Efficient emulsion technology for sustainable fuels in maritime and industrial applications
- RAPTECH UADA technology uses targeted hydrodynamic cavitation to produce stable emulsions based on sustainable fuels. Components that are difficult to mix, such as heavy fuel oil, biodiesel and optionally water, are homogenized to create a finely dispersed fuel mixture. These emulsions are characterized by high stability, efficiency and long shelf life.
Thanks to the flexibly adjustable mixing ratio, sustainable fuels can be optimally adapted to the respective operating conditions. The process enables consumption-reduced, clean combustion and makes sustainable fuels an economically and ecologically convincing alternative for energy supply.
The emulsions based on sustainable fuels produced in this way are particularly suitable for applications in shipping and industrial energy systems.
UADA cavitation technology is suitable for:
- Emulsions with heavy fuel oil (HFO)
- Combinations of HSFO, VLFO and ULSFO
- Biodiesel as a renewable energy source
- Bioethanol for industrial use
- Pyrolysis oil from recycled plastics
- Hydrogenated vegetable oil (HVO)
- Glycerine-based fuel solutions
- Water-in-fuel emulsion systems
- Qualitative upgrading of heavy fuels
- Cavitation-based fuel reforming
- Optimization of atomization properties
- Demand-oriented use of additives

Technological and innovative advantages of sustainable fuels
Lower emissions thanks to sustainable fuels with full ISO 8217 conformity
Optimized combustion of sustainable fuels through finely dispersed emulsions
RAPTECH's innovative UADA cavitation technology enables the efficient homogenization of sustainable fuels, even with challenging components such as heavy fuel oil or biogenic blends. By creating ultra-fine emulsions, the droplet size of sustainable fuels is significantly reduced, resulting in clean, even combustion with increased energy yield.
Thanks to this fine microstructure, emissions such as SOₓ, NOₓ and CO₂ can be significantly reduced. At the same time, the technology meets all the requirements of ISO 8217:2024 and is therefore fully compliant with the current standards for maritime fuels.
RAPTECH thus creates the basis for the industrial use of sustainable fuels - efficient, future-proof and environmentally friendly - both in shipping and in stationary energy systems.

Production of modern sustainable fuels with UADA cavitation technology
The production of high-performance sustainable fuels at RAPTECH takes place in a multi-stage process using the specially developed UADA cavitation technology. This advanced technology enables the precise emulsification of a wide variety of components - individually tailored to customer-specific requirements and specific areas of application. The result is highly stable, sustainable fuels that can be used efficiently and sustainably with low emissions.
RAPTECH consistently avoids chemical additives such as surfactants, emulsifiers or polymers throughout the entire production process. The emulsions are based on purely physical processes - for a clean, resource-saving and environmentally friendly solution in the field of sustainable fuels.
- Component blending:
In the first step, the sustainable fuels are composed of various base materials in precisely defined mixing ratios. The formulas are flexible and are customized according to the application.
- Emulsification:
The prepared fuel mixture then undergoes the emulsification process using UADA cavitation technology. In this process, the phases of the sustainable fuels are intensively and permanently bonded together.
- Homogenization:
In the specially developed RAPTECH ultrasonic acoustic flow reactor (UADA), the emulsion is finely homogenized. This ensures an even distribution of all components and enables clean, efficient and controlled combustion behavior.
- Quality assurance:
Each emulsion based on sustainable fuels is then extensively tested for its physical and chemical stability. All products meet the requirements of ISO 8217:2024 and are certified for long-term use in maritime or industrial applications.
