IMPLANTATION OF NI NANO DOMAINS IN REFRACTORY METAL OXIDE SUPPORT BY MEANS OF SOL-GEL ENCAPSULATION - AN EFFECTIVE SOLUTION TO COKE FORMATION IN THE PARTIAL OXIDATION OF NATURAL GAS

摘要

A metal oxide-supported nickel catalyst includes a matrix containing a metal oxide and catalytic sites distributed throughout the matrix and having an intricate interface with the matrix, in which the catalytic sites are selected from the group consisting of nano-nickel(0) domains and nano-nickel(0)-A(0) alloy domains. Also disclosed are a method for preparing this catalyst and a method for using it to produce carbon monoxide and hydrogen by partial oxidation of a C1-C5 hydrocarbon.
