Hi

I have to design a CSTR in which polymerization of ethylene to HDPE takes place using a Ziegler-Natta catalyst. Where can I find information about the rate constant, k, or the constants for the Arrhenius equation to get the rate constant (i.e. the pre-exponential factor and the activation energy)? Also, I haven't started the design yet (because I can't find any info about the rate constant) but if needed, would it be safe to use the Z-N catalyst as TiCl₄ since it's exact formula and a lot of its properties is proprietary (I think that's the term they use) information?

Thanks

Anyone?

Hi Dizzy,

 

Consider the articles below.

It has a lot of references to other links that might give you an estimate of the rate constants.

If you are designing for some specific purpose/plant then I would suggest you obtain the actual proprietary values from a licensor.

But if it is for your own practice, this should be enough.
