Catalytic dehydroxylation of phenols. [Metal sulfides]

Patent ·
OSTI ID:6530205
Phenolic compounds are dehydroxylated in the vapor phase by contacting with a reducing atmosphere substantially comprising hydrogen sulfide as the reducing agent in the presence of a sulfur-tolerant metal sulfide catalyst. The additional presence of hydrogen gas helps to desulfurize the catalyst and maintain catalytic activity. The process is useful in the treatment of phenolic naphtha fractions present in coal liquids, produced by pyrolysis or direct coal liquefaction.
