The issue of propylene purification in polypropylene production
Thread Content
During the refining process, why is it necessary to dry first and then deoxidize? Can’t we deoxidize first and then dry? ?
Magazines containing water are toxic to deoxidation catalysts
Agree with the person above. It depends on the properties of the absorbent and desiccant
This issue can be addressed by referring to technical materials on polymer synthesis
What method is used for deoxygenation? Does this indicate that water has an effect on deoxygenation?
Currently, deoxidation in polypropylene and polyethylene plants is generally achieved by using the reaction of copper (Cu) with oxygen to produce copper oxide (CuO).
According to what was said upstairs, copper doesn’t react with water, right? So it should work whether it’s at the front or at the back.
The raw material propylene should first be degassed (of O2, CO, CO2), and then dried to minimize the content of oxides and water
I would like to ask everyone whether there is a sequence for deoxygenation and dearsenification
