Fluidizable particulate solid catalyst composition

摘要

A composition comprises (a) particulate, precalcined low silica content zirconia, especially one stabilized with yttria, in concentration ranging from about 10 wt% to about 99.9 wt%, with (b) a particulate catalyst, suitably a nickel-on-alumina catalyst, in concentration ranging from about 90 wt% to about 0.1 wt%. The composition provides a catalytic contact mass suitable for use in fluidized bed high temperature oxidizing, reducing and hydrothermal environments, including synthesis gas generation.
