Fuel emulsions for shipping and industry
- RAPTECH UADA technology uses targeted hydrodynamic cavitation to produce stable emulsions from components that are difficult to mix, such as heavy fuel oil, biodiesel and optionally water. The result is a finely dispersed fuel mixture that is characterized by high stability and efficiency.
This high-performance homogenization process with adjustable mixing ratio enables the use of alternative fuels - including renewable energy sources - for emission-reduced and consumption-optimized combustion. The fuel emulsions produced in this way are particularly suitable for applications in shipping and in stationary industrial plants for energy generation.
UADA cavitation technology is suitable for:
- Stable emulsions HFO
- Stable emulsions HSFO | VLFO | ULSFO etc.
- Biodiesel
- Bioethanol
- Pyrolysis oil from plastic waste
- Hydrogenated vegetable oil HVO
- Glycerine
- Water-in-fuel emulsions
- Upgrading heavy fuels
- Fuel reforming
- Improving fuel atomization
- additives

Lower emissions with full ISO 8217 compliance
Optimized combustion of alternative fuels through finely dispersed emulsions
RAPTECH's advanced UADA cavitation technology enables highly efficient homogenization of alternative fuels - especially with demanding components such as heavy fuel oil or biogenic fuel components. By creating ultra-fine emulsions, the droplet size of the alternative fuels is significantly reduced, resulting in improved combustion and higher energy yield.
Thanks to the fine microstructure, emissions can be noticeably reduced. The technology is fully compatible with the requirements of ISO 8217:2024 and is ideal for the use of modern, sustainably formulated fuels. In this way, RAPTECH creates the basis for a future-proof and low-emission energy supply - both in the maritime and stationary industrial sectors.

Production of modern alternative fuels with UADA cavitation technology
The production of high-performance alternative fuels at RAPTECH is based on a multi-stage process using the specially developed UADA cavitation technology. This technology enables precise emulsification of a wide range of components - precisely tailored to customer-specific requirements and areas of application. The result is highly stable alternative fuels that can be used efficiently, sustainably and with low emissions.
RAPTECH completely dispenses with chemical additives such as surfactants, emulsifiers or polymers during production. The emulsions are based on purely physical processes - for a clean, efficient and environmentally friendly solution in the field of alternative fuels.
- Component mixing:
In the first step, the alternative fuels are composed of different base materials in a precisely defined ratio. The formulation is flexible and is individually adapted to the respective area of application.
- Emulsification:
The prepared mixture passes through the emulsification process using UADA cavitation technology. The different phases of the alternative fuels are intensively and stably combined with each other.
- Homogenization:
In the RAPTECH ultrasonic acoustic flow reactor (UADA), the fuel emulsion is finely homogenized. This results in an even distribution of the components, which ensures particularly clean and efficient combustion behavior.
- Quality assurance:
Finally, every alternative fuel is tested for its physical and chemical stability. All emulsions meet the applicable requirements of ISO 8217:2024 and are approved for permanent use in maritime or industrial environments.
