Research
& Development

The
Worms Research and Development Centre is equipped with
facilities for the preparation, characterisation and evaluation
of FCC catalysts and additives. Experimental
catalysts are prepared in the pilot plant before going to full
scale manufacture. The pilot plant is capable of simulating the
Worms manufacturing plants on a small scale and is used not only
to prepare catalysts but also to indentify optimum processes
prior to further development.
Prior to catalytic testing,
catalysts are deactivated under carefully controlled conditions.
Catalytic performance is then quantified using either large
scale or small scale reactors. Davison uses fixed bed MAT
reactors for measuring catalyst selectivities and feed
crackability. This test was adopted as a standard for fluid
cracking catalysts by the American Society of Testing Materials
(ASTM). State-of-the-art gas chromatographs (GC) are used with
the MAT reactors for precise measurement of product yields.
Grace Davison
has made a number of improvements on the original MAT test
including the introduction of a short contact time (SCT) MAT
technique.
Catalysts can also be
evaluated in the larger scale Davison circulating riser pilot
plant (DCR). The DCR was developed in 1986, and is now
considered the industry standard for FCC pilot plants.
