Carbon residue is a byproduct of fuel production, and tests such as Ramsbottom Carbon Residue can determine the amount of residue left after heating or burning. High levels of residue can be harmful to the environment and human health. Additives like ethanol can reduce carbon deposits.
Carbon residue is the amount of carbon produced by a chemical process, such as heating oil. It is primarily considered a byproduct of fuel. When gasoline is burned and used by a motor vehicle engine, it produces exhaust gases that contain carbon monoxide. Carbon residue is what the remaining particles of a fuel product are transformed into. There are tests that can determine the amount of residue that remains after some fuels have been heated or burned.
The test method used to calculate the amount of carbon residue is known as Ramsbottom Carbon Residue (RCR). This test is used to determine how much residue a fuel is likely to leave. It also helps calculate the fuel’s tendency to burn or burn.
The residue can also be calculated as Micro Carbon Residue (MCR) or Conradson Carbon Residue (CCR). Both of these methods are equivalent in that they return the same numeric value. The test is conducted by placing a small amount of fuel oil in a glass container. As the glass is heated within a certain temperature range, the weight is calculated and subtracted from how much the glass weighed before it was heated.
Large quantities of residues can be harmful to the environment. For example, high levels of carbon monoxide can lead to an increase in the concentration of greenhouse gases in the atmosphere. These gases are thought to contribute to global warming, an overall increase in the earth’s average temperature over decades.
Carbon residues can also be life-threatening or poisonous. Exposure to large amounts of carbon monoxide can lead to brain and cell damage, including death from asphyxiation. It is considered a pollutant and some fuels can cause higher amounts of waste than others. Additives, such as ethanol, can be blended into some types of fuel to reduce the amount of carbon deposits.
Residues usually only form when fuel oil reaches high temperatures. Plant machinery, vehicles, and most home heating systems all use a type of fossil fuel that produces a residue when heated. Some engine components can build up carbon deposits over time that may need to be removed periodically to maintain optimum performance. Chemicals such as fuel injection cleaners can help remove some of the deposits that could be the root cause of engine stalling and rough starts.
