PRC type ethylene CO removal catalyst

The PRc-type ethylene carbon monoxide removal catalyst is a highly efficient purification material designed specifically for the polyolefin industry. With copper oxide as its core active component, this catalyst efficiently removes trace carbon monoxide (CO) from ethylene feedstock under mild conditions. It also removes trace amounts of oxygen and sulfur, making it a critical defense against expensive downstream polymerization catalysts (such as Ziegler-Natta catalysts).
Its key feature is its recyclability. Through a "removal-regeneration" cycle (CO reduces CuO to Cu during removal, and air is introduced to reoxidize Cu to CuO during regeneration), catalyst performance can be restored multiple times, significantly extending its service life and reducing overall costs for customers. The product features high removal accuracy, excellent mechanical strength, superior selectivity, and a wide reaction temperature range, ensuring ethylene feedstock purity and ensuring long-term, stable ope

◼What is the main function of GR-342 deacetylene catalyst?

Its main function is to selectively hydrogenate and convert the trace acetylene in the ethylene raw gas, remove harmful impurities, and ensure the smooth progress of the polyethylene polymerization reaction.

◼Why does this catalyst adopt an eggshell structure design?

The eggshell-shaped structure can concentrate precious metals on the surface of the particles, thereby increasing the reaction rate and selectivity while reducing the loss of ethylene due to over-hydrogenation.

◼What are the advantages of using GR-342?

The main advantages include: high selectivity (reduced ethylene loss), high stability (extended service life), and high efficiency (rapid removal of acetylene), thereby ensuring long-term stable operation of the production unit.

◼In which industries is this catalyst mainly used?

It is mainly used in the petrochemical industry, especially in the polyethylene production process, for the refining and purification of ethylene raw gas.
