摘要：

Synthetic TO (1 tetrahedral layer/1 octahedral layer) phylloaluminosilicates of Ni-Mg-Al with amesite (septechlorite) structure were synthesized and their evolution during calcination in inert and reducing media was studied. After treatment at 700-800degreesC in hydrogen, the samples consisted of dispersed metallic nickel particles supported on TOT Mg-chlorite-vermiculite; none of the catalysts studied contained SiO2. The samples were stable in inert gas and hydrogen atmospheres at 850degreesC, as well as in hydrogen plus steam at 20 bar and 650degreesC. Thus, we consider Ni-containing amesite-like compounds to be suitable catalysts for the methane steam reforming process.
