reliability in carbon sequestration, as the reaction completely converts carbon compounds rather than leaving partial products.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent replaces conventional mechanical or physical removal methods with a chemical reaction system. By using hydrogen sulfide to chemically transform carbonaceous materials, the process achieves both high removal rates and complete sequestration, overcoming the limitations of conventional methods that cannot simultaneously achieve both productivity and reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If existing carbon removal processes are used, then the process complexity can be maintained low, but stringent operating conditions are required leading to incomplete removal

Engineering Contradiction:

Improvecarbonaceous material removal efficiencyVSAvoidoperating condition stringency

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent changes the chemical parameters by introducing hydrogen sulfide as a reactant, which enables the reaction to proceed under less stringent operating conditions. This parameter change allows for complete carbonaceous material removal without requiring extreme temperatures, pressures, or other harsh conditions, thereby reducing operational complexity while maintaining high productivity.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent converts the need for stringent operating conditions into a benefit by using hydrogen sulfide to drive the reaction. This approach achieves complete removal efficiency without requiring complex operating conditions, as the hydrogen sulfide reactant facilitates the transformation under milder conditions, thereby reducing device complexity while maintaining high productivity.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
