The Synthetic study of Carboxymethyl Starch with a high degree of Substitution and high viscosity;

Development on naval vessel high viscosity air-compressor oil;

Preparation method, characterization and application research of sodium carboxymethyl starch(CMS)with high viscosity are briefly introduced.

Using stainless steel tubes(wall thick 1 mm) heated by the direct passage of a current which has a maximum about 500 A, and a aqua CMC (sodium carboxy methyl cellulose),an experimental study of flow boiling heat transfer to a highly viscous fluid in vertical downward flow is presented for a consistency index η= 0.

n experimental investigation of flow boiling heat transfer to a highly viscous fluid in verticaldownward flow was carried out.

Heat transfer enhancement for highly viscous fluids in solution polymerization for synthetic rubber is an important engineering problem which can be solved effectively by using scraped-surface apparatus .

This paper describes a viscosity reducing method for Orinoco Heavy Crude (Venezuela) with associating, dissolving and diluting techniques,applying the method,the viscosity of the heavy crude is descended below 500 mPa · s at 30℃ from 20000 mPa · s at 50℃ ,and the volume of diluents (naphtha,gasoline etc.

The new research advances in the technologies of melt phase polycondensation and swollen solid phase polycondensation due to the presence of supercritical CO2 were reviewed.

To solve the problem of regenerating Baosteel's mixed waste oil with medium-high viscosity , Baosteel Used-oil Treating Station did a lot of research and experiments, and finally successfully developed the waste oil recycling process,which involves flocculation-sedimentation and three-stage filtration, and a vacuum water-separator.
