Catalysts: Reduced Mo Powder

01

Description

POLEMA produces metal powders and granules for non-coated catalysts used in various chemical processes.

High-purity reduced Mo powder with an average particle size of 2-4.5 micron is effectively used as part of a complex olefin epoxidation catalyst in polypropylene production.

02

specifications

Reduced Mo powder is used as a catalyst for chemical processes, such as a complex, highly effective molybdenum catalyst for the olefin epoxidation in polypropylene production.
