The residual carbon value of an oil product refers to the mass percentage of the oil product's carbon residue formed after the evaporation and thermal cracking process under a specific high temperature condition. The value of residual carbon is related to the chemical composition and ash content of

In order to judge and compare the quality of the fuel and make a reasonable selection, some performance indicators are specified for the fuel.1. Indexes that affect fuel combustion performance: cetane number (cetane number); diesel index (Diesel index); distillation range (distillation range); calor

What are the products of petroleum atmospheric distillation and vacuum distillation？ Distillation is a method of separating each substance in a crude oil mixture by using the difference in boiling point.

What should be paid attention to when doing viscosity test1. When the viscosity is measured, the test temperature is different, and the constant temperature time is also different; The sample for measuring the viscosity must first be dehydrated and filtered of mechanical impurities
