The key product of co-coking is a blast-furnace coke. In the cokes obtained, the decisive parameters were therefore observed using the standard method of Nippon Steel Comp., reactivity to C[O.sub.2] (CRI) and coke strength after the reaction with C[O.sub.2] (CSR).

For if we--based on experience--consider the blast-furnace coke with the CRI value below 36% to be of good quality and those with the values 36-40% to be acceptable, then it would probably be only the coke with a mixture of 3% rubber that would not be possible to use in a blast furnace on its own.
