Determination of Hydrogen and Carbon Contents in Heavy Oils by NMR Spectroscopy;

The importance of heavy oils in petroleum processing is increasing.

Some application illustrations of combustion_supporting additive which has been made by us for burning process of heavy oils are given in this paper.

It has been generally accepted that internal diffusion in catalyst has become increasingly important for Residue Fluid Catalytic Cracking(RFCC) because of the large molecules of residue,high reaction temperature and the short contact time between the catalyst and residue during the catalytic process.

The filtration system for slurry purification was successfully used in a commercial residue fluid catalytic cracking( RFCC ) unit.

It is characterized by good selectivity to gas olefins,strong ability for residue conversion,low coking yield and strong resistance to heavy metal pollution.

Synthesis of environmental protection type emulsifier for heavy oil;

Practice on replacement of heavy oil by coal gas for agglomerated ore drying operation;

Study on catalyst RCH for catalytic cracking of heavy oil;

A-heavy oil and wood powder are cofired to reduce the oil consumption and cut down the harmful exhaust emission.

The conclusion is that both dead oil and colophony can improve efficiently the dry strength,resistant moisture ability of the starch core sand;the comprehensive.

This paper discusses the mechanism of dead oil emusification,gives an example of its application in industrial boilers in Daqing Petrochemical General Factory.
