Abstract
An improved method for producing calcined coke agglomerates having good stability including adjusting the fluidity of coals or blends of coals to within a range of 1300 DDPM and 3000 DDPM, mixing the coals or blends of coals with char and optionally topped tar in a rotating agglomerating drum and agglomerating the mixture at a temperature between 750.degree. F. and 875.degree. F. (399.degree. C.and 468.degree. C.) for a time to form partially coked green coal agglomerates generally spherical in shape and calcining the partially coked green coal agglomerates at a temperature between 1500.degree. F. and 2000.degree. F. (815.degree. C. and 1093.degree. C). The calcined coke agglomerates are characterized by having a stability of not less than 60%.
