5.7.1 Summary

The aim of this process was the production of bio-oil by the flash pyrolysis of fine wood particles in a 200 kg/h vertical, down flowing entrained flow pilot plant shown in Figure 5.6 (24, 25). The Egemin plant was commissioned in October, 1991, part funded by the EEC from the Joule programme. The research was finished in 1993 and the project was abandoned due to tack of funding and less promising results. A basic problem of this plant was obtaining a sufficiently high rate of heat transfer in the short residence time needed for high liquid yields. This was one of two entrained flow reactors that have been researched (with GTRI), and abandoned.
