Several catalytic reforming processes are used for converting hydrocarbons into syngas. The use of a catalyst is during such reaction, is to allow the reactions to be carried out at reasonable temperatures. However catalyst usually deactivates due to poisoning that is mainly caused by secondary reactions, which could be avoided if the heating is local. In order to determine the efficiency of local heating during reforming test a catalyst should be deposited on the surface of a carbon coated receptor. Several synthesis methods have been tested in order to deposit nickel or spinel NiAl2O4 on the surface of the C-SiO2. The three most efficient methods that provided the best deposition results are: polyol-sonication process, hydrothermal synthesis, and plasma technique.
