All EPOC Ziegler Natta catalysts are Ti-based and silica supported procatalysts. This means they are inactive as long as there is no external co-catalyst added.

The general performance features of the EPOC family of catalysts allow the production of PE-resins from LLDPE to HDPE with one catalyst only.

Hydrogen selectivity and comonomer response are very good.

The catalystâ&#x20AC;&#x2122;s ability to produce high bulk density polymer results in high settling efficiency in loop reactors and improved throughput in gas phase reactors.

The need for co-catalyst is low.

There is almost no catalyst activity decay over time. The long catalyst lifetime results in stable operations, which makes the EPOC catalysts desirable for long residence time processes such as the ones encountered with series reactor processes.

The EPOC Catalyst Family

Carrier Particle Size

Suitable for all types of processes Gas-phase In gas-phase processes (EPOC 310), the larger particle size of the carrier and other special properties provide the following advantages: →→ good fluidization properties, →→ easily measurable and controllable bed height, →→ high bulk densities, →→ good powder morphology for proper handling, and →→ accurate catalyst injection

loop-reactor

multistage

In slurry loop-reactor processes (EPOC 320), the larger particle size of the carrier makes it easy to obtain:

In multi-stage processes (bimodal), dual gasphase processes, and others, the smaller particle size of the carrier in EPOC 330 - 350 makes it easy to run the reactors:

→→ high slurry densities, →→ high settling efficiency, and →→ good particle morphology.

→→ under high-productivity conditions (low ash), →→ with long residence times without the formation of too large polymer particles, and →→ with great continuity and desired morphology
