Solution Overview
Problem
The high cost and non-renewable nature of natural gas make it an inefficient fuel source for processes like the Kellogg Reforming System, which requires a more cost-effective, renewable, and easily accessible alternative.
Innovation Solution
A chemically-modified mixed fuel is developed by blending methane gas from multiple sources, including fossil and biogenic sources like landfills, to create a fuel that is cost-efficient, renewable, easy to use, transport, and convert into a usable form, specifically for use in Kellogg Primary Reformer processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If natural gas is used as fuel source in Kellogg Reforming System, then process reliability is maintained, but fuel cost increases and environmental sustainability deteriorates
Solution Approach 1:
The patent combines multiple methane sources (natural gas, landfill gas, biogenic gas) into a mixed fuel composition. This merging allows the system to maintain process reliability through consistent methane content while reducing environmental impact by incorporating renewable biogenic components that offset fossil fuel consumption.
Solution Approach 2:
The patent changes the compositional parameters of the fuel by adjusting the ratios of different methane sources. By controlling methane content within specific ranges (e.g., 60-90% from natural gas, 10-40% from biogenic sources), the system maintains combustion characteristics suitable for Kellogg Reforming while improving sustainability metrics.
2Use of energy by moving object
If natural gas is used as fuel source, then consistent energy supply is provided, but acquisition cost increases
Solution Approach 1:
The patent merges conventional natural gas with lower-cost biogenic methane sources such as landfill gas and agricultural waste gas. This combination reduces the proportion of expensive natural gas required while maintaining sufficient energy supply consistency through the complementary characteristics of different methane sources.
Solution Approach 2:
The mixed fuel composition acts as an intermediary between expensive natural gas and cheaper biogenic gases. By carefully controlling the blend ratios, the system mediates between cost reduction goals and energy supply consistency requirements, achieving optimal economic performance without sacrificing process reliability.
3Quantity of substance
If unconventional natural gas sources are used, then fuel cost decreases, but extraction difficulty and reliability increase
Solution Approach 1:
The patent combines conventional natural gas (high reliability) with unconventional biogenic gas sources (lower cost). By merging these sources in controlled proportions, the system captures the cost benefits of unconventional sources while the conventional natural gas component maintains extraction reliability and supply consistency.
Solution Approach 2:
The patent optimizes the compositional parameters of the mixed fuel to balance cost and reliability. By adjusting the ratio of conventional to unconventional methane sources within specific ranges, the system achieves cost reduction from unconventional sources while maintaining overall supply reliability through the stabilizing effect of conventional natural gas.
4Object-generated harmful factors
If renewable biogenic fuels are used, then sustainability improves, but fuel availability and consistency deteriorate
Solution Approach 1:
The patent merges variable-composition biogenic gases with stable natural gas. This combination improves environmental sustainability through biogenic content while the natural gas component stabilizes the overall fuel composition, compensating for the variability inherent in renewable sources.
Solution Approach 2:
The patent controls the compositional parameters of the mixed fuel by limiting biogenic gas content to specific ranges (10-40%). This parameter control ensures that sustainability improvements from biogenic sources are achieved while maintaining fuel composition consistency suitable for Kellogg Reforming process requirements.

AI summary
A chemically-modified mixed fuel includes methane gas from at least two methane-production sources and can be utilized in any process that incorporates a Kellogg Primary Reformer. A method for producing the chemically-modified mixed fuel described herein includes providing a first methane-containing gas from a first methane-production source, providing a second methane-containing gas from a second methane-production source and blending the first methane-containing gas with the second methane-containing gas at a suitable pressure to form a chemically-modified mixed fuel. In some cases, at least one additional methane-containing gas can be provided from at least one additional methane-production source and blended with the chemically-modified fuel.
