IEA (International Energy Agency) Co-Operative Project D1 Biomass Liquefaction Test Facility Project: Volume 4, Analysis and Upgrading of Biomass Liquefaction Products

摘要

This volume describes the product analysis and upgrading efforts undertaken in this cooperative project and the results of those efforts. The analytical program involved analysis of biomass liquefaction products recovered from the Comparative Test portion of the Cooperative Project as well as a number of other similar products which were analyzed for comparison. A few of these products were further tested for the potential of upgrading the raw products to higher-valued products such as transportation fuels or chemicals. As a result of these efforts, the many differences as well as similarities among the various products have been quantified. The products basically fall into one of the two categories---pyrolysis products having high oxygen and dissolved water contents with low viscosities and heating values or high pressure liquefaction products which have lower oxygen and dissolved water contents, but higher viscosities and heating values. More importantly, the differences appear to result from the difference in severity of biomass processing as a result of time at temperature and pressure. The effects of feedstock are substantial only when considering the difference between wood and peat. The peat products contain less oxygen but more sulfur and nitrogen while having significant amounts of actual hydrocarbon. Differences in products produced from various species of soft and hard wood were nearly insignificant compared to the differences between wood and peat products. 25 refs., 7 figs., 16 tabs.
