Solution Overview
Problem
Existing fuels derived from petroleum produce high greenhouse gas emissions and often compromise engine performance characteristics when blended with low carbon fuels from renewable biomass.
Innovation Solution
A blended fuel comprising a petroleum fuel and a low carbon fuel produced from renewable biomass, where the biomass is converted into syngas and then reacted with a catalyst to produce a low carbon fuel, which is blended in varying proportions to improve both greenhouse gas content and engine performance characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If low carbon fuel from renewable biomass is blended with petroleum fuel, then well-to-wheels greenhouse gas content is reduced, but engine performance characteristics are reduced
Solution Approach 1:
The patent applies parameter changes by modifying the chemical composition and physical properties of the low carbon fuel through controlled conversion processes. By adjusting reaction conditions, catalysts, and processing parameters, the fuel's cetane number, lubricity, and stability are optimized to meet or exceed petroleum fuel specifications while maintaining low greenhouse gas emissions.
Solution Approach 2:
The patent creates a composite fuel system by blending low carbon fuel derived from renewable biomass with petroleum-based fuel. This composite approach allows the mixture to achieve both environmental benefits (reduced WWGGC) and performance requirements (cetane number, lubricity) that neither component could achieve alone, resolving the contradiction between sustainability and engine performance.
2Reliability
If conventional petroleum fuel is used, then engine performance characteristics are maintained, but well-to-wheels greenhouse gas content is high
Solution Approach 1:
The patent introduces low carbon fuel derived from renewable biomass as an intermediary substance that mediates between the need for high engine performance and low greenhouse gas emissions. This intermediary fuel component provides the necessary chemical properties for engine performance while simultaneously reducing the overall carbon footprint of the fuel system.
Solution Approach 2:
The patent changes the parameters of the fuel system by incorporating renewable biomass-derived components with different chemical compositions and combustion characteristics. These parameter changes result in reduced well-to-wheels greenhouse gas emissions while maintaining acceptable engine performance through careful formulation and blending strategies.
3Use of energy by moving object
If first generation biofuels are used, then renewable energy source is utilized, but well-to-wheels greenhouse gas content is close to or greater than petroleum fuels
Solution Approach 1:
The patent replaces the conventional mechanical/chemical processing methods of first generation biofuels (such as simple fermentation and distillation) with advanced conversion technologies. This substitution enables more efficient utilization of renewable biomass feedstocks, producing fuels with significantly lower well-to-wheels greenhouse gas emissions while maintaining renewable energy credentials.
Solution Approach 2:
The patent fundamentally changes the production parameters and conversion processes of biofuels by moving from first generation methods to advanced second generation technologies. These parameter changes include using different feedstocks (lignocellulosic biomass), different conversion pathways (gasification, pyrolysis, biochemical conversion), and different purification methods, resulting in fuels with superior greenhouse gas reduction performance.

AI summary
The present invention provides a blended fuel and methods for producing the blended fuel, wherein a low carbon fuel derived from a renewable resource such as biomass, is blended with a traditional, petroleum derived fuel. A blended fuel which includes greater than 10% by volume of low carbon fuel has an overall improved lifecycle greenhouse gas content of about 5% or more compared to the petroleum derived fuel. Also, blending of the low carbon fuel to the traditional, petroleum fuel improves various engine. performance characteristics of the traditional fuel.
