Liquid Carbonaceous Fuels TRIZ Cases

A single-stage sweet hydrocracking and separation route preserves jet-range yield while maintaining low freeze points in renewable jet fuel.

Partial hydrodeoxygenation keeps oxygen low enough for marine fuel stability and corrosion control without the cost of full upgrading.

Compressed gas keeps the polar solvent liquid at high temperature, enabling acid-assisted delignification with lower solvent use and less fouling.

Blending two different monoalkyl alkenyl succinates in fuel creates a synergistic protective film that cuts engine wear and friction.

Azeotrope-forming solvents remove water from pyrolysis oil under mild heating, limiting oligomers, coking, and corrosion in downstream upgrading.

An integrated CO2-to-methanol, aromatics, and Fischer-Tropsch route raises aviation fuel aromatics while preserving cold flow properties.

Pour point depressants keep plastic-derived synthetic feedstock fluid at low temperatures by preventing wax gelation that blocks filters and pipelines.

Reactive polybutene added to gasoline at controlled levels cuts burn duration while raising engine power and acceleration in spark ignition engines.

A two-stage paraffin upgrading route raises aviation fuel yield and cold properties while reducing C1-C4 gas formation and catalyst stress.

A hydroisomerization and hydrocracking route raises renewable aviation fuel yield while improving cold properties and high-ratio blendability.

Specific Mannich detergent fuel additives cut particulate emissions in GDI engines while preserving the power and efficiency benefits of direct injection.

Balancing cold flow and viscosity, this hydrocarbon blend uses controlled C15-C22 paraffin ratios for arctic diesel without additives.

Precise Mannich detergent ratios and PIB-substituent structures reduce GDI particle emissions while retaining direct-injection power benefits.

Controlling C4-C9 paraffin branching raises octane and blendability, allowing more renewable gasoline component in fuel blends.

A quaternary ammonium internal salt and Mannich base blend controls injector deposits at lower treat rates while improving fuel flow and engine efficiency.

A recycle hydrocracking route lifts aviation fuel yield and cold properties while limiting C1-C4 gas formation and catalyst stress.

Terminal unsaturated polyisobutene sulfonates improve lubricant and fuel solubility, shear stability, viscosity behavior, and corrosion resistance.

An upstream bicomponent-glass layer sequesters fuel degradation products before they plug the downstream cellulose layer, extending diesel filter life.
