Abstract
Processes of producing cresols from a phenols containing feed are described. The processes involve a combination of dealkylation and transalkylation processes. The dealkylation process converts the heavy alkylphenols in an alkylphenols stream to phenol and olefins. The olefins produced in the dealkylation process are separated out. The methylphenols, which are not converted in the dealkylation process, and phenol react in the transalkylation process to generate cresols.
