Abstract
Hydrocracking of lignin in the presence of a supported tungsten-nickel catalyst affords phenolic compounds in higher yield and with greater selectivity then previously obtainable. Mildly acidic supports, such as alumina, alumina-silica, aluminum phosphate, and silica-aluminum phosphate, have been found to be particularly effective. When the hydrocracking is done in the presence of water, a lower aliphatic alcohol, or a Lewis acid such as ferrous chloride, increased yields of both cresols and C.sub.6 -C.sub.8 and C.sub.6 -C.sub.9 phenolics are obtained.
