Who are we?
MERGI – A Renergi
Renergi has done research and development within environmental chemistry.
Since the foundation of the company in 1980, extensive research and testing have led to the development of the combustion catalyst MERGI.
Satisfied customers worldwide are using MERGI for fuel-savings, reduced maintanace costs and to reach their ambitious environmental goals.
MERGI distribution centres are stratigic located in Europe, North America, Africa and Asia.
Renergi has been a profitable and growing company since its start and has a “triple A” credit rating.
MERGI offers some distinct advantages.
Improved combustion efficency
Reduces the ignition delay of fuel.
Reduced maintenance costs
improves the combustion efficiency and hence lowers maintenance cost
Lower fuel consumption
Allows the use of lower quality fuels.
Reduces harmful emissions
Reduces the emissions of CO, NOx and HC.
Maritime
This is the largest customer segment within the company. Renergi has provided a fuel optimizing system to the shipping industry for more than 20 years. To get in contact with current users and engineers that have daily experience of the positive effects from using MERGI, please contact us directly.
Cars
A new and fast growing segment of users of MERGI is private owners of cars or smaller car fleets. The reduced fuel consumption let alone finances by far the cost of using MERGI. The improved service level of the engines and reduced pollution is value added additional effects appreciated by many.
Buses and Trucks
Larger landbased transportation companies have a lot to win from using MERGI as a product. Central fueling stations and routines makes it easy to quickly show drastic cost savings from lowered fuel consumption and reduced service costs in the long run. The goal within the industry to improve the environmental effects is also important to consider when evaluating MERGI as a product within this segment.
Close partners to Renergi can also help you to implement specially developed information systems for the industry to be able to track the effects of usage. Please let us know your needs and we will present what Renergi can offer.
Industrial
All industrial applications where combustion engines or processes are used in one way or another are potential beneficiaries from using MERGI. One example from Sweden is a local oil company that delivers oil for the warming of private houses. They add MERGI to their central oil tanks in the right proportions and than let their customers enjoy the benefits .The effects are so apparent, that the addition of MERGI as a concept, is even being used in the Company´s direct marketing material.
MERGI Combustion Catalyst
The leading combustion catalyst in the market
MERGI Combustion Catalyst reduces the ignition delay of fuel, which improves the combustion efficiency. This results in lower maintenance costs (reduced piston ring breakage and seizure, ring and liner wear, fouling of turbo chargers and economizer, etc), and lower fuel consumption. It also allows the use of lower quality fuels and reduces the emissions of CO, NOx and HC. MERGI improves the combustion of fuels, such as heavy fuel, MDO, gas oil, gasoline / petrol, diesel. It can be used in marine and stationary engines (slow, medium and high speed) as well as in boilers.

Purpose
MERGI Combustion Catalyst reduces the ignition delay of fuel, which improves the combustion efficiency. This results in lower maintenance cost as well as lower fuel consumption. It also allows the use of lower quality fuels and reduces the emissions of CO, NOx and H
Application
For the combustion of fuels, such as heavy fuel, MDO, gas oil, gasoline / petrol, diesel estimated dosage ratio is 1:4000
Application system
Marine and stationary engines: slow, medium and high speed, boilers, cars and trucks.
Application method
For civilian use in trucks and cars we supply specialized dosage bottles. MERGI Combustion Catalyst may also be introduced in to the tanks at dedicated filling stations for fleet users. For marine use, a fully automated dosage system will be supplied that is connected to, and activated by the transfer pump.
Handling
MERGI Combustion Catalyst contains petroleum distillate and is harmful if swallowed. Material Safety Data Sheets are available on request.
Quality control
MERGI Combustion Catalyst are continuously checked at The Swedish National Testing and Research Institute.

More information about the combustion process
Innovations in engine design, like turbo charging and direct injection, have been steadily improving engine efficiency. However, today’s fuels have difficulty meeting the requirements of modern engines. This is mainly due to the deterioration in fuel quality.
Deterioration of marine fuel quality
In the 1950’s, refineries processed crude petroleum by atmospheric distillation, producing straight run distillates and residual fuels. Since then, the quality of marine fuels has deteriorated as catalytic cracking has become standard and modern marine fuels, although their caloric value has remained the same, have poor combustion characteristics.
The catalytic prosess
Petroleum based liquid fuels contain many hydrocarbons. To convert these fuels into energy, combustion must take place. The result of a complete combustion is water and carbon dioxide. Incomplete combustion produces carbon monoxide, soot and tar.
Small and light hydrocarbon molecules, like those found in gas and naphtha, burn easily. The large and heavy hydrocarbon molecules in residual fuel oil are not easily ignited, so they need a higher temperature to achieve complete combustion. In the combustion process, creation of free radicals affects the speed of combustion. Thermal cracking occurs in molecules when a sufficient temperature is reached. The components that are created during thermal cracking are extremely reactive and immediately seek to combine with oxygen atoms. This oxidation releases heat, which leads to further thermal cracking.
A chain reaction is thereby created.
The MERGI Combustion Catalyst improves the ignition quality of fuels, so releasing more energy, reducing hydrocarbon residues and producing cleaner emissions. For instance, the catalyst is designed to reduce ignition delay and improve combustion efficiency. Better combustion leads to cleaner piston rings allowing a tighter fit between rings and liner. MERGI includes components that undergo thermal cracking at a considerably lower temperature (approximately 200oC) than hydrocarbon molecules. The concentration of free radicals is increased in an early stage of the ignition process. This in turn improves the combustion process, causing a far more intense combustion once the oxidation begins. The result is a more complete combustion of the fuel.
This increase in temperature allows the oxidation of soot and tar (hydrocarbons with a low content of hydrogen) which otherwise would remain to form deposits in the engine , or to be expelled with the exhaust gasses as pollution. Complete combustion reduces the carbon monoxide and increases the heat/energy released from the fuel.
The increased temperature also improves the condition of the valves and the piston rings by burning off soot and carbon deposits and so improving compression. The reduced cylinder leakage improves the effectiveness of the engine and reduces the amount of fuel consumed.Innovations in engine design, like turbo charging and direct injection, have been steadily improving engine efficiency.
