Dear Mr. Fantozzi Try the following reference for fast pyrolysis. A.V. Bridgwater and G.V.C. Peacocke, "Advances in Biomass Pyrolysis", Renewable and Sustainable and Energy Reviews, 4, 2000, p 1-73. 26 processes described in detail, all others of interset listed for fast pyrolysis. Right up to date. I suggest searching your library for others. Yours, Cordner Peacocke [Dr.] Director Conversion And Resource Evaluation Ltd. 9 Myrtle House 5 Cassowary Road Birmingham B20 1NE.
