ABSTRACT:
A direct, simplified and relatively salt-free process is described for making anionic, hydrotalcite-type pillared clay compositions which contain nickel, and their heat-treated derivatives. Compositions of the invention are manufactured from ractants which contain a relatively minor amount of metal salts or, preferably, contain essentially no metal salts. Preferred compositions made by the process form a number of new nickel-containing catalytic materials which are unusually resistant to deactivation, for example resistant to coke formation when used to catalyze chemical conversions of a hydrocarbyl compound with an oxygen-containing gas at elevated temperatures to form synthesis gas.
