Abstract
Catalyst precursor pellets, suitable for use, after reduction, as high temperature shift catalysts, comprising oxides of iron and chromium and including particles having an aspect ratio of at least 2 and an average (by weight) maximum dimension of at least 500 nm. The particles are preferably acicular and particularly are acicular iron oxide, alumina, or zinc oxide particles.
