The properties of spent cracking catalyst samples from various refineries are studied. The recycling of spent cracking catalysts to produce ceramic products, namely to manufacture electrical porcelain and fireclay refractories, is justified. The technology for products of subgroup 110 is developed and can be based on the existing technological scheme and equipment. Cracking catalyst wastes (10 – 15 wt.%) can be introduced into the initial charge composition without deterioration of the properties.
