Ramsbottom Carbon Residue

From Wikipedia, the free encyclopedia

Ramsbottom Carbon Residue, which abbreviation is RCR, is well known in the petroleum industry as a method to calculate the carbon residue of a fuel. The carbon residue value is considered by some to give an approximate indication of the combustibility and deposit forming tendencies of the fuel.^[1]

[edit] History

This method originated from Dr J.R. Ramsbottom in England.

[edit] The carbon residue of a fuel

In brief, the carbon residue of a fuel is the tendency to form carbon deposits under high temperature conditions in an inert atmosphere.

[edit] Calculation methods

There are three methods to calculate this carbon residue. It may be expressed as Ramsbottom Carbon Residue (RCR), Conradson Carbon Residue (CCR) or Micro Carbon Residue (MCR). Numerically, the CCR value is the same as that of MCR.
