GR-342 type ethylene selective hydrogenation deacetylation catalyst

Name: GR-342 type ethylene selective hydrogenation deacetylation catalyst
SKU: 0

The GR-342 acetylene selective hydrogenation and deacetylation catalyst is a highly efficient catalyst specifically developed for polyethylene feedstock purification. Its unique eggshell-shaped structure concentrates the active precious metal components on the particle surface, significantly enhancing catalytic efficiency and reaction selectivity while effectively minimizing ethylene loss during the reaction. The catalyst rapidly hydrogenates trace acetylene in the ethylene feedstock, thereby preventing its toxic effects on the polymerization reaction and ensuring safe and efficient operation of the unit.
