Process for the production of phenolic-rich pyrolysis oils for use in making phenol-formaldehyde resole resins |
摘要 |
A phenolic-rich pyrolysis oil is produced by pyrolysing lignocellulosic material at a temperature of no more than about 550 DEG C under an absolute pressure of no more than about 50 kPa to produce pyrolysis vapors, and condensing the pyrolysis vapors to obtain a condensate consisting of a phenolic-rich pyrolysis oil having a dew point of about 65 to about 75 DEG C. under an absolute pressure of about 15 to about 20 kPa. Such a phenolic-rich pyrolysis can be directly used in making phenol-formaldehyde resol resins.
