CATALYSTS [CHEMFRAME]

PRODUCTS/

Catalysts

We not only develop technologies but also manufacture catalysts for the processes we license.

We also supply imported catalysts. Since their stated specifications often do not guarantee the required selectivity or service life, we carefully select imported catalysts at the start of each project. Every supplied batch undergoes long-duration testing with real reaction mixtures in continuous-flow laboratory units.

All catalyst batches we ship are tested in continuous-flow laboratory units.

K-18

K-18 catalyst is used to decompose high-boiling by-products (HBBPs) of isoprene synthesis and the pyran fraction containing 4-methyl-5,6-dihydro-α-pyran (MDHP) and 4-methylenetetrahydro-α-pyran (MTHP), or to decompose HBBPs together with the pyran fraction to obtain isoprene, isobutylene and formaldehyde.

Activated alumina
Used for vapour-phase dehydration of methylphenylcarbinol to produce styrene.
