The latest progress of residuum catalytic cracking reaction technology,such as pre-lifting with light hydrocarbon,feed atomized spray nozzle,stopping reaction medium,rapid separation of gas and catalyst and queching of oil gas at exit of commercial riser,were introduced.

Fuzzy-PID hybrid control of the work parameters of atomizing nozzle;

This paper explores atomizing nozzle structure, feed, oxide content and impurities as well as bulk density and size distribution that affect gas volume liberated from the zinc powder, and presents the research results that the atomizing nozzle structure and assembled accuracy are closely related to the gas volume librated from zinc powder.

On the foundation of gas atomization , supersonic atomization and domino effect of electric charge ,the article combined solid atomization and effect of electric charge ,the author successfully designed a novel double liquid atomization nozzle which combined the solid and electric field ,and offered powerful technical auspices for increasing atomization effect and preparing remoter metal powder .

Based on the study of the atomization(nozzles) for fuels like petroleum and for water,the atomization nozzles for superfine metal powders are described in detail.

The structure design of the atomization nozzle applied to the metal powder production is analyzed.

The experimental study of critical airblast atomizer;

In this paper, the spray characterisitics of an internal blend airblast atomizer were studied.

Commercial application of CS-Ⅱ type heavy oil FCC feed atomizing nozzle
