Abstract
Official abstract text for this publication.
A metal loaded catalyst comprises a support and main active metal components and optional auxiliary active metal components, wherein the main active metal components are elementary substances and obtained by ionizing radiation reducing precursors of main active metal components. The catalyst can be widely used in the catalytic reactions of petrochemistry industry with high activity and selectivity. The catalyst can be used directly without being reduced preliminarily by hydrogen.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparation of a supported metal catalyst, comprising applying ionizing radiation on a system comprising a precursor of a primary metal active component, a carrier, a free radical scavenger and water, to reduce at least the primary metal active component precursor into the primary metal active component in elementary state, wherein the step of applying the ionizing radiation to carry out the reduction is conducted in either of the following manne…
