Recycling Actification of the Obsolete Petroleum Products;

Progress in solvent denitrogeneration of petroleum products;

The bromine value of petroleum products was determined by potential titration in mixed solvents of glacial acetic acid,trichloromethane,methanoland sulfuric acid,this method was compared with indicator titration,the experimental results show the method relative standard deviation is smaller.

Determinatiom of suspend mechanical impurity in petroleum product by microwave drying;

In this paper,the carbon redidue of petroleum products determinated by Conradson method and Micro method were discussed.

Most of the standard test methods for determining petroleum products flashing point in the world are discussed, also mentioning the origin and development of flashing point.
