Volume 2


The Fast Pyrolysis Handbook Volume 2 is an edited version of the final report of the European Commission and IEA Bioenergy sponsored Pyrolysis Network that officially finished in 2001. It provides a companion volume to the first handbook published in 1999 and it is again intended that this will provide a useful guide both to newcomers to the subject area as well as those already involved in research, development and implementation. A significant feature of this second volume is the greater attention paid to addressing commercial issues such as marketability, transportation and safety.

The benefits from the PyNe Network have been in drawing together the hard core of scientists and engineers involved in developing fast pyrolysis from Europe and North America on a regular basis to share information and help develop the technology. This small group has, however, not been the only beneficiaries as all the meetings have been open to guests and visitors and some meetings have attracted up to 80 participants, all of whom have both contributed to and/or benefited from the activities of the Network.

PyNe is continuing for a third term, again sponsored by the European Commission and IEA Bioenergy and again as a firmly integrated activity between the two organisations. It is now associated with an analogous network on gasification, GasNet, and the two networks will work closely together as ThermoNet to maximise the benefits from integration.

PyNe has been a genuine team effort with contributions by all the members and guests throughout the life of the Network, but the Subject Group leaders in particular have taken the burden of preparing the reports and contributions that make up a significant part of this second volume (Chapters 1 to 8). Other organisations have also contributed to the output of PyNe notably the National Renewable Energy Laboratory in the USA who co-sponsored the report by Jim Diebold (Chapter 11), Natural Resources Canada who funded the report on levoglucosan by Desmond Radlein (Chapter 10), and the Institute for Wood Chemistry in Hamburg who redrew many of the figures in the report by Galina Dobele (Chapter 9). As part of the development of the Subject Groups, which formed the main technical contributions of this Network, most Subject Group Leaders commissioned special reports from experts in different areas as a significant contribution to furthering the science and technology (Chapters 11, 12 and 13), while the Science Subject Group organised a number of very successful workshops resulting in the contributions of Chapters 14 to 18.

Fast pyrolysis is a high temperature process in which biomass is rapidly heated in the absence of oxygen. As a result it decomposes to generate mostly vapours and aerosols and some charcoal. After cooling and condensation, a dark brown mobile liquid is formed which has a heating value about half that of conventional fuel oil. While it is related to the traditional pyrolysis processes for making charcoal, fast pyrolysis is an advanced process that is carefully controlled to give high yields of liquid.

The essential features of a fast pyrolysis process are: very high heating and heat transfer rates, which usually requires a finely ground biomass feed; carefully controlled pyrolysis reaction temperature of around 500C in the vapour phase, with short vapour residence times of typically less than 2 seconds; rapid cooling of the pyrolysis vapours to give the main product - bio-oil.

Author index
Subject index

This handbook is an edited and updated version of the final report of the IEA Bioenergy sponsored Pyrolysis Activity - PYRA - that officially finished in 1998 and accomplished many valuable contributions to the science and technology of fast pyrolysis. It is intended that this handbook will provide a useful guide both to newcomers to the subject area as well as those already involved in research, development and implementation.

The IEA Bioenergy Pyrolysis Task is continuing this work as a collaborative project with the European Commission network on fast pyrolysis of biomass which is now known as PyNe. The European Network was first formed in 1995 as an EC sponsored project in the AIR Programme (AIR3-CT94-1857). At the end of the three-year lives of the Networks in 1997, both sponsoring organisations recognised the benefits from their integration. This led to the present PyNe Network, which is co-sponsored by the European Commission FAIR Programme (FAIR-CT97-3409) and IEA Bioenergy, and which itself is sponsoring the publication of this book as a contribution to the technology.
