and more. Concludes with seven chapters on upgrading pyrolysis oils to liquid fuels. Serves as a collaborative effort to combat the long-term rise in CQ, levels resulting from deforestation and the burning of fossil fuels. Specialists from five countries contributed the results of their research. A must for anyone interested in the progress in pyrolysis oil pro duction as a long-term solution to the need for a renewable source of liquid transportation fuels. Ed J.
