Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diesel/heavy oil fuels face challenges in meeting market access standards due to low flash point temperatures and poor combustion performance, particularly with the use of heavy alkanes and high synthesis costs in existing alternative fuel formulations.
Innovation Solution
A liquid fuel is formulated by blending a light oil component of C6-C12 alkanes with a catalytic component of C13-C16 alkanes and a heavy oil component, adjusting the proportions to enhance the flash point and combustion performance, ensuring compatibility and safety, and allowing for a wider range of market applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heavy oil is used as the main fuel component, then cost and safety are improved, but combustion performance deteriorates
Solution Approach 1:
The patent combines heavy oil with light oil components (C6-C12 alkanes) and catalytic components (C13-C16 alkanes) to create a blended fuel. This merging allows the fuel to maintain the cost and safety advantages of heavy oil while incorporating the combustion benefits of lighter hydrocarbons, resolving the contradiction between cost-effectiveness and combustion performance.
Solution Approach 2:
The invention creates a composite fuel formulation consisting of multiple hydrocarbon components with different properties. By composing the fuel from heavy oil, light oil, and catalytic components in specific proportions, it achieves a balance between economic viability and combustion efficiency, transforming a single-component limitation into a multi-component solution.
2Adaptability or versatility
If conventional diesel/heavy oil fuel is used, then availability is maintained, but flash point temperature and combustion performance fail to meet market standards
Solution Approach 1:
The patent systematically adjusts the parameters of the fuel formulation by varying the proportions of heavy oil, light oil, and catalytic components. By changing these compositional parameters, the flash point temperature and combustion characteristics are optimized to meet market standards while maintaining fuel availability and usability.
3Reliability
If alternative fuels are synthesized by Fischer-Tropsch process, then combustion performance is improved, but raw material source and cost are limited
Solution Approach 1:
Instead of using expensive synthesized alternatives, the patent employs readily available and inexpensive hydrocarbon components from conventional oil refining. The formulation uses common light oil and catalytic components that are easily obtainable, avoiding the need for costly Fischer-Tropsch synthesis while achieving acceptable combustion performance.

AI summary
A liquid fuel obtained by blending heavy oil by selectively introducing hydrocarbon substances. The liquid fuel consists of a light oil component consisting of C6-C12 alkane, a catalytic component consisting of C13-C16 alkane, and a heavy oil component. On the basis of the liquid fuel, the mass fraction of the heavy oil component is 10%-90%, the mass fraction of the light oil component is 0-49%, and the mass of the catalytic component accounts for 86% or more of the mass of the light oil component; and the liquid fuel may also contain an aromatic hydrocarbon having a mass fraction of 0-15%. The obtained liquid fuel has good driving performance, combustion performance and safety, and can be applied to a diesel engine system, a diesel/heavy oil combustion system, etc., as a mixed fuel oil.
