CATALYST PRECURSOR AND PROCESS FOR PREPARING THEREOF |
摘要 |
A catalyst precursor is prepared by intimately mixing a nickel-aluminium Feitknecht compound with a non-calcined alumino-silicate clay mineral and at the same time and/or subsequently with at least one additive comprising an alkaline earth and/or rare earth metal compound. The resulting mixture is then calcined to produce the catalyst precursor which can be reduced to the catalyst form. The catalyst may be used, for example, in the methanation of gases and the presence of the additive reduces silicon species loss from the catalyst during use. |
