Abstract
This invention relates to a process for preparing an attrition resistant vanadium-antimony oxide catalyst by adding to a vanadium-antimony oxide catalyst slurry a lithium compound which upon contact with the aqueous catalyst slurry provides hydroxide, such as lithium hydroxide or lithium carbonate. The process comprises the steps of preparing a catalyst slurry comprising vanadium oxide and antimony oxide, adding the lithium compound to the catalyst slurry, concentrating the catalyst slurry to increase the solids content of the slurry, and drying the catalyst slurry to form attrition resistant particles of catalyst.
