1. Specialized Energy & Environment Company Lubricity of Diesel 1. Sulfur contents  Sulfur compounds in fuel generally have good lubricity.  As sulfur content lowered, poor lubricity became a problem. 2.Kerosene blending ratio  As diesel price became higher than Kerosene, blending ratio of Kerosene having bad lubricity, increased. 1. Sulfur contents  Sulfur compounds in fuel generally have good lubricity.  As sulfur content lowered, poor lubricity became a problem. 2.Kerosene blending ratio  As diesel price became higher than Kerosene, blending ratio of Kerosene having bad lubricity, increased. Lubricity Improver is a solution.

2. Specialized Energy & Environment Company Measurement of Lubricity  HFRR (ASTM D6079) In a reservoir filled with diesel, after steel ball reciprocating on a steel plate under certain conditions, measure the amount of wear on the steel plate. Diameter of the patch in micron is HFRR result.  HFRR (ASTM D6079) In a reservoir filled with diesel, after steel ball reciprocating on a steel plate under certain conditions, measure the amount of wear on the steel plate.
