Fluidizable zinc titanate materials with high chemical reactivity and attrition resistance

摘要

Highly durable and chemically reactive zinc titanate materials are prepared in a particle size range of 50 to 400 mu m suitable for a fluidized-bed reactor for removing reduced sulfur species in a gaseous form by granulating a mixture of fine zinc oxide and titanium oxide with inorganic and organic binders and by optional additions of small amounts of activators such as CoO and MoO3; and then indurating it at 800 DEG to 900 DEG C. for a time sufficient to produce attrition-resistant granules.
